+This document is a brief description of the main
+coding style conventions in dwarfdump.   Many of them
+will be obvious from the code, but over time some
+accidental diffences crept in.
+
+
+Code should be indented in multiples of 4 spaces, and
+tabs should not be used to indent the source code.
+Use the dicheck program to check indenting.
+
+The struct naming convention is 'struct  my_struct_s' for the
+struct defined here  (meaning the name should end with _s).
+It is better to not do struct typedefs of local structs.
+Coders should type  'struct mystruct_s'.  Readability
+is much more important than brevity.
+
+Any data or function not referenced outside the
+defining source file should be declared 'static'.
+
+Any duplicated code is a candidate for refactoring
+into a subprogram.
+
+Function names should be all lower case with underbars
+with the goal that statements and comments 'read well'.
+
+Variables should be lower-case with
+underbars for readability.   It's ok for a small loop
+with counters to use single letter names like i or k or m.
+
+Structure members should have a struct-specific
+2-character prefix to the name (followed by
+an underbar). That makes it much
+easier to grep for uses of members.
+
+Try to keep lines under 80 characters in length.
+
+Ensure every if() has {} to enclose the actions.
+
+Use libdwarf.h types for all the data objects you define,
+though sometimes an 'unsigned' or 'int' or 'size_t' is
+ok in restricted circumstances.  Dwarf_Unsigned and 
+Dwarf_Signed are the preferred integer types for general use.

+David Anderson: December 2006
+The code in the dwarfdump directory is (if you look
+in each file) covered by the GPL (not the LGPL).  The
+DWARFDUMPCOPYRIGHT file, though, said (before December 24,
+2006) the copyright is LGPL.  There is no doubt in my (David
+Anderson) mind that the intent was always that dwarfdump be
+GPL and the copyright markings in each file are correct.
+
+There are three files marked with the LGPL: tag_tree.list
+tag_attr.list acconfig.h.  These markings are left as is and
+these are are therefore LGPL files.
+
+The DWARFDUMPCOPYRIGHT file now (Dec 24 2006) has both
+copyrights and an explanation of where each applies.
+
+
+
+-------------------------------------------
+The text present for years, thru Dec 23, 2006:
+The files:
+	dwarfdump.c
+	and all the .h and .c files in this implementation of
+	dwarfdump are copyrighted according to the file
+	DWARFDUMPCOPYRIGHT.

+
+2005-04-13 David Anderson <davea@sgi.com>
+      * print_sections.c: Factors out common print code into
+        a new routine. Avoid indexing past end of register names
+        array.  Adds checks and prints so that certain errors
+        in pubnames-like sections are printed usefully (and dwarfdump
+        then stops if libdwarf gave an error).
+        
+2005-03-21 David Anderson <davea@sgi.com>
+      * dwarfdump.c: Add -F flag to
+        request .eh_frame section print. Changed -f flag meaning
+        to print .debug_frame only. -a flag no longer
+	prints .debug_frame by default.
+      * print_sections.c: avoid printing an eh_frame we don't understand.
+	Add new information per CU when printing line info: specifically
+        the line section offset.  
+      * globals.h: Added arguments to print_frames() for -F flag.
+
+2005-03-18 David Anderson <davea@sgi.com>
+      * print_sections.c: Correct macro section printing.
+
+2004-10-28 David Anderson <davea@sgi.com>
+      * DWARFDUMPCOPYRIGHT config.h defs.h dwarfdump.c globals.h
+	makename.c makename.h print_die.c print_exception_tables.c 
+	print_reloc.c print_sections.c tag_attr.c tag_attr.list

+        corporate address change.
+
+2004-10-26 David Anderson <davea@sgi.com>
+      * acconfig.h: removed. Was old style autoconf usage.
+      * configure.in: Updated AC_DEFINE usage, adding args 2 & 3.
+      * config.guess: Updated. timestamp='2004-06-11'.
+      * config.sub: Updated.  timestamp='2004-03-12'.
+      * configure config.h.in: regenerated with autoconf 2.58.
+
+2004-05-14 David Anderson <davea@sgi.com>
+
+      * print_die.c (print_die_and_children): Change to iteration
+        on siblings (still recursing on children).
+
+	
+2004-03-30 David Anderson <davea@sgi.com>
+      * dwarfdump.c (main): getopt() string should contain k:g
+        not kg:    Thanks to Peter Seiderer for pointing this out.
+
+2003-12-31 David Anderson <davea@sgi.com>
+      * README: Added configure example.
+      * Makefile.in: Removed bogus LIBS line, updated copyright date.
+      * acconfig.h: Added LGPL copyright to match libdwarf
+	Silly, but it matches libdwarf version boilerplate.
+      * config.guess config.sub: new versions from automake-1.6.
+      * config.h.in configure: Regenerated.
+
+
+2003-10-06   David Anderson <davea@sgi.com>
+     * dwarfdump.c print_sections.c: applied indent(1).
+     * print_die.c: applied indent and added ; after
+       invocations of macros PUSH_DIE_STACK POP_DIE_STACK SPACE
+       as these were confusing indent a bit.
+       The indent control file .indent.pro contained:
+  	-bad -bap -nbbo -br -ce -brs
+  	-l72  -lc72  -hnl  -nprs

+
+2003-10-02   David Anderson <davea@sgi.com>
+     * dwarfdump.c: Add -g to indicate use of older 
+       location entry code in libdwarf.  So dwarf_loclist 
+       and dwarf_loclist_n are testable.
+     * globals.h: Added use_old_dwarf_loclist flag so one
+       can choose the old dwarf_loclist() interface.
+       For testing.
+     * print_die.c: Rearranged to avoid code duplication.
+       Now supports .debug_loc fully.
+     * print_sections.c: Prints .debug_loc now.
+
+2003-09-29   David Anderson <davea@sgi.com>
+
+      * print_die.c: with -v, print 'loclist' start and
+	end addr and also a hint that DW_FORM_indirect is used.
+        No change for normal output (for now).
+
+2003-05-19   David Anderson <davea@sgi.com>
+      * dwarfdump.c call dwarf_srcfiles() to get file names
+        per cu and pass down to die print routines.
+	Removed incorrect tests for when to print ".debug_info",
+	leaving simpler test.
+      * print_die.c globals.h: print file name (from line info)
+	with DW_AT_decl_file, adding data from dwarf_srcfiles
+	to argument list of a few routines to make that possible. 
+      * print_sections.c: moved "line number info" string print so
+	it prints for -v as well as normal  line ouput.
+
+2002-10-23   Amaury Le Leyzour amaury@sgi.com
+      * print_sections.c (print_weaknames): Changed
+        DW_DLA_TYPENAME to DW_DLA_WEAK at dwarf_dealloc().
+
+2002-10-22  Tom Hughes <thh@cyberscience.com>
+      * print_sections.c: macro printing now supported.
+      * dwarfdump.c: removed erroneous dwarf_dealloc()
+        of string returned by dwarf_errmsg().
+ 
+2002-11-22  David Anderson <davea@sgi.com>
+      * dwarf_names.awk at_list.awk: Allow an name to have two 
+        spellings so the historical name preserved yet the dwarf3 
+        version is supported. First name seen is used/reported
+        by dwarfdump.
+      * dwarf.h:   DW_TAG_template_type_param(eter)
+        DW_TAG_template_value_param(eter) DW_AT_namelist_itm(s)   
+        are the ones with alternate spellings now.
+        Added Universal Parallel C TAGs/Attributes in
+	user namespace.
+      * tag_attr.c tag_attr.list tag_tree.c tag_tree.list:
+        Use the DW_TAG_template_* dwarf3 spellings.
+
+
+2002-05-08  David Anderson <davea@sgi.com>
+      * tag_attr.list dwarf.h: DW_AT_namelist_items is
+	wrong, changed to DW_AT_namelist_item
+
+2002-04-29  Stephen Clarke <stephen.clarke@superh.com>
+      * dwarfdump.c (main): #ifdef for __CYGWIN__ on open().
+
+2001-06-14  David Anderson <davea@sgi.com>
+
+      * print_sections.c: Calling the new libdwarf function
+	dwarf_get_arange_cu_header_offset() so we can print
+	the cu header offset for aranges.
+
+
+2000-07-14  Fred Fish  <fnf@ninemoons.com>
+ 
+      * configure.in (LOCATION_OF_LIBELFHEADER): Fix typo for configure
+      variable to be tested and enclose libelf/libelf.h in <>.
+      * configure: Regenerated.
+       
+2000-07-10  Fred Fish  <fnf@ninemoons.com>
+ 
+      * Makefile.in (install): Install dwarfdump.1 from $(srcdir).
+
+2000 June 12   davea@sgi.com
+  print_sections.c the DW_CFA_offset_extended print 
+	did not multiply by data-alignment factor in the
+	-v -v detailed output.
+	And the offsets used %2d when the values were
+	unsigned int, so now %2u.
+
+	And not all cfa prints of values had
+	necessarily a type to match
+	%llu or %lld where required. Depended on the size of Dwarf_Signed
+	and Dwarf_Unsigned.
+	So now explicitly use cast to the
+	right type to match the % format.
+2000 April 13 davea@sgi.com
+  print_sections.c - 1.56
+        - A single byte of zero is a perfectly legitmate null 
+          abbreviation entry          (in .debug_abbrev) 
+	 now we print those directly and avoid a warning
+          from dwarfdump
+
+  print_die.c - 1.42
+        - Explain what combo checker is doing and make it 
+	  more maintainable (and fix bug which would 
+	  not be hit, but was real enough (in combo checker),
+	  using too large a number as highest tag number).
+
+  tag_tree.list - 1.2
+        - Add valid parent/child relationships so checker 
+	  does not report valid entries as bogus.
+
+
+
+
+2000 Feb 24
+  Jason Merrill <jason@cygnus.com> noticed that gcc did
+  not like   gcc -E foo.list, so  incorporated his fix so
+  now the Makefile.in makes a link and does gcc -E _tmp.c
+
+2000 Jan 26
+  elena.demikhovsky@intel.com noticed that 3 statements in
+  print_sections.c got warnings from the compiler
+  she was using. Simple casts  (provided by her) fixed these.
+
+1999 July 21
+  davea@sgi.com 
+  print_sections changed to allow printing

+
+2007-09-04 DavidAnderson <davea42@earthlink.net>
+     * print_die.c (print_attribute): For DWARF4: DW_AT_high_pc:
+       add qualifier to value when the value is an offset from
+       DW_AT_low_pc (thus not itself a address).
+       Update the address of the FSF.

+
+2007-07-03 DavidAnderson <davea42@earthlink.net>
+     * print_sections.c (dump_block): Removed superfluous return byte from
+       printed characters. Removed unused variables.
+     * print_die.c: A little refactoring for clarity.
+     * globals.h: dwarfdump_print_one_locdesc() is now a 
+       global-to-dwarfdump function.
+     * print_frames.c: Now (with -v) prints dwarf expression bytes
+       in frame expressions readably.
+2007-07-02 DavidAnderson <davea42@earthlink.net>
+     * dwarfdump.c: Add new -R option for 'generic' register sets.
+     * dwarfdump.1: document -R, add new -x documentation.
+     * dwconf.c: Set up -R configuration. Slight revision of
+       register printing code.
+     * dwconf.h: Interface to register name printing simplified.
+     * print_frames.c: Use the simpler register name interface.
+     * dwarfdump.conf: Add new 'generic' abi for up to 1000 registers.
+
+2007-07-01 DavidAnderson <davea42@earthlink.net>

+       print a computed data alignment factor.
+2007-06-29 DavidAnderson <davea42@earthlink.net>
+     * dwarfdump.1: Corrected spelling error.
+2007-05-25 DavidAnderson <davea42@earthlink.net>
+     * dwconf.h dwconf.c: Changed field name to 
+       cf_named_regs_table_size as old name was less than clear.
+     * dwarfdump.c: Call frame table setup with
+       cf_table_entry_count not cf_named_regs_table_size. The newly
+       renamed field makes it clearer the call was wrong.
+2007-05-04 DavidAnderson <davea42@earthlink.net>
+     * print_die.c: printing of global offset of DIEs 
+       with -G is now more in the style of previous output.
+2007-04-18 Chris Quenelle <chris.quenelle@sun.com>
+     * Makefile.in:
+          - use $(srcdir) for files in source directory
+          - support running rules in parallel by
+          - use different tmp file names in different rules.
+          - use more accurate target for dwarf_names.{c,h}
+     * dwarf_names.awk: Enhance script to be able to generate either
+       #define-style headers or enum-style headers
+     * dwarfdump.c: dump most everything by default if no arguments
+       are given to dwarfdump.  This seems to be a more useful default
+       than showing nothing at all.  Also add a -G option to show
+       the (G)lobal section offset for each die within an a.out. If you
+       think you're seeing data corruption inside a .debug_info
+       section, this is a useful option to have.
+     * print_die.c: Support compressed integer blocks.  This is an
+       array (DW_FORM_block) of LEB numbers used as part of a Sun
+       extension, DW_AT_SUN_func_offsets.  Also add support for
+       a new dwarf enum DW_ATCF_xxxx. This is used in DW_AT_SUN_cf_kind.
+       Also, fix DW_AT_upper_bound so it can be a constant or a location
+       list.  DW_AT_count and DW_AT_data_member_location should also be
+       fixed eventually.
+     * print_sections.c: Changes to support zero-padding in the middle of
+       section data.  Change offset labels to be a little more clear.
+       Not sure about the get_str failure.
+     * tag_tree.list: DW_TAG_compile_unit can contain a DW_TAG_namespace
+2007-04-10 David Anderson <davea42@earthlink.net>
+     * print_reloc.c dwarfdump.c print_frames.c: Unified
+       copyright to the SGI form.  No copyright change.
+
+2007-04-06 David Anderson <davea42@earthlink.net>
+     * print_die.c (print_die_and_children): Increase static
+       depth of die stack.  Notice if it overflows and
+       print error.
+2007-02-23 David Anderson <davea42@earthlink.net>
+     * print_reloc.c: 2 lines added (long) cast in printf
+       and made %3ld instead of %3d to fix compiler warning.
+     * print_frames.c:  newline was missing from the output.
+       Thanks to Chris Quenelle for noticing.
+2007-02-20 David Anderson <davea42@earthlink.net>
+     * print_frame.c (print_frame_inst_bytes): Fixed
+       an off by one error  (several places)
+       when printing dwarf expressions and added commentary about it.
+       Thanks to Julian Seward for pointing out it was off by one.
+     * dwarfdump.c (print_error): added fflush of stdout, stderr
+       where we are going to exit right away anyway.

+        0x%  so that zero prints with leading 0x consistently.

+      * print_static_vars.c, print_static_funcs.c, print_strings.c,
+        print_locs.c, print_pubnames.c, print_lines.c, print_ranges.c,
+        print_abbrevs.c, print_macros.c, print_types.c, print_weaknames.c,
+        print_aranges.c: Moved the print_* functions from print_sections.c
+        into individual sourcefiles.
+      * Makefile.in: Now lists the new sourcefiles.
+      * print_sections.c: Deleted code moved to individual sourcefiles.
+        Added code to try to find the name from a DW_AT_abstract_origin 
+	DIE when a subprogram DIE itself has no DW_AT_name;
+      * dwarfdump.c: Remove unused local variables. Use DWARFDUMP_VERSION
+        #define to set version string.
+      * tag_tree.c: Fix && || problem with parentheses.
+      * tag_attr.c: Fix && || problem with parentheses.
+      * print_frames.c: Moved the 'print_frames' function itself from
+        print_sections.c to here.
+2009-03-17: David Anderson <davea42@earthlink.net>
+      * globals.h: Created predicate function
+        should_skip_this_cu() predicate function.  Eliminating
+        code duplication.
+      * print_frames.c: Fix a hex value output to have a leading
+        0x as all hex values should (when printed).
+      * print_sections.c: Call should_skip_this_cu(), which
+        replaces duplicate code.
+        Fix the arange print: now the hex value has a leading 0x
+        as all hex values should.  get_proc_name() had local
+        variable funcnamefound initialized incorrectly, now is
+        set to 0 as it should be. get_nested_proc_name()
+        now initializes string buffers. get_fde_proc_name()
+        now initializes its string buffer.  Surprisingly
+        things worked adequately before in spite of the errors.
+      * dwarfdump.c: Call should_skip_this_cu(). Implementation
+        of that new function is in this source file.
+2009-03-16: David Anderson <davea42@earthlink.net>
+      * print_frames.c:DW_CFA_restore output had a spurious newline.
+        Removed 2 pointless blank lines an initialized 2 local variables.
+      * print_sections.c: Removed a pointless redeclaration of a function
+        in libdwarf.h. check_info_offset_sanity() was missing a
+        return statement in one place, which could lead to spurious
+        extra (and silly) error text.
+2009-03-09: David Anderson <davea42@earthlink.net>
+      * print_die.c: Make a comment easier to understand.
+2009-02-28: David Anderson <davea42@earthlink.net>
+      * Makefile.in: add tmp-*.tmp to the 'clean' rule.
+2009-02-17: David Anderson <davea42@earthlink.net>
+      * print_sections.c,print_die.c,tag_common.c,print_frames.c: C99
+        in-line declarations and // comments are not intended here,
+        this removes a few that were introduced accidentally.
+2009-02-16: David Anderson <davea42@earthlink.net>
+      * Makefile.in: Removed some use of awk and
+        simplified some shell scripting here.
+        renamed temp files, no longer named with
+        underbars, they uniformly start with 'tmp-'.
+      * print_sections.c: Added the new argument required
+        by the updated dwarf_names.c functions argument lists.
+      * tag_tree_ext.list: List 'common extensions' 
+        of tag->tag relationships.
+      * tag_attr_ext.list: List 'common extensions' 
+        of tag->attr relationships.
+      * print_die.c: New 'common extension' tables used
+        for checking tag->tag and tag->attr relationships
+        unless turned off with -C.
+      * dwarf_names.awk: Removed tabs so generated names.c not so
+        spread out. Added argument to the generated functions so
+        tag_tree.c, tag_attr.c can use these generated functions nicely.
+      * dwarfdump.c: Adding -C option, which exposes
+        some 'common extensions' of dwarf uses as DWARF CHECK
+        (-ka) warnings.  By default these extensions not reported
+        as warnings.  
+      * tag_tree.c: Now generates base and extensions tables.
+        Code in common with tag_attr.c is in tag_common* files.
+      * tag_attr.c: Now generates base and extensions tables.
+        Code in common with tag_tree.c is in tag_common* files.
+      * tag_common.c, tag_common.h: New files with the common
+        data extracted from tag_tree.c and tag_attr.c
+      * globals.h: global flag added for -C.
+      
+2009-02-14: David Anderson <davea42@earthlink.net>
+      * configure.in: Define --enable-nonstandardprintf
+      * config.h.in: new #undef HAVE_NONSTANDARD_PRINTF_64_FORMAT
+      * configure: Regenerated.
+      * config.guess, config.sub: Latest version from GNU.
+      * Makefile.in: Referenced configure variable to avoid
+        irritating message at configure time.
+      * README: document --enable-nonstandardprintf
+      * print_sections.c, print_die.c, print_reloc.c, dwarfdump.c,
+        dwconf.c, print_frames.c: Use libdwarf.h DW_PR_ printf macros
+        for for better portability.
+2009-02-13: David Anderson <davea42@earthlink.net>
+      * print_sections.c: Ensure we are checking line table header
+        correctness whichever line-table-print code is being used.
+        Allow ARM line header table (which has a bug) to be used.
+      * dwarfdump.c: Print lines_result total with checking on.
+      * globals.h: Add lines_result global to count line botches.
+2009-02-11: David Anderson <davea42@earthlink.net>
+      * print_sections.c, print_die.c: DWARF_CHECK_ERROR*
+        macros now get the count struct passed in.
+      * tag_tree.c, tag_attr.c: Add a comment in the output
+        identifying the output as generated code and
+        with the generation date/time inserted.
+      * globals.h: Accept the struct in DWARF_CHECK_ERROR*
+        macros so we can update the error count in the macro.
+2009-01-31: David Anderson <davea42@earthlink.net>
+      * Makefile.in: Remove compilation of _tag_attr_table.c
+        and _tag_tree_table.c as those are #included in
+        print_die.c, not separately compiled.
+      * print_frames.c: A formerly-static function now called
+        from another file, so declare it here.
+      * print_sections.c: Improve the printing of the .debug_loc
+        section.
+      * print_die.c: A  couple of errors were missing their error
+        count increment.
+      * tag_attr.list tag_tree.list: Some normal relationships
+        were left out of the tables: fixed now.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+December 13, 2011
+  Now prints missing line table column number as 0 (now
+  matching the DWARF spec), the previous
+  practice of printing -1 was always wrong.
+  And prints the DWARF3/4 new line table fields (when present).
+October 29, 2011
+  Added support for printing .debug_types (type unit) data.
+October 26, 2011
+  Added new features to Makefile.in and documented in README
+  how to build dwarfdump with headers or libraries in
+  non-standard places.
+October 23, 2011
+  By default the various places with string option values
+  and file paths all use URI transformation on input and
+  if the transformation does anything at all dwarfdump reports
+  the input and transformed strings.  This makes it easy
+  to deal with strings and expressions and file paths
+  that are difficult to express in a shell (or that getopt
+  mangles). Options  -q and -U give you  control over this process.
+October 07, 2011
+  The -x abi=mips  frame register abi in dwarfdump.conf is now
+  usable with modern MIPS objects as well as old IRIX objects.
+  There are other mips-* frame register setups described
+  in dwarfdump.conf for anyone testing that nothing new has
+  been added that conflicts with old IRIX/MIPS frame generation.
+June 04, 2011
+  Error checking is now distinct from section printing, making
+  error checking (the -k options) much easier to work with on
+  large objects.
+  So compiler-created errors can be found, the error reporting
+  now prints context information.
+March 29, 2011
+  Added many new correctness tests.  Changed the format of
+  various items (line data prints in a more compact form, numbers
+  are more uniformly hexadecimal fixed length where that makes sense).
+  All the source files are uniformly indented to a multiple of 4
+  characters and all intent-tabs in the source have been removed.
+  Major logic changes involved changing error-reporting to be
+  more detailed and adding new tests for incorrect DWARF.
+  Now reports error summary by the compiler name, not just overall.
+January 26, 2010
+  Changed the default frame-data register names from MIPS to
+  a generic set of registers.  
+  Try  '-x abi=mips' to get the traditional old MIPS register
+  naming.
+June 22, 2009
+  Added the -S option to dwarfdump.
+June 10, 2009
+  Moved the gennames.c code to libdwarf.
+May 4, 2009
+  Replaced awk source-generation of certain functions
+  with new gennames.c code.
+  Now we can print an object with an address_size that
+  varies by compilation unit.
+April 4, 2009
+  Corrected aspects of the frame-printing by ensuring we pass
+  all the information libdwarf needs for fully consistent behavior.
+  Three newly defined libdwarf calls calls made to ensure
+  that better behavior (specifically having dwarfdump consistently
+  recognize when registers are the cfa, undefined-value or same-value
+  pseudo registers). Updated dwarfdump.conf to set these same
+  things consistently.
+Mar 22, 2009
+  The -f and -F flags no longer also imply -i (it just
+  did not make sense to tie them (cannot recall why
+  it might have been tied before).
+Mar 20, 2009
+  Moved print_* functions from print_sections.c to individual
+  source files. Hopefully making the code a bit easier
+  to read.
+Feb 16, 2009
+  Added the -C option.  It is a sort of 'pedantic' option
+  as it turns on warnings about certain commonly used
+  non-standard tag->tag and tag->attr relationships.
+  Added the tag_attr_ext.list  tag_tree_ext.list files which
+  define the 'common use' extensions.
+Feb 14, 2009
+  Added configure option --enable-nonstandardprintf
+  which makes it easy to get printf of Dwarf_Unsigned (etc)
+  types correct even for non-standard compilers.
+December 30, 2008
+  Now we print the .debug_ranges section (with -N) 
+  and the data for DW_AT_ranges (with -i).
+December 8, 2008
+  The -M option now causes printing of FORM details.
+  And -v adds details about abbreviation 'indexes' into
+  an abbreviation table (.debug_abbrev)
+  providing more detail for folks debugging or
+  improving their understanding of DWARF data.
+April 9, 2008
+  Added -H  <num>  to limit the number of compilation-units/FDEs
+  dwarfdump prints in one run.  Added -n to eliminate function-name
+  printing in .debug_frame output (with a large-enough debug_info
+  section function-name printing is too slow). The function name
+  printing will be fixed in another release.
+December 8, 2007
+  Had to add an ugly configure conditional as libelf has
+  unconditional use of off64_t in recent libelf.h
+July 3, 2007
+  Now with -v dwarf expression blocks in frame operations
+  are printed expanded out.
+July 2, 2007
+  Added a new abi -x abi=general usable for any cpu with
+  up to 1000 registers.
+May 7, 2007
+  Sun Microsystems contributes new dwarf.h extensions and a new -G option
+  to dwarfdump -i (so one can see the 'global' offset to DIEs).
+  Thanks to Chris Quenelle of Sun.
+April 17, 2006
+  New -x name=<conf file> -x abi=<abiname> and configuration file
+  enable sensible printing of a wide range of .debug_frame eh_frame
+  correctly without recompiling dwarfdump or touching libdwarf.h or
+  dwarf.h.
+March 29, 2005
+  Now handles DWARF3. For non-MIPS objects, the list of register
+  names in print_sections.c is not appropriate, #define
+  DWARFDUMP_TURN_OFF_MIPS_REG_NAMES to turn off the MIPS names.
+December 1, 2005
+  Added new DWARF3 TAGs and ATtributes to the -k lists,
+  clarified the -k reporting, and made the build more robust
+  in the face of errors in the *.list relationship-spec-files.
+
+August 1, 2005
+  Now print_die.c deals with long loclists without a coredump.
+  Added esb.h esb.c (and testesb.c for testing) to encapsulate 
+  getting space for possibly-long strings.
+  Now print_die.c uses snprintf() not sprintf (hopefully this
+  will not inconvenience anyone, snprintf() has been available
+  on most systems for years now).
+  Altered print of location lists a little bit - for better appearance.
+
+July 15, 2005
+  Now completely frees all allocated memory. Various
+  routines were not calling dealloc() code and
+  new libdwarf dealloc routines are now used where those
+  are needed.
+
+  Now prints DWARF3 .debug_pubtypes section (with -a or -y).
+  The .debug_pubtypes section and  SGI-specific .debug_typenames
+  are equvalent so they are treated alike.
+
+Mar 21, 2005
+  The -f flag now prints only .debug_frame data. The .eh_frame section
+  (GNU exceptions data) now prints with -F (not -a). 
+  Printing gcc 3.3 or 3.4 .eh_frame with zR augmentation
+  does not work at this time, so do not use -F
+  to print such an object.
+  The line section print now prints a CU-DIE offset for each such DIEs
+  line information.   This makes it much easier to correctly associate
+  -l (or -v -l) output with -v -v -l when debugging a faulty
+  linetable in an executable.

+I would prefer you try using ../dwarfdump2, not this source.
+If you  must use this for some reason, could you let me know why?
+Thanks.
+
+To build dwarfdump, first build libdwarf in the neighboring
+directory then type
+	./configure
+	make
+
+Installation is a bit primitive.
+      sudo make install
+may or may not work.   
+Some or all of the following might be required on Unix or Linux or MacOS:
+      sudo mkdir -p /usr/local/share/man/man1/
+      sudo mkdir -p /usr/local/lib
+      sudo mkdir -p /usr/local/bin
+Then retry the 'sudo make install' and (if necessary) try
+      sudo chmod a+x /usr/local/bin/dwarfdump
+      sudo chmod a+r /usr/local/share/man/man1/dwarfdump.1
+      sudo chmod a+r /usr/local/lib/dwarfdump.conf
+You don't really need the dwarfdump.1 man page,
+but you might as well have it. If the man page is not visible
+with 'man dwarfdump' try  'man manpath' for hints.
+
+If you don't need others using dwarfdump on your computer,
+just 
+    cp dwarfdump $HOME/bin/dwarfdump 
+(by convention many people put personal executables in $HOME/bin
+and fix up $PATH to refer there) which suffices as 'installation'.
+Also   
+    cp dwarfdump.conf $HOME 
+
+To use dwarf or libdwarf, you may want to install dwarf.h
+and libdwarf.h somewhere convenient.
+You can just copy those two headers to /usr/local/include by hand
+(or anywhere, really, that you have permission to copy to)
+(you may need to use -I/usr/local/include on compile lines
+to reference them there, but see below on configure and make).
+
+Notice that dwarf_names.c and dwarf_names.h are supplied by
+the release though the Makefile can and may rebuild them.
+Some users find it difficult to get a reliable awk(1) program,
+so for them these prebuilt versions may be useful.
+
+If your headers or libelf/libdwarf are not in the expected places,
+use the make command line to add flags and include directories.
+For example
+  ./configure
+  PREINCS="-I /usr/local/include" POSTINCS="-I /home/x/include"  make
+PREINCS content is inserted before CFLAGS as make(1) is running.
+POSTINCS content is added after the CFLAGS value.
+
+To set LDFLAGS,
+do so at configure time, for example:
+  ./configure LDFLAGS="-L /some/dir"
+And/or use PRELIBS and/or POSTLIBS at 'make' time similar to the use
+of PREINCS and POSTINCS.
+
+If the libdwarf directory
+has both libdwarf.so and libdwarf.a, the libdwarf.so
+will be picked up and
+  "./tag_tree_build: error while loading shared libraries:
+        libdwarf.so: cannot open shared object file:  
+        No such file or directory"
+will probably result.
+Either: remove libdwarf.so  and rebuild or set
+the environment variable LD_LIBRARY_PATH to  the directory 
+containing the .so or use LDFLAGS to set rpath (see just below).   
+It is perhaps simpler to ensure that the libdwarf directory
+only has an archive, not  a shared-library.
+But sometimes one wants a shared library.
+In that case
+one can set ld's -rpath on the gcc command line like this:
+    LDFLAGS="-Wl,-rpath=/some/path/libdir"
+so the shared library can be found at run time automatically.
+
+The same problem may arise with libelf, and the same approach
+will solve the problem.

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]

+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+.TH DWARFDUMP
+.SH NAME
+dwarfdump \- dumps DWARF debug information of an ELF object
+.SH SYNOPSIS
+.B dwarfdump [options] \f2objectfilename\fP
+.SH DESCRIPTION
+The 
+.B dwarfdump
+command prints or checks DWARF sections as requested by specific options.
+With no options (but with the required \f2objectfilename\fP ) 
+all sections print (but some sections cannot be printed independently
+safely, so those are only printed at offsets where the .debug_info section
+refers to those sections).
+.PP
+As of June 2011 the printing options and the checking options
+are mutually exclusive (if checking options are selected 
+the section details are not printed).   When errors are encountered
+dwarfdump does attempt to print sufficient context so that
+one can understand exactly where the error is in the DWARF.
+This change makes checking really large object files
+much easier.
+.PP
+The format is intended to be human readable.
+If a script is to parse the output, the
+.B \-d
+option is useful.
+.PP
+Not all sections actually exist in any given object file.
+.PP
+The format may change from release to release, so it is
+unwise to depend too heavily on the format.
+.PP
+Frame information (.debug_frame and .eh_frame) is heavily
+dependent on the ABI/ISA of the object file.  
+By default we use a generic set of register names
+handling up to 100 registers named r0-100.
+The '-R' option uses a built-in generic register name set
+handling up to 1200 registers named r0-r1199.
+The '-x abi=<abi>'
+description below shows how to name an abi and use that to guide
+the -f or -F processing.
+Unless the cpu for the object file being dumped has many registers,
+do not use -R or -x abi=generic as those can be needlessly 
+slow dumping frame sections. Instead, use the correct
+abi (if it exists in dwarfdump.conf) or a generic such
+as -x abi=generic100 or -x abi=generic500.
+To get MIPS/IRIX register names names and call the old version 2 libdwarf
+frame interface use the option '-x abi=mips'.
+Without '-R' or '-x abi=<abi>' dwarfdump ignores
+the dwarfdump.conf file and uses compiled-in generic set of
+register names.
+If no '-x name=<path>' is given, dwarfdump
+looks for "./dwarfdump.conf", "$HOME/.dwarfdump.conf", "<install-prefix>/lib/dwarfdump.conf" and takes the first it finds.
+If one or more '-x name=<path>' is given the last of these is
+used and all other such files are ignored.
+.PP
+Some -k (checking) options print so-called harmless errors.
+These are compiler errors that do not cause any
+known problem and are only detected inside libdwarf itself.
+These are difficult to properly report in dwarfdump and
+any error strings may not appear close to the time the
+error was encountered.
+.SH URI STYLE INPUT STRINGS
+.PP
+The <objectfilename> and the options taking name strings look for URIs and
+translate the URI strings to characters by default
+(see -x, -c<compiler name>, -S, -u).
+So any single % character is treated as if the following two
+characters are hex digits representing the underlying true character.
+Various characters are meaningful to shells (such as bash or sh) 
+and to getopt (such as the space character) 
+If the URI translation does anything it prints the before and after
+of the URI translation on standard output, so inspection of the first
+lines of output will show if URI did anything.
+The actual options themselves are assumed to be non-URI.
+So in the option '-cS&T' the -c portion must be non-URI, but the
+& character might cause input issues so '-cS%26T' could be used instead.
+To actually input a single % character (in a name, for example), 
+double it to %% on the command line.
+.PP
+Options -U (turning off URI interpretation) and -q (making finding
+URI sequences silent) give finer control of URI interpretation.
+PP
+As an example, to get a string'a b' make the string 'a%20b'
+(here the quote  (') is for exposition not part of the string, though
+quote is certainly problematic in a name).
+Instead of escaping " quotes in the string,  type %25, as in
+   'a "b'  should be typed   'a%20%25b'
+Any characters can be typed in URI style, not just characters
+which are problematic to the shell or getopt.
+We strongly suggest you not type URI-style characters where
+such are not needed or use
+the % character itself in command line strings unless you must.
+.SH PRINTING OPTIONS
+.TP
+.B \-a
+Print each section as independently as possible. Sections that
+can safely be printed independently (like .debug_abbrev)
+have relevant info printed in the report (sometimes dependent
+on -v).
+
+.TP
+.B \-b
+Print the .debug_abbrev section. Because the DWARF specfications
+do not rule out garbage data areas in .debug_abbrev (if they are not
+referenced from .debug_info) any garbage bytes can result in
+this print failing.
+
+.TP
+.B \-c
+Print locations lists.
+
+.TP
+.B \-f
+Print the .debug_frame section.
+.TP
+.B \-F
+Print the .eh_frame section.
+
+.TP
+.B \-i
+Print  the .debug_info section.
+
+.TP
+.B \-l
+Print the .debug_info section and the associated line section data.
+
+.TP
+.B \-m
+Print the .debug_macinfo section.
+
+.TP
+.B \-N
+Print .debug_ranges section.  Because the DWARF specfications
+do not rule out garbage data areas in .debug_ranges (if they are not
+referenced from .debug_info) any garbage bytes can result in
+this print failing.
+
+.TP
+.B \-p
+Print the .debug_pubnames section.
+
+.TP
+.B \-r
+Print the .debug_aranges section.
+.TP
+.B \-s
+Print .debug_string section.
+
+.TP
+.B \-ta
+Print the IRIX only sections .debug_static_funcs and .debug_static_vars.
+
+.TP
+.B \-tf
+Print the IRIX only section .debug_static_funcs.
+.TP
+.B \-tv
+Print the IRIX only section .debug_static_vars.
+
+.TP
+.B \-w
+Print the IRIX-only .debug_weaknames section.
+
+.TP
+.B \-y
+Print the .debug_pubtypes section (and .debug_typenames,
+an SGI IRIX-only section).
+
+.PP
+Having dwarfdump print relocations may help establish whether
+dwarfdump understands any relocations that might exist.
+
+.TP
+.B \-o    
+Print all relocation records as well as we can manage.
+.TP
+.B \-oi  
+Print .rel*debug_info relocations.
+.TP
+.B \-ol  
+Print .rel*debug_line relocation.
+.TP
+.B \-op  
+Print .rel*debug_pubnames relocation.
+.TP
+.B \-oa  
+Has no effect.
+.TP
+.B \-or  
+Print .rel*debug_aranges relocations.
+.TP
+.B \-of  
+Print .rel*debug_frame relocations.
+.TP
+.B \-oo  
+Print .rel*debug_loc relocations.
+.TP
+.B \-oR  
+Print .rel*debug_ranges relocations.
+
+.TP
+.B \-g
+Normally used only for testing libdwarf, this tells dwarfdump to
+print .debug_info and use an older dwarf_loclist() interface
+function (a function that cannot handle all current
+location lists).
+.TP
+.B \-V  
+Print a dwarfdump date/version string and stop.
+
+.SH CHECKING OPTIONS
+.TP
+.B \-cg 
+Restricts checking to compilers whose
+producer string starts with 'GNU'
+and turns off -cs .
+
+.TP
+.B \-cs
+Restricts checking to compilers whose
+producer string starts with 'SN'
+and turns off -cg .
+.TP
+.B \-cname
+Restricts checking to compilers whose
+producer string contains 'name' (not case sensitive).
+The 'name' is read as a URI string.
+
+.TP
+.B \
+-ka        : Turns on all checking options except -kxe (-kxe might
+             be slow enough one mignt not want to use it routinely.)
+
+.TP
+.B \
+-kb        : Checks for certain abbreviations section errors when reading
+             DIEs.
+.TP
+.B \-kc 
+Checks for errors in constants in debug_info.
+.TP
+.B \-kd 
+Turns on full reporting of error totals per producer.
+(the default shows less detail).
+.TP
+.B \-ke 
+Turns on reading pubnames and checking for fde errors.
+.TP
+.B \-kf 
+Turns on checking for FDE errors.
+.TP
+.B \-kF 
+Turns on checking for line table errors.
+.TP
+.B \-kg 
+Turns on checking for unused gaps in .debug_info (these
+gaps are not an error, just a waste of space).
+
+.TP
+.B \-ki 
+Causes a summary of checking results per compiler (producer)
+to be printed at the end.
+.TP
+.B \-kl 
+Turns on locations list checking.
+.TP
+.B \-km 
+Turns on checking of ranges.
+.TP
+.B \-kM 
+Turns on checking of aranges.
+.TP
+.B \-kr
+Turns on DIE tag-attr combinations checking.
+.TP
+.B \-kR 
+Turns on reading DIEs and checking for forward declarations
+rom DW_AT_specification attributes.
+(which are not an error but can be a source of inefficiency
+for debuggers).
+.TP
+.B \-ks 
+Turns on extra reporting for some DIE errors checking detects .
+.TP
+.B \-kS 
+Turns on checking DIE references for circular references.
+.TP
+.B \-kt 
+Turns on tag-tag combinations checking.
+.TP
+.B \-kx 
+Turns on check_frames.
+.TP
+.B \-kxe 
+Turns off basic check_frames and turns on extended frame checking.
+.TP
+.B \-ky 
+Turns on type_offset, decl_file checking,
+
+.SH OPTION MODIFIERS
+
+.TP
+.B \-C 
+Normally when checking for tag-tag or tag-attribute combinations
+both the standard combinations and some common extensions are allowed.
+With -C the extensions are taken out of the allowed class of combinations.
+
+.TP
+.B \-d
+When printing DIEs, put all the attributes for each DIE on the same (long)
+line as the TAG.  This makes searching for DIE information
+(as with grep) much simpler as the entire DIE is on one line.
+
+.TP
+.B \-D
+Turns off the display of section offsets and attribute values in printed output.
+So the .debug_info output isjust TAGs and Attributes.
+For pubnames (and the like) it removes offsets from the output.
+For locations lists it removes offsets from the output, but that
+is useless since the attribute values don't show so neither does
+the location data.
+
+.TP
+.B \-e
+Turns on truncation of attribute and tag names. For example
+DW_TAG_foo  becomes   foo .    Not compatible with
+checking, only useful for printing DIEs.
+
+.TP
+.B \-G
+When printing, add global offsets to the offsets printed.
+
+.TP
+.B \-H number 
+When printing or checking .debug_info, this terminates
+the search after 'number' compilation units.  When printing
+frame information this terminates the FDE reporting 
+after 'number' FDEs and the CIE reporting (which occurs if one adds -v)
+after 'number' CIEs.  Example   '-H 1'
+
+.TP
+.B \-M 
+When printing, this means one want to have the FORM show for each attribute.
+If a -v is also added (or more than one) then details of any form indirection
+are also shown.
+
+.TP
+.B \-n 
+When printing frames, this turns off the search for function names.
+In a really large object the search can take more time than
+one wants to wait, so this avoids the search.
+
+.TP
+.B \-Q 
+Suppresses section data printing (set automatically with a checking option).
+
+.TP
+.B \-R 
+When printing frames for ABIs with lots of registers, this allows
+up to 1200 registers to be named (like R999) without choosing an ABI
+with, for example '-x abi=ppc'
+
+.TP 
+.B \-v
+Increases the detail shown when printing.
+In some sections, using more -v options
+will increase the detail (one to three are useful) or may
+change the report to show, for example, the actual
+line-data-commands instead of the resultant line-table.
+
+.SH SELECTIVE ENTRY PRINTING
+
+.PP
+These -S options stand alone and basic print information about the compilation
+unit and DIE where the string(s) appear.
+At most one of each of the following is effective (so for example
+one can only have one 'match', but one can 
+have a 'match', an 'any', and a 'regex').
+Any -S causes the .debug_info section to be inspected.
+No checking options or printing options should be supplied with -S.
+
+.TP
+.B \-S match=string
+When printing DIEs
+for each tag value or attribute name that matches 'string' exactly
+print the compilation unit information and its section offset.
+Any CU with no match is not printed.
+The 'string' is read as a URI string.
+.TP
+.B \-S any=string   
+When printing DIEs
+for each tag value or attribute name that contains 'string'
+somewhere in the tag or attribute (case insensitive)
+print the compilation unit information and its section offset.
+Any CU with no match is not printed.
+The 'string' is read as a URI string.
+.TP
+.B \-S regex=string 
+When printing DIEs
+for each tag value or attribute name where the 'string' reqular
+expression matches print the compilation unit information
+and its section offset.
+Any CU with no match is not printed.
+The 'string' is read as a URI string.
+
+.PP
+The string cannot have spaces or other characters which are
+meaningful to getopt(3) and the shell will strip off quotes and
+other characters.
+So the string is assumed to be in URI style and is translated.
+In other words, to match 'a b' make the -S string 'a%20b'
+Instead of escaping " quotes in the string,  type %25, as in
+   'a "b'  should be typed   'a%20%25b'
+(the ' are for exposition here, not part of the strings).
+Any characters can be typed in URI style, not just characters
+which are problematic to the shell or getopt.
+.PP
+The -S any= and -S regex= options are only usable
+if the library functions required are found at configure time.
+.PP
+The -W option is a modifier to the -S option, and
+increases the amount of output -W prints.
+Now we show the -W in context with a -S option.
+
+.TP
+.B \-S match=string1 -W
+Prints the parent tree and the children tree for the
+DIEs that -S matches.
+
+.TP
+.B \-S match=string2 -Wp
+Prints the parent tree for the DIEs that -S matches.
+
+.TP
+.B \-S match=string3 -Wc
+Prints the parent tree for the DIEs that -S matches.
+
+.SH OTHER OPTIONS
+
+.TP
+.B \-# number 
+This option controls internal debugging output,
+higher numbers mean more debug actions. See the source code.
+
+
+.TP
+.B \-x name=/p/a/t/h.conf 
+The file path given is the name of a file assumed to be
+a dwarfdump.conf-like file.
+The file path is read as a URI string.
+
+.TP
+.B \-x abi=ppc  
+Selects the abi (from a dwarfdump.conf file) to be used in
+printing frame information (here using ppc as an example).
+The abi is read as a URI string.
+
+.TP
+.B \-P 
+When  checking this adds the list of compilation-unit names
+seen for each producer-compiler to the printed checking results.
+.TP
+.B \-q
+When a URI is found and translated while reading
+the command line, be quiet about
+the URI translation. That is,  don't print the
+original and translated option strings.
+
+.TP
+.B \-E 
+Turns on printing object-internal header data for some
+systems (for Unix/Linux does nothing).
+
+.TP
+.B \-u cuname 
+Turns on selective printing of DIEs (printing like -i).
+Only the DIEs for a compilation unit that match the
+name provided are printed.
+If the compilation unit is ./a/b/c.c
+the 'cuname' you provide should be c.c as the characters
+through the final path-separating / are ignored.
+If 'cuname' begins with a / then the entire name string
+of a compilation unit must match 'cuname'.
+The 'cuname' is read as a URI string.
+
+.TP
+.B \-U
+Turn off the URI interpretation of the command line
+strings entirely.  Must be be on the command line before
+any URI strings encountered to be fully effective.
+
+.TP
+.B \-z
+No longer suported.

+.SH NOTES
+In some cases compilers use DW_FORM_data1 (for example)
+and in such cases the signedness of the value must be taken
+from context. Rather than attempt to determine the
+context, dwarfdump prints the value with both signednesses
+whenever there is ambiguity about the correct interpretation.
+For example, 
+"DW_AT_const_value           176(as signed = -80)".
+For normal DWARF consumers that correctly and fully
+evaluate all attributes there is no ambiguity of signedness:
+the ambiguity for dwarfdump is due to dwarfdump evaluating
+DIEs in a simple order and not keeping track of much context.
+.SH BUGS
+Support for DWARF3 is being completed but may not be complete.

+David Anderson: December 2006
+The code in the dwarfdump directory is (if you look
+in each file) covered by the GPL (not the LGPL).  The
+DWARFDUMPCOPYRIGHT file, though, said (before December 24,
+2006) the copyright is LGPL.  There is no doubt in my (David
+Anderson) mind that the intent was always that dwarfdump be
+GPL and the copyright markings in each file are correct.
+
+There are three files marked with the LGPL: tag_tree.list
+tag_attr.list acconfig.h.  These markings are left as is and
+these are are therefore LGPL files.
+
+The DWARFDUMPCOPYRIGHT file now (Dec 24 2006) has both
+copyrights and an explanation of where each applies.
+
+
+
+-------------------------------------------
+The text present for years, thru Dec 23, 2006:
+The files:
+	dwarfdump.c
+	and all the .h and .c files in this implementation of
+	dwarfdump are copyrighted according to the file
+	DWARFDUMPCOPYRIGHT.

+      * configure: Regenerated with autoconf 2.64.
+2009-11-24  DavidAnderson <davea42@earthlink.net>
+      * tag_common.h: Updated 'standard tag table row' and
+        tag table column maximums now the DWARF4 entries are
+        in the .list files. Removed dos 'CR' characters at line ends.
+      * tag_tree.list, tag_attr.list: Added various
+        DWARF4 entries and added DW_TAG_enumeration_type
+        under DW_TAG_union_type.
+2009-11-17  DavidAnderson <davea42@earthlink.net>
+      * dwarfdump.1: Document the -u option more fully.
+      * print_die.cc: Check for both info_flag and
+        cu_name_flag to decide when to print DIEs.
+2009-10-12  DavidAnderson <davea42@earthlink.net>
+      * dwarfdump.cc: Updated dwarfdump version string to today.
+2009-09-30  DavidAnderson <davea42@earthlink.net>
+      * dwarfdump.cc: Added globals for aranges checking and
+        to print the resulting error count.
+      * print_aranges.cc: Added checking that all 3 ways
+        of computing a cu_die_offset from an arange get
+        the same offset (checked with -r -ka).
+      * print_frames.cc: DW_CFA_cfa_offset_extended_sf 
+        corrected to DW_CFA_offset_extended_sf.
+        The print_frames code now uses the dwarf_get_CFA_name() call
+        from libdwarf to print frame operation names.
+      * globals.h: New function SpaceSurround() so we can use
+        dwarf_get_CFA_name concisely in print_frames.cc. 
+        Added aranges_result
+        and check_aranges so print_aranges.cc can use them.
+2009-09-01  DavidAnderson <davea42@earthlink.net>
+      * tag_tree.list:  We add

+      * naming.cc,naming.h: New files that implement the

+        libdwarf to get the names of the TAGs, FORMs, etc..
+      * gennames.cc: This file has moved to libdwarf, no longer

+        the name strings now.
+2009-05-10: David Anderson <davea42@earthlink.net>
+      * dwarfdump.cc: updated DWARF_VERSION string.
+      * print_frames.cc: When using the older frame register
+        interface with -v, suggest use of -R instead of erroring off
+        or segfaulting in dwarfdump.
+2009-05-07: David Anderson <davea42@earthlink.net>
+      * Makefile.in: The dwarf_names* files are all
+        generated by C++ now, so clean cleans them out.
+2009-05-04: David Anderson <davea42@earthlink.net>
+      * dwarf_names.awk, at_list.awk: deleted. gennames.cc replaces these.
+      * common.h, common.cc: Extracted simple utility routines

+      * gennames.cc: New code emitting string 'get name' source.
+      * print_frames.h: Adding new address_size argument to 
+        get_string_from_locs().
+      * dwarf_names_new.h: Deleted from svn, this is generated.
+2009-04-03: David Anderson <davea42@earthlink.net>
+      * Makefile.in: clean up 'clean' and 'distclean'
+        so that distributed files are not cleaned out by 'clean' 
+        and all generated files (even those shipped in distribution)
+        are cleaned out by distclean.
+      * fderegs.h: New class that reads interface 2  and 3 libdwarf
+        and reduces to a common interface to simplify print_frames.cc
+        It also radically speeds up frame printing when there are
+        large numbers of registers in the ABI by using a different
+        libdwarf interface than before.
+      * print_frames.cc: Uses FdeRegs class to simplify and unify
+        getting frame registers. Uses a different libdwarf interface
+        to speed up register acquisition.
+      * dwarfdump.cc: Added calls to libdwarf to specify the correct
+        'same value' and 'undefined value' pseudo-register numbers.
+      * dwarfdump.1: Amplified -R and -x abi= documentation.
+      * dwconf.cc: Added comments and deleted a few duplicated lines.
+      * dwarfdump.conf: Added generic500 generic100 abis.
+        Now all ABIs have same_val_reg: and undefined_val_reg:
+        defined.
+      * dwarf_names_enum.h: delete dwarf_names_enum.h from svn, 
+        it is a generated file.
+2009-03-29: David Anderson <davea42@earthlink.net>
+      * Makefile.in: References dieholder.h and srcfilesholder.h.
+      * dieholder.h: New: Implements DieHolder class.
+      * srcfilesholder.h: New: Implements SrcfilesHolder class.
+      * print_aranges.cc: Use SrcfilesHolder and DieHolder classes.
+      * print_sections.cc:  The dwarf_names_print_on_error flag
+        is now a bool.
+      * globals.h: Some interfaces use SrcfilesHolder and DieHolder classes.
+        Some values now external so they are visible (used in print_infos()
+        which is now in print_die.cc.
+	The dwarf_names_print_on_error flag is now a bool.
+      * print_lines.cc: Use SrcefilesHolder and DieHolder classes.
+      * dwarfdump.cc: If should_skip_this_cu() we need to
+        continue; and this fixes the omission of the continue.
+        print_infos() moved out of here.
+      * print_die.cc: Moved print_infos() to here. Interfaces use
+        DieHolder and SrcfilesHolder classes now.
+      * print_locs.cc: Add a new -v (verbose) output field so
+        entries can be matched to .debug_info output.
+      * dwarf_names.awk: The 'print on error' arg is now a bool.
+        Removed a superfluous space from the generated code.
+      * print_macros.cc: A ) was missing from the output.
+      * tag_tree.cc,tag_attr.cc: The 'print on error' argument
+        of the generated code (and all uses) is now a bool.
+2009-02-28: David Anderson <davea42@earthlink.net>
+      * Created a new source base based on dwarfdump.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+  Now prints missing line table column number as 0 (now
+  matching the DWARF spec), the previous
+  practice of printing -1 was always wrong.
+  And prints the DWARF3/4 new line table fields (when present).
+October 29, 2011
+  Added support for printing .debug_types (type unit) data.
+October 26, 2011
+    Added new features to Makefile.in and documented in README
+    how to build dwarfdump with headers or libraries in
+    non-standard places.    
+October 23, 2011
+    By default the various places with string option values
+    and file paths all use URI transformation on input and
+    if the transformation does anything at all dwarfdump reports
+    the input and transformed strings.  This makes it easy
+    to deal with strings and expressions and file paths
+    that are difficult to express in a shell (or that getopt
+    mangles). Options  -q and -U give you  control over this process.
+October 06, 2011
+    The -x abi=mips  frame register abi in dwarfdump.conf is now
+    usable with modern MIPS objects as well as old IRIX objects.
+    There are other mips-* frame register setups described
+    in dwarfdump.conf for anyone testing that nothing new has
+    been added that conflicts with old IRIX/MIPS frame generation.
+October 04, 2011
+    Revised in major ways to do the additional checks and produce the same
+    output as dwarfdump.  But making use of C++ features.
+March 29, 2011
+    All indentations changed to a consistent 4 characters per level.
+    This was a massive but simple change.
+January 26, 2010
+    Changed the default frame-data register names from MIPS to
+    a generic set of registers.  
+    Try  '-x abi=mips' to get the traditional old MIPS register
+    naming.
+June 22, 2009
+    Added the -S option to dwarfdump.
+June 10, 2009
+    Moved the gennames.c code to libdwarf.
+May 4, 2009
+    Replaced awk source-generation of certain functions 
+    with new gennames.c code.
+April 04, 2009
+    Now frame printing (-f and -F) uses a different interface
+    to libdwarf which is far more efficient for the particular
+    purpose of printing all the register rules.  Reduces
+    MxN print time to M (one extreme case reduces from 2 hours
+    to 2 minutes).
+Feb 28, 2009
+    Created this new source base in C++ (from dwarfdump, which
+    is C).

+Dwarfdump2 is a C++ version of dwarfdump. It's intended to
+have improved features and better performance and be easier
+to understand than dwarfdump, but the printed output is intended
+to be the same as dwarfdump (aside from the new features and
+improvements).
+
+If this does not work for you, please let me know.
+
+To build dwarfdump, first build libdwarf in the neighboring
+directory then type
+	./configure
+	make
+
+Installation is a bit primitive.
+      sudo make install
+may or may not work.   
+Some or all of the following might be required on Unix or Linux or MacOS:
+      sudo mkdir -p /usr/local/share/man/man1/
+      sudo mkdir -p /usr/local/lib
+      sudo mkdir -p /usr/local/bin
+Then retry the 'sudo make install' and (if necessary) try
+      sudo chmod a+x /usr/local/bin/dwarfdump
+      sudo chmod a+r /usr/local/share/man/man1/dwarfdump.1
+      sudo chmod a+r /usr/local/lib/dwarfdump.conf
+You don't really need the dwarfdump.1 man page,
+but you might as well have it. If the man page is not visible
+with 'man dwarfdump' try  'man manpath' for hints.
+
+If you don't need others using dwarfdump on your computer,
+just 
+    cp dwarfdump $HOME/bin/dwarfdump 
+(by convention many people put personal executables in $HOME/bin
+and fix up $PATH to refer there) which suffices as 'installation'.
+Also   
+    cp dwarfdump.conf $HOME 
+
+To use dwarf or libdwarf, you may want to install dwarf.h
+and libdwarf.h somewhere convenient.
+You can just copy those two headers to /usr/local/include by hand
+(or anywhere, really, that you have permission to copy to)
+(you may need to use -I/usr/local/include on compile lines
+to reference them there, but see below on configure and make).
+
+Notice that dwarf_names.cc and dwarf_names.h are supplied by
+the release though the Makefile can and may rebuild them.
+Some users find it difficult to get a reliable awk(1) program,
+so for them these prebuilt versions may be useful.
+
+If your headers or libelf/libdwarf are not in the expected places,
+use the make command line to add flags and include directories.
+For example
+  ./configure
+  PREINCS="-I /usr/local/include" POSTINCS="-I /home/x/include"  make
+PREINCS content is inserted before CFLAGS as make(1) is running.
+POSTINCS content is added after the CFLAGS value.
+
+To set LDFLAGS,
+do so at configure time, for example:
+  ./configure LDFLAGS="-L /some/dir"
+And/or use PRELIBS and/or POSTLIBS at 'make' time similar to the use
+of PREINCS and POSTINCS.
+
+If the libdwarf directory
+has both libdwarf.so and libdwarf.a, the libdwarf.so
+will be picked up and
+  "./tag_tree_build: error while loading shared libraries:
+        libdwarf.so: cannot open shared object file:  
+        No such file or directory"
+will probably result.
+Either: remove libdwarf.so  and rebuild or set
+the environment variable LD_LIBRARY_PATH to  the directory 
+containing the .so or use LDFLAGS to set rpath (see just below).   
+It is perhaps simpler to ensure that the libdwarf directory
+only has an archive, not  a shared-library.
+But sometimes one wants a shared library.
+In that case
+one can set ld's -rpath on the gcc command line like this:
+    LDFLAGS="-Wl,-rpath=/some/path/libdir"
+so the shared library can be found at run time automatically.
+
+The same problem may arise with libelf, and the same approach
+will solve the problem.

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]
+  --libexecdir=DIR        program executables [EPREFIX/libexec]

+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]

+                          NO)
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+.TH DWARFDUMP
+.SH NAME
+dwarfdump \- dumps DWARF debug information of an ELF object
+.SH SYNOPSIS
+.B dwarfdump [options] \f2objectfilename\fP
+.SH DESCRIPTION
+The 
+.B dwarfdump
+command prints or checks DWARF sections as requested by specific options.
+With no options (but with the required \f2objectfilename\fP ) 
+all sections print (but some sections cannot be printed independently
+safely, so those are only printed at offsets where the .debug_info section
+refers to those sections).
+.PP
+As of June 2011 the printing options and the checking options
+are mutually exclusive (if checking options are selected 
+the section details are not printed).   When errors are encountered
+dwarfdump does attempt to print sufficient context so that
+one can understand exactly where the error is in the DWARF.
+This change makes checking really large object files
+much easier.
+.PP
+The format is intended to be human readable.
+If a script is to parse the output, the
+.B \-d
+option is useful.
+.PP
+Not all sections actually exist in any given object file.
+.PP
+The format may change from release to release, so it is
+unwise to depend too heavily on the format.
+.PP
+Frame information (.debug_frame and .eh_frame) is heavily
+dependent on the ABI/ISA of the object file.  
+By default we use a generic set of register names
+handling up to 100 registers named r0-100.
+The '-R' option uses a built-in generic register name set
+handling up to 1200 registers named r0-r1199.
+The '-x abi=<abi>'
+description below shows how to name an abi and use that to guide
+the -f or -F processing.
+Unless the cpu for the object file being dumped has many registers,
+do not use -R or -x abi=generic as those can be needlessly 
+slow dumping frame sections. Instead, use the correct
+abi (if it exists in dwarfdump.conf) or a generic such
+as -x abi=generic100 or -x abi=generic500.
+To get MIPS/IRIX register names names and call the old version 2 libdwarf
+frame interface use the option '-x abi=mips'.
+Without '-R' or '-x abi=<abi>' dwarfdump ignores
+the dwarfdump.conf file and uses compiled-in generic set of
+register names.
+If no '-x name=<path>' is given, dwarfdump
+looks for "./dwarfdump.conf", "$HOME/.dwarfdump.conf", "<install-prefix>/lib/dwarfdump.conf" and takes the first it finds.
+If one or more '-x name=<path>' is given the last of these is
+used and all other such files are ignored.
+.PP
+Some -k (checking) options print so-called harmless errors.
+These are compiler errors that do not cause any
+known problem and are only detected inside libdwarf itself.
+These are difficult to properly report in dwarfdump and
+any error strings may not appear close to the time the
+error was encountered.
+.SH URI STYLE INPUT STRINGS
+.PP
+The <objectfilename> and the options taking name strings look for URIs and
+translate the URI strings to characters by default
+(see -x, -c<compiler name>, -S, -u).
+So any single % character is treated as if the following two
+characters are hex digits representing the underlying true character.
+Various characters are meaningful to shells (such as bash or sh) 
+and to getopt (such as the space character) 
+If the URI translation does anything it prints the before and after
+of the URI translation on standard output, so inspection of the first
+lines of output will show if URI did anything.
+The actual options themselves are assumed to be non-URI.
+So in the option '-cS&T' the -c portion must be non-URI, but the
+& character might cause input issues so '-cS%26T' could be used instead.
+To actually input a single % character (in a name, for example), 
+double it to %% on the command line.
+.PP
+Options -U (turning off URI interpretation) and -q (making finding
+URI sequences silent) give finer control of URI interpretation.
+PP
+As an example, to get a string'a b' make the string 'a%20b'
+(here the quote  (') is for exposition not part of the string, though
+quote is certainly problematic in a name).
+Instead of escaping " quotes in the string,  type %25, as in
+   'a "b'  should be typed   'a%20%25b'
+Any characters can be typed in URI style, not just characters
+which are problematic to the shell or getopt.
+We strongly suggest you not type URI-style characters where
+such are not needed or use
+the % character itself in command line strings unless you must.
+.SH PRINTING OPTIONS
+.TP
+.B \-a
+Print each section as independently as possible. Sections that
+can safely be printed independently (like .debug_abbrev)
+have relevant info printed in the report (sometimes dependent
+on -v).
+
+.TP
+.B \-b
+Print the .debug_abbrev section. Because the DWARF specfications
+do not rule out garbage data areas in .debug_abbrev (if they are not
+referenced from .debug_info) any garbage bytes can result in
+this print failing.
+
+.TP
+.B \-c
+Print locations lists.
+
+.TP
+.B \-f
+Print the .debug_frame section.
+.TP
+.B \-F
+Print the .eh_frame section.
+
+.TP
+.B \-i
+Print  the .debug_info section.
+
+.TP
+.B \-l
+Print the .debug_info section and the associated line section data.
+
+.TP
+.B \-m
+Print the .debug_macinfo section.
+
+.TP
+.B \-N
+Print .debug_ranges section.  Because the DWARF specfications
+do not rule out garbage data areas in .debug_ranges (if they are not
+referenced from .debug_info) any garbage bytes can result in
+this print failing.
+

+
+.PP
+Having dwarfdump print relocations may help establish whether

+
+.TP
+.B \-g
+Normally used only for testing libdwarf, this tells dwarfdump to

+function (a function that cannot handle all current
+location lists).
+.TP

+
+.SH CHECKING OPTIONS
+.TP
+.B \-cg 
+Restricts checking to compilers whose
+producer string starts with 'GNU'
+and turns off -cs .
+
+.TP
+.B \-cs
+Restricts checking to compilers whose
+producer string starts with 'SN'
+and turns off -cg .
+.TP
+.B \-cname
+Restricts checking to compilers whose
+producer string contains 'name' (not case sensitive).
+The 'name' is read as a URI string.
+
+.TP
+.B \
+-ka        : Turns on all checking options except -kxe (-kxe might
+             be slow enough one mignt not want to use it routinely.)
+
+.TP
+.B \
+-kb        : Checks for certain abbreviations section errors when reading
+             DIEs.
+.TP
+.B \-kc 
+Checks for errors in constants in debug_info.
+.TP
+.B \-kd 
+Turns on full reporting of error totals per producer.
+(the default shows less detail).
+.TP
+.B \-ke 
+Turns on reading pubnames and checking for fde errors.
+.TP
+.B \-kf 
+Turns on checking for FDE errors.
+.TP
+.B \-kF 
+Turns on checking for line table errors.
+.TP
+.B \-kg 
+Turns on checking for unused gaps in .debug_info (these
+gaps are not an error, just a waste of space).
+
+.TP
+.B \-ki 
+Causes a summary of checking results per compiler (producer)
+to be printed at the end.
+.TP
+.B \-kl 
+Turns on locations list checking.
+.TP
+.B \-km 
+Turns on checking of ranges.
+.TP
+.B \-kM 
+Turns on checking of aranges.
+.TP
+.B \-kr
+Turns on DIE tag-attr combinations checking.
+.TP
+.B \-kR 
+Turns on reading DIEs and checking for forward declarations
+rom DW_AT_specification attributes.
+(which are not an error but can be a source of inefficiency
+for debuggers).
+.TP
+.B \-ks 
+Turns on extra reporting for some DIE errors checking detects .
+.TP
+.B \-kS 
+Turns on checking DIE references for circular references.
+.TP
+.B \-kt 
+Turns on tag-tag combinations checking.
+.TP
+.B \-kx 
+Turns on check_frames.
+.TP
+.B \-kxe 
+Turns off basic check_frames and turns on extended frame checking.
+.TP
+.B \-ky 
+Turns on type_offset, decl_file checking,
+
+.SH OPTION MODIFIERS
+
+.TP
+.B \-C 
+Normally when checking for tag-tag or tag-attribute combinations
+both the standard combinations and some common extensions are allowed.
+With -C the extensions are taken out of the allowed class of combinations.
+
+.TP
+.B \-d
+When printing DIEs, put all the attributes for each DIE on the same (long)
+line as the TAG.  This makes searching for DIE information
+(as with grep) much simpler as the entire DIE is on one line.
+
+.TP
+.B \-D
+Turns off the display of section offsets and attribute values in printed output.
+So the .debug_info output isjust TAGs and Attributes.
+For pubnames (and the like) it removes offsets from the output.
+For locations lists it removes offsets from the output, but that
+is useless since the attribute values don't show so neither does
+the location data.
+
+.TP
+.B \-e
+Turns on truncation of attribute and tag names. For example
+DW_TAG_foo  becomes   foo .    Not compatible with
+checking, only useful for printing DIEs.
+
+.TP
+.B \-G
+When printing, add global offsets to the offsets printed.
+
+.TP
+.B \-H number 
+When printing or checking .debug_info, this terminates
+the search after 'number' compilation units.  When printing
+frame information this terminates the FDE reporting 
+after 'number' FDEs and the CIE reporting (which occurs if one adds -v)
+after 'number' CIEs.  Example   '-H 1'
+
+.TP
+.B \-M 
+When printing, this means one want to have the FORM show for each attribute.
+If a -v is also added (or more than one) then details of any form indirection
+are also shown.
+
+.TP
+.B \-n 
+When printing frames, this turns off the search for function names.
+In a really large object the search can take more time than
+one wants to wait, so this avoids the search.
+
+.TP
+.B \-Q 
+Suppresses section data printing (set automatically with a checking option).
+
+.TP
+.B \-R 
+When printing frames for ABIs with lots of registers, this allows
+up to 1200 registers to be named (like R999) without choosing an ABI
+with, for example '-x abi=ppc'
+
+.TP 
+.B \-v
+Increases the detail shown when printing.
+In some sections, using more -v options
+will increase the detail (one to three are useful) or may
+change the report to show, for example, the actual
+line-data-commands instead of the resultant line-table.
+
+.SH SELECTIVE ENTRY PRINTING
+
+.PP
+These -S options stand alone and basic print information about the compilation
+unit and DIE where the string(s) appear.
+At most one of each of the following is effective (so for example
+one can only have one 'match', but one can 
+have a 'match', an 'any', and a 'regex').
+Any -S causes the .debug_info section to be inspected.
+No checking options or printing options should be supplied with -S.
+
+.TP
+.B \-S match=string
+When printing DIEs
+for each tag value or attribute name that matches 'string' exactly
+print the compilation unit information and its section offset.
+Any CU with no match is not printed.
+The 'string' is read as a URI string.
+.TP
+.B \-S any=string   
+When printing DIEs
+for each tag value or attribute name that contains 'string'
+somewhere in the tag or attribute (case insensitive)
+print the compilation unit information and its section offset.
+Any CU with no match is not printed.
+The 'string' is read as a URI string.
+.TP
+.B \-S regex=string 
+When printing DIEs
+for each tag value or attribute name where the 'string' reqular
+expression matches print the compilation unit information
+and its section offset.
+Any CU with no match is not printed.
+The 'string' is read as a URI string.
+
+.PP
+The string cannot have spaces or other characters which are
+meaningful to getopt(3) and the shell will strip off quotes and
+other characters.
+So the string is assumed to be in URI style and is translated.
+In other words, to match 'a b' make the -S string 'a%20b'
+Instead of escaping " quotes in the string,  type %25, as in
+   'a "b'  should be typed   'a%20%25b'
+(the ' are for exposition here, not part of the strings).
+Any characters can be typed in URI style, not just characters
+which are problematic to the shell or getopt.
+.PP
+The -S any= and -S regex= options are only usable
+if the library functions required are found at configure time.
+.PP
+The -W option is a modifier to the -S option, and
+increases the amount of output -W prints.
+Now we show the -W in context with a -S option.
+
+.TP
+.B \-S match=string1 -W
+Prints the parent tree and the children tree for the
+DIEs that -S matches.
+
+.TP
+.B \-S match=string2 -Wp
+Prints the parent tree for the DIEs that -S matches.
+
+.TP
+.B \-S match=string3 -Wc
+Prints the parent tree for the DIEs that -S matches.
+
+.SH OTHER OPTIONS
+
+.TP
+.B \-# number 
+This option controls internal debugging output,
+higher numbers mean more debug actions. See the source code.
+
+
+.TP
+.B \-x name=/p/a/t/h.conf 
+The file path given is the name of a file assumed to be
+a dwarfdump.conf-like file.
+The file path is read as a URI string.
+
+.TP
+.B \-x abi=ppc  
+Selects the abi (from a dwarfdump.conf file) to be used in
+printing frame information (here using ppc as an example).
+The abi is read as a URI string.
+
+.TP
+.B \-P 
+When  checking this adds the list of compilation-unit names
+seen for each producer-compiler to the printed checking results.
+.TP
+.B \-q
+When a URI is found and translated while reading
+the command line, be quiet about
+the URI translation. That is,  don't print the
+original and translated option strings.
+
+.TP
+.B \-E 
+Turns on printing object-internal header data for some
+systems (for Unix/Linux does nothing).
+
+.TP
+.B \-u cuname 
+Turns on selective printing of DIEs (printing like -i).
+Only the DIEs for a compilation unit that match the
+name provided are printed.
+If the compilation unit is ./a/b/c.c
+the 'cuname' you provide should be c.c as the characters
+through the final path-separating / are ignored.
+If 'cuname' begins with a / then the entire name string
+of a compilation unit must match 'cuname'.
+The 'cuname' is read as a URI string.
+
+.TP
+.B \-U
+Turn off the URI interpretation of the command line
+strings entirely.  Must be be on the command line before
+any URI strings encountered to be fully effective.
+
+.TP
+.B \-z
+No longer suported.
+
+

+
+<install-prefix>/lib/dwarfdump.conf
+.SH NOTES
+In some cases compilers use DW_FORM_data1 (for example)
+and in such cases the signedness of the value must be taken
+from context. Rather than attempt to determine the
+context, dwarfdump prints the value with both signednesses
+whenever there is ambiguity about the correct interpretation.
+For example, 
+"DW_AT_const_value           176(as signed = -80)".
+For normal DWARF consumers that correctly and fully
+evaluate all attributes there is no ambiguity of signedness:
+the ambiguity for dwarfdump is due to dwarfdump evaluating
+DIEs in a simple order and not keeping track of much context.
+.SH BUGS
+Support for DWARF3 is being completed but may not be complete.

+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+David Anderson, September 20, 2010
+
+The dwarfgen application is intended as both a vehicle
+for testing dwarf-generation by libdwarf and as an example
+of how one uses libdwarf to generate DWARF.
+In addition, it should be useful as a test vehicle for
+evaluating future changes to the DWARF standard.
+
+It is necessary as a test-vehicle so that the libdwarf
+producer code can be updated to allow more recent features
+of DWARF to be supported while trying to guarantee current
+producer code users are correctly supported.
+
+By default dwarfgen produces a fake a.out. By that we mean
+that no relocation sections are written.  Instead, relocations
+are processed directly by dwarfgen.
+Perhaps at some point a more a.out-like output will be optionally
+supported.

+//  dwarfgen [-t def|obj|txt] [-o outpath] [-c cunum]  path
+
+//  where -t means what sort of input to read
+//         def means predefined (no input is read, the output
+//         is based on some canned setups built into dwarfgen).
+//         'path' is ignored in this case. This is the default.
+//         
+//         obj means 'path' is required, it is the object file to
+//             read (the dwarf sections are duplicated in the output file)
+//         
+//         txt means 'path' is required, path must contain plain text
+//             (in a form rather like output by dwarfdump)
+//             that defines the dwarf that is to be output.
+//
+//  where  -o means specify the pathname of the output object. If not
+//         supplied testout.o is used as the default output path.
+//  where -c supplies a CU number of the obj input to output
+//         because the dwarf producer wants just one CU.
+//         Default is -1 which won't match anything.

+-------------------------------------------------------------
+April 14, 2000  davea@sgi.com
+Corrected minor bugs in production of 32bit dwarf with
+64 bit pointers.  Fixed omissions in legal
+DIE children of a DIE.  Make small changes in
+description of regster output in frame information
+access.
+
+-------------------------------------------------------------
+Mar 7, 2000 davea@sgi.com
+Corrected line table reading so it will handle
+reading an object with a diffent number of standard
+op codes than at libdwarf compile time.
+This was possible all along, but libdwarf did
+not do it right.
+
+-------------------------------------------------------------
+Dec 8, 1999  davea@sgi.com
+Changed nearly all files.
+Adding the capability to read and produce
+the new, accepted by committee, but not
+released-publically 64bit extension proposal
+dwarf data.
+This allows dwarf compilation units
+with 64bit section offsets and 32bit
+sections offsets to be mixed. 
+So that offsets can grow very large with
+64-bit pointer applications (though 64bit pointers
+and 64bit offsets are not the same notion).
+
+In addition, removed all the contents (or nearly all)
+of the dwarf_funcs.c dwarf_weaks.c dwarf_vars.c,
+and dwarf_types.c, as the data format is identical
+to dwarf globals (pubnames) and there is no need
+to duplicate all that code.
+
+All these sections whose contents were gutted are things that
+are formatted exactly like pubnames, and all are sgi
+extensions.  Now the implementation uses pubnames code
+(dwarf_global.c) to do the work for all the pubnames-like
+sections.
+
+The (minor, IMO) difference is that in case of an incorrect
+dwarf file (leading to libdwarf being unable to process
+something in one of the sgi-specific pubnames-like sections)
+the dwarf error string may reference pubnames when weaks,
+static functions, static variables, or global typenames are
+actually the problem.  This is fixable, however the price would
+appear to be that even globals would need to call a helper
+function (to pass in the correct error return).  Right now the
+dwarf_weaks.c calls the dwarf_global.c function, for example,
+with no extra arguments indicating the true section involved.
+(Other approaches keeping the original error codes exist.
+Producing the code uniquely via macros seems unappealing.
+Inline functions would be ok though.  This version does not
+inline the functions we are talking about, such as
+dwarf_global_name_offsets() when called from
+dwarf_type_name_offsets().)
+
+Since these extra sections are SGI only and only really used by
+SGI's workshop product, and the performance hit is small, the
+extra function calls in reading each seem acceptable.
+
+
+-------------------------------------------------------------
+Sep 29,1999 davea@sgi.com
+Changed many files, so that it is easy to switch
+from 32bit-offset-only (like cygnus
+and dwarf2 v 2.0.0)  to sgi/mips 64 bit dwarf.
+See NEWS for more info on 32bit-offset.
+
+
+-------------------------------------------------------------
+Since Oct 95 and before May, 1996
+
+Added the function dwarf_get_cie_of_fde() which makes it possible
+to remember a single fde/cie set out of a block usefully.
+
+Enhanced doc of dwarf_bitoffset()
+
+Added new function dwarf_global_formref() so all reference
+forms can be retrieved.
+
+Fixed bug in retrieving array bounds: was failing to sign extend
+formsdata.
+
+Added function dwarf_get_fde_info_for_all_regs(), which makes
+retrieval of the complete set of registers (as needed by
+debuggers and exception handlers) effectively N times faster
+than getting them one a time where N is the number of registers.
+
+Added support for exception table handling (really just support
+for a reference to an exception table for c++ exceptions).
+
+Fixed a bug where useless extra space (several megabytes)
+were malloc'ed for the abbreviations table by the libdwarf
+consumer code.

@@ -0,0 +1,61 @@
+This document is a brief description of the main
+coding style conventions in libdwarf.   Many of them
+will be obvious from the code, but over time some
+accidental diffences crept in.
+
+
+Code should be indented in multiples of 4 spaces, and
+tabs should not be used to indent the source code.
+Use the dicheck program to check indenting.
+
+
+dwarf.h and libdwarf.h must have all arguments commented
+out as these are public headers.  Because a  prototype like
+int dwarf_example_prototype(Dwarf_Debug foo);
+would be made unusable by  a legitimate
+preprocessor definition
+such as  #define foo +
+
+The struct naming convention is 'struct  Camel_Caps_s' for the
+struct and   'Camel_Caps' for any typedef for the struct.
+Admittedly having both camel caps
+and an underbar is an unusual convention, but it is
+the way the coding was begun in the early 1990's and
+we should remain consistent now.
+
+All user-referenceable data and functions 
+and user_visible types should begin with DW_ or
+dwarf_.  Non-static libdwarf global data and functions
+should begin with _dwarf (a somewhat questionable
+approach, but workable).
+
+Function names should be all lower case with underbars
+for readability.
+
+There should never be static data in any function.
+Nor should there ever be static data outside of libdwarf
+functions.  libdwarf can be called from multiple threads
+(but only from one thread per Dwarf_Debug) and multiple
+Dwarf_Debug objects can be open at one time.
+Instead place such data per-dbg into the Dwarf_Debug structure
+in dwarf_opaque.h. Similarly for the producer code.
+
+Function-local variables should be lower-case with
+underbars for readability.   It's ok for a small loop
+with counters to use single letter names like i or k or m.
+
+structure members should have a struct-specific
+2-character prefix to the name (followed by
+an underbar). That makes it much
+easier to grep for uses of members.
+
+Try to keep lines under 80 characters in length.
+
+Ensure every if() has {} to enclose the actions.
+
+Use libdwarf.h types for all the data objects you define,
+though sometimes an 'unsigned' or 'int' or 'size_t' is
+ok in restricted circumstances.  Dwarf_Unsigned Dwarf_Signed
+are the preferred integer types for general use.

+        leave the defines visible (the defines are HP extensions).
+      * libdwarf.h: Add new dwarf3 interface to frames.
+        (which actually is also a better interface to dwarf2 info,
+        not strictly for dwarf3).
+      * dwarf_alloc.c: Add 'constructor/destructor' pointers 
+        to the initialization table so we can handle a more

+        by caller and library).
+      * dwarf.h: New commentary on ABI/register-number issues.
+      * libdwarf.h: New commentary on ABI/register-number issues.
+2006-03-26 David Anderson <davea@sgi.com>
+      * dwarf_line.c: file_entry_count local was not initialized.

+        variable.
+      * libdwarf2.1.mm: Document new dwarf_srclines_dealloc()
+        deallocation routine for dwarf_srclines().
+

+2005-04-13 David Anderson <davea@sgi.com>
+      * dwarf_error.c: Error  codes 194 and 195 were missing
+	strings, added them to table.

+      * dwarf_init_finish.c: Add dwarf_get_section_max_offsets()
+          to allow clients to do additional error checking.
+          This code will have to change again, so leaving it
+          undocumented. As written it's not useful for COMDAT
+          style DWARF sections.
+      * libdwarf.h: Added prototype for dwarf_get_section_max_offsets().
+
+2005-03-31 David Anderson <davea@sgi.com>

+        much (but not all) of gcc 3.3 gcc 3.4 .eh_frame
+	'z' augmentation.  Gives error on attempting
+        to get z augmentation data since such is not
+        completely handled.
+
+2005-03-18 David Anderson <davea@sgi.com>
+      * dwarf_frame.h dwarf_frame.c: The gcc .eh_frame
+        info did not print correctly so we now access the
+	correct section data so it prints. Still no support
+	for dwarf3 frame operators.
+      * dwarf_macro.c: Detect end-of-macros properly
+        (stopped too soon before).
+	
+2005-02-14 David Anderson <davea@sgi.com>

+      * dwarf_init_finish.c (_dwarf_setup): Remove calls to
+        dwarf_load_object for .debug_info, .debug_abbrev sections.
+      * dwarf_opaque.h: Add new fields to Dwarf_Debug so
+        we don't need to pre-load .debug_info, .debug_abbrev
+      * dwarf_util.h: Fix READ_AREA_LENGTH macro so it uses
+        only length itself to determine which format the
+        length is.
+
+2003-01-14 David Anderson <davea@sgi.com>
+      * dwarf_loc.c: Made comment at head of dwarf_loclist()
+      a bit clearer.
+
+2002-11-22 Tom Hughes <thh@cyberscience.com>
+      * dwarf_macro.c: Corrected bugs in macro-info functions.
+
+2002-10-29 David Anderson <davea@sgi.com>
+      * dwarf_init_finish.c: The libelf_sgi mods
+      left a HAVE_ELF64_GETSHDR ifdef in the wrong place 
+      so folks without Elf64 could not build. Fixed.
+
+2002-10-21 David Anderson <davea@sgi.com>
+      * dwarf_form.c: the form_ref functions were failing to
+      add in cc_extension_size when checking for offset
+      legality. Thanks to Kelly O'Hair <kelly.ohair@sun.com>
+      for pointing out the 4 places this was wrong.
+      Used cu_context local pointer to avoid numerous
+      double indirections.
+
+2002-08-14 David Anderson <davea@sgi.com>
+      * dwarf_string.c (dwarf_get_str): Return
+      DW_DLV_NO_ENTRY when offset is just at the end of the
+      sections, making it possible to use dwarf_get_str
+      to print the section independently.
+      * libdwarf2.1.mm, libdwarf2.1.ps: Document the
+      revised dwarf_get_str interface (which was not
+      fully thought thru before).
+      * dwarf_line.c (dwarf_srcfiles): Avoid core dump
+      when DW_AT_comp_dir absent (it's not required).
+
+
+2002-07-31 David Anderson <davea@sgi.com>
+      * pro_types.c (_dwarf_transform_simplename_to_disk): correct
+      generation of .debug_info size field.
+      Thanks to Kelly O'Hair <kelly.ohair@sun.com> for pointing out
+      the bug.
+
+2002-05-23 Daniel Gohman <gohmandj@sgi.com>
+      * dwarf_init_finish.c: Add support for using SGI's
+      ELF library as an alternative to using AT&T-style
+      libelf.
+      Add a new function _dwarf_load_section to handle
+      loading of sections.
+      * dwarf_opaque.h: Add entries to Dwarf_Debug_s to
+      store section indicies.
+      * most consumer files: Load sections on demand so
+      that unneeded sections don't get loaded.
+      * dwarf_init_finish.c: Fixed an incorrect check for
+      duplicate .eh_frame sections.
+
+2002-04-25 Kelly O'Hair <kelly.ohair@sun.com>
+      * pro_section.c (_dwarf_pro_generate_debuginfo): add
+      required dwarf2 sec 7.5.3 trailing null byte 
+      to .debug_abbrev per compilation-unit.
+
+2002-03-31 David Anderson <davea@sgi.com>
+      * dwarf_abbref.c (dwarf_get_abbrev): change 
+      DW_DLE_DEBUG_ABBREV_NULL to DW_DLE_DWARF_ABBREV_NULL. 
+      Former was wrong code.
+      * libdwarf2.1.mm: correct argument reference, returned_abbrev
+      not returned_fde in dwarf_get_abbrev discussion.
+      
+2002-03-07 David Anderson <davea@sgi.com>
+      * libdwarf.h: added struct Elf declaration
+      to reduce dependency on header include ordering. 
+
+2002-02-11 David Anderson <davea@sgi.com>
+      * libdwarf2.1.mm libdwarf2.1.ps:
+      dwarf_offdie can return DW_DLV_NO_ENTRY and that
+      is now documented.
+      * dwarf_loc.c: if the length of a location description
+      is zero that is ok, not an error. dwarf2 sec 2.4.1.
+
+2002-01-10 David Anderson <davea@sgi.com>
+      * dwarf_opaque.h, dwarf_init_finish.c: if libdwarf does
+      the elf_begin() it must also do the elf_end() to
+      avoid a memory leak, and now does this correctly.
+
+2002-01-10  David Anderson <davea@sgi.com>
+      * dwarf_init_finish.c:  Using a variable to
+      hold ELF_C_READ_MMAP.  Really motivated by
+      code not added to this source. 
+      * dwarf_die_deliv.c: Added comments, moved
+      a couple variables to local scope from function scope.
+
+      * dwarf.h: Added some #defines which were specified in the Dwarf
+      2.1 Dwarf draft 5 (now called dwarf 3 draft 5).
+
+2001-09-18  David Anderson davea@sgi.com
+	* all files: applied gnu indent with
+	-bad -bap -nbbo -br -ce -brs 
+	-l72  -lc72  -hnl  -nprs  
+	-fca -i4  -lp -psl -npcs 
+	Code should use this set in libdwarf.
+
+
+2001-08-21  "kelly o'hair" <kelly.ohair@eng.sun.com>
+	* pro_section.c:  If one called dwarf_add_file_decl()
+	  or dwarf_add_directory_decl() but never added a line,
+	  .debug_line was not produced.  This was a mistake,
+	  as if any file or directory was provided .debug_line
+	  should be produced. 
+
+2001-08-06  davea@sgi.com
+	* libdwarf2.1.mm: documented dwarf_dealloc rules
+	  more clearly. (.ps updated too)
+	* mips_extensions.mm: documented the way SGI
+	  gets frame stack pointer out of debug_frame.
+	  (.ps updated too)
+
+2001-06-14  davea@sgi.com
+	* dwarf_leb.c: changed around where bytes counted in
+	  _dwarf_decode_s_leb128 so it's easier to tell it is correct.
+	  And removed one loop completely: it was
+	  an early attempt at performance improvement and
+	  is no longer relevant.
+
+	* dwarf_global.c: added new 
+	  dwarf_get_cu_die_offset_given_cu_header_offset function
+	  to get CU die offset (as the long name says).
+	  A variety of functions return cu-header-offsets, so
+	  this is useful at times.
+	  Used locals to reduce the number of indirections
+	  and make things easier to follow.
+
+	* dwarf_arange.c: added new dwarf_get_arange_cu_header_offset
+	  function so dwarfdump could print the cu header offset
+	  (which appears in the arange headers).
+
+	* libdwarf2.1.mm: documented the above new functions.
+
+2001-06-07  davea@sgi.com
+	* dwarf_leb.c: shift operator was not being applied
+	  to full size of Dwarf_Signed/Unsigned for 64bit
+	  Dwarf_Signed/Unsigned (ILP32 compile) so
+	  large numbers not decoded if signed.
+	* pro_encode_nm.c: added {} in a couple if/else
+          for 'clarity' and to make inserting debug printf easier.
+	* pro_expr.c: Added comments explaining why possible
+	  compiler (gcc) warnings are ok, the result is safe. 
+
+2001-05-30  davea@sgi.com
+	* pro_reloc_stream.c: Wrote Set_REL32_info and 
+	  Set_REL64_info macros
+	  from generic ELF abi documents to make use acceptable
+	  when IRIX elfaccess.h is not available.
+
+2001-05-30  "kelly o'hair" <kelly.ohair@eng.sun.com>
+	* Makefile.in: was missing   pro_macinfo.o
+ 	  pro_encode_nm.o dwarf_macro.o from the OBJS list.
+
+2001-05-22  davea@sgi.com
+	* dwarf_frame.c, pro_expr.c: Added comments on why
+	  casts are safe in spite of gcc warnings (4 places total).
+
+2001-05-18  Dan Gritter <dgritter@us.ibm.com>
+	* dwarf_loc.c DW_OP_bregx operands are unsigned
+	  reg num followed by signed offset.
+
+2001-04-11  David Anderson <davea@sgi.com>
+	* dwarf_die_deliv.c: check for 0 abbreviation code
+	  and return a 'no entry' return value when found.
+	  (normal dwarf2, 0 means no DIE, the end of some set of DIEs.)
+
+2001-01-16  David Anderson <davea@sgi.com>
+
+	* pro_die.c: set ar_reloc_len field
+	in all cases.
+
+2000-12-14  David Anderson <davea@sgi.com>
+
+	* dwarf_frame.h: clarified some comments.
+
+2000-12-14  Ulrich Drepper <drepper@cygnus.com>
+
+        * dwarf_line.c: Now sets DW_LNE_end_sequence to
+        default_is_stmt, the correct value, not is_stmt.
+
+
+2000 Aug 24  davea@sgi.com
+  dwarf_error.c: a dwarf_init() failure resulted in this
+	using a static Dwarf_Error struct. And dwarf_dealloc
+	did not deal properly with that. 
+  dwarf_alloc.c dwarf_alloc.h: these had DYNAMIC_CHUNK protected code
+  	which was never used.  Deleted the unused code. Added a small
+  	comment (hopefully useful) to dwarf_alloc.h.
+
+	And now deals correctly with a null dbg  on
+	DW_DLA_ERROR  due to failed
+	dwarf_init() call (or due to other error in calling
+	libdwarf that results in libdwarf not knowing the dbg,
+	a likely far more common case) and frees the memory.
+	This used to result in chaos (depending on your
+	luck...).
+
+2000 Aug 23  davea@sgi.com
+  libdwarf2.1.mm, ps.  Failed to mention that dwarf_finish()
+  has to be accompanied by elf_end() if dwarf_init() was used
+  to initialize libdwarf to truly release all stuff.
+  Added text to dwarf_finish() describing how to do that.
+2000 April 14  davea@sgi.com
+
+  dwarf_abbrev.c - 1.22
+        - When it is a null abbrev entry, return it correctly so it can be
+          printed (meaning fill out all the return-parameters so the caller can
+          do the right thing).
+
+  dwarf_init_finish.c - 1.48
+        - For most sections, simply having an empty section (present but empty)

+          overlooked this small aspect before in one place
+  dwarf_query.c - 1.48

+        - Allowing generation of correct dwarf2 with the 1999 64bit dwarf
+          extension, and reading all forms of dwarf2 compatibly (all 32/64bit
+          dwarf2 section  forms).
+
+This adds the ability to consume and produce both sgi 64bit
+and the new dwarf2 committee-approved 64bit dwarf extension.
+As a result of the new dwarf2 stuff , a producer (compiler)
+can mix 32 and 64bit dwarf (for a 64bit object) and the
+linker will work seamlessly.  (as long as section sizes don't
+get over 2GBytes).
+
+And the producer is easily configured to produce mips/sgi style
+64bit dwarf or the new form of 64bit dwarf.
+
+This also eliminates a fair amount of rather silly duplicated code.

+
+
+1999 Nov 4
+
+pro_section.c - 1.69
+        - A pointer size entity had an offset-size value used at one place.
+davea@sgi.com
+
+1999 Sep 30
+dwarf_arange.c - 1.18
+        - Changed // comment to /* */.  // failed to compile 
+          with C89 compiler...
+davea@sgi.com
+
+
+1999 Sep 29
+Changed all the producer code
+substantially to allow generating assembler code
+for the dwarf2 (rather similar to what gcc does)
+allowing symbolic relocations.
+MIPS output still generates the binary form.
+davea@sgi.com
+
+
+
+1999 Aug 20
+Stan Shebs (shebs@cygnus.com) pointed out that the pro_util.h
+use of R_MIPS* was a problem compiling on Sun.
+Since the producer code is not really used at present except for
+MIPS/sgi, I've added #ifndefs to pro_util.h which provide zero values
+when <elf.h> does not provide the macros.
+When anyone needs the producer code to actually *work* for non-MIPS
+something better will have to be done.
+
+This has no effect on those simply compiling libdwarf for 
+use by dwarfdump.
+davea@sgi.com
+
+1999 July 21
+Changed the READ_UNALAGNED macro to call a function
+depending on endianness of the host and the object being read.
+So all the dwarf_* source changed in a trivial way.
+Added support for printing egcs eh_frame section.
+Added a local memcpy-like function to do the cross-endian
+thing where applicable (called by READ_UNALIGNED macro). 
+Because the .eh_frame section 
+after linking can have some zeroed out bytes at the
+end of the CIE/FDE data the code looking for CIEs and FDEs
+now assumes a zero CIE/FDE length means it has reached
+the end of the CIE/FDE data.
+davea@sgi.com
+
+
+1999 June 14
+  Fred Fish fnf@ninemoons.com contributed
+  autoconf'ing of the libdwarf and dwarfdump source.  
+  
+
+  mips_extensions.*  Documented additional old errors
+  in the Dwarf Version 2 spec.
+
+  The ChangeLog before this is incomplete. 
+
+-------------------------------------------------------------
+Since Oct 95 and before May, 1996 davea@sgi.com David Anderson
+
+Added the function dwarf_get_cie_of_fde() which makes it possible
+to remember a single fde/cie set out of a block usefully.
+
+Enhanced doc of dwarf_bitoffset()
+
+Added new function dwarf_global_formref() so all reference
+forms can be retrieved.
+
+Fixed bug in retrieving array bounds: was failing to sign extend
+formsdata.
+
+Added function dwarf_get_fde_info_for_all_regs(), which makes
+retrieval of the complete set of registers (as needed by
+debuggers and exception handlers) effectively N times faster
+than getting them one a time where N is the number of registers.
+
+Added support for exception table handling (really just support
+for a reference to an exception table for c++ exceptions).
+
+Fixed a bug where useless extra space (several megabytes)
+were malloc'ed for the abbreviations table by the libdwarf
+consumer code.

+     * dwarf_sort_line.c dwarf_print_lines.c darf_frame.c: Forgot 
+       to commit yesterday.
+       Today's commit includes renaming _dwarf_fde_section_offset
+       _dwarf_cie_section_offset, _dwarf_print_lines, _dwarf_ld_sort_lines
+       to dwarf_* name while retaining support for the now obsolete
+       _dwarf_* form.
+2007-12-08 DavidAnderson <davea42@earthlink.net>
+     * config.h.in, configure.in: Latest linux libelf.h requires
+       _GNU_SOURCE to get off64_t defined so dwarfdump compiles.
+       Only define _GNU_SOURCE  if libelf.h defines off64_t.
+       Regenerated configure.
+     * config.guess, config.sub: Updated to 2.61
+     * acconfig.h: Deleted, removing autoconf complaint.
+2007-11-14 David Anderson <davea42@earthlink.net>
+      * dwarf_frame2.c (gnu_aug_encodings): Now allows 'S' augmentation 
+        character in eh_frame.
+2007-10-16 David Anderson <davea42@earthlink.net>
+      * dwarf_alloc.c: Reformat a comment.
+      * dwarf_die_deliv.c (dwarf_siblingof): When there is no trailing
+        null-DIE in the section, ensure we don't test the contents
+        of a byte past section end.
+      * dwarf_frame.c:  Changed spelling of a local variable
+        so it is easier to grep for and to read.
+      * dwarf_macro.c (free_macro_stack): Was free()ing memory that 
+        _dwarf_get_alloc() had supplied, which could lead to core dump.  
+        Fixed potential memory leaks (said leaks only possible with an
+        error in the macro data, not  with valid macro section
+        data).
+2007-10-15 David Anderson <davea42@earthlink.net>
+      * dwarf_alloc.c: The code supporting the special build
+        flag DWARF_SIMPLE_MALLOC
+        was broken and could coredump libdwarf
+        (which did not affect normal use of libdwarf).
+      * dwarf_opaque.h: Remove the field de_simple_malloc_current
+        as it is no longer used.
+
+2007-09-04 David Anderson <davea42@earthlink.net>
+      * pro_forms.c: Add commentary relating to the

+2007-07-26 David Anderson <davea42@earthlink.net>
+      * pro_frame.c: Added commentary about some missing DWARF3 support.
+      * dwarf_srclines_dealloc.c: File unused, now deleted.
+2007-07-04 David Anderson <davea42@earthlink.net>
+      * libdwarf.h: dwarf_get_loclist_entry() is implemented,
+        removed the erroneous 'unimplemented' comment.
+      * libdwarf2.1.mm: Improved the dwarf_get_loclist_entry()
+        documentation.
+      * libdwarf2.1.pdf: regenerated
+      * dwarf_loclist_entry.c: Removed from distribution, the
+        source has nothing of interest.
+
+2007-07-03 David Anderson <davea42@earthlink.net>
+      * libdwarf.h: Add declaration of dwarf_loclist_from_expr();
+      * dwarf_loc.c: Implement dwarf_loclist_from_expr() and add 
+        sign-extension macro calls to case DW_OP_const4s numbers.
+        Removed unused local variables.
+      * dwarf_form.c: Removed unused local variables.
+      * libdwarf2.1.mm: Document dwarf_loclist_from_expr().
+      * libdwarf2.1.pdf: Regenerated.
+2007-07-01 David Anderson <davea42@earthlink.net>
+      * dwarf_frame2.c: Add commentary.
+      * dwarf_frame.c: Add in block_len for DW_CFA_val_expression
+        so libdwarf does not get confused by this frame expression
+        operator.  Thanks to Cristian Vlasceanu for providing
+        a test case.
+2007-06-29 David Anderson <davea42@earthlink.net>
+      * README: added a note that a few warnings about conversions
+        from pointer to integer are normal at libdwarf compile time.
+2007-05-25 David Anderson <davea42@earthlink.net>
+      * dwarf_frame2.c (_dwarf_get_fde_list_internal): 
+        Correct cie-list-creation so it adds to the tail of the list.  
+        gcc 4.1.2 generates cie-use in an order the code did
+        not properly handle.
+2007-05-08 David Anderson <davea42@earthlink.net>
+      * Makefile.in:  Now generates pdf files.
+      * mips_extensions.mm: The only changes were to eliminate
+        unsupported macro (.PM) and to try to get correct output
+        from groff.  No technical content change intended.
+        The pdf/postscript output remains a little odd though.
+      * libdwarf2.1.mm: Remove troff comment line.
+2007-04-18 Chris Quenelle <chris.quenelle@sun.com>
+      * dwarf_addr_finder.c: repaired comment
+      * dwarf_form.c: add support for DW_AT_SUN_func_offsets
+      * pro_alloc.c: add memory block tracking to find and fix
+	lingering allocations.  This is more important for very large
+	and intensive compiles.
+      * pro_die.c: Implement "markers" which are a generic way to
+	do things like relocations.  You can set a marker on any
+	die, and when dwarf is produced in binary form, you get back
+	a list of your markers with the offset of each one in the binary
+	output.  This is used by the Sun compilers to implement die
+	references that span compile unit blocks.  (I may remove this,
+	it might be unused code related to partial_units and comdat
+	support)
+      * pro_die.c: Also check for loops in the die relationships so
+	that if you add a child twice, or other errors, you won't get
+	an infinite loop or a crash.  Also start passing a DBG structure
+	to all allocation calls to help with memory block tracking.
+      * pro_expr.c: Add a public function to "reset" an expr.  This
+	allows the same expr object to be reused over and over to save
+	memory if you're creating many many expressions for a location list.
+      * pro_finish.c: Free any left over blocks when the user calls
+	dwarf_producer_finish.
+      * pro_forms.c: More support for compressed integer blocks. Modify
+	error diagnostics so that user-defined attributes can be any type.
+	Add support for dwarf_add_AT_ref_address which is just like
+	dwarf_add_AT_address, only it produces a DW_FORM_ref_addr instead
+	of DW_FORM_addr.  This is needed for cross-CU die pointers.
+      * pro_incl.h: add macros to control the spelling of relocation types.
+      * pro_init.c: use new macros to control reloc types
+      * pro_line.h: correct minimum instruction length on x86
+      * pro_opaque.h: add support for markers (see above) and also ability
+	have libdwarf tell the caller where the string constants are so
+	that they can be recorded as strings in case the binary output of libdwarf
+	needs to be converted back into assembly.  That's what
+	Dwarf_P_Per_Sect_String_Attrs is about.
+        Remove de_mem_list as it is never used.
+      * pro_reloc_stream.c: repair prototype and comment for
+	_dwarf_pro_reloc_name_stream64, and use relocation type macros.
+      * pro_section.c: support for markers (see above) and for tracking
+	inline string attributes.  Add code to sort the attributes so that
+	abbreviation table entries will be reduced.  Change treatment of
+	DW_FORM_ref_addr to be more correct.  Some support for packing
+	in the middle of sections, this will probably be removed.
+	Also pass DBg structure to more allocations.
+      * pro_util.h: relocation type values can't be zero.
+2007-04-10 David Anderson <davea42@earthlink.net
+      * dwarf_print_lines.c pro_section.c dwarf_query.c
+        dwarf_alloc.c dwarf_arange.c dwarf_sort_line.c
+        dwarf_global.c dwarf_line.c dwarf_abbrev.c
+        dwarf_frame2.c dwarf_util.c dwarf_loc.c dwarf_util.h 
+        dwarf_die_deliv.c dwarf_frame.c dwarf_macro.c: Additions
+        to source for year 2007 now fit in with pre-existing 
+        copyright wording.  Effectively no change.
+      * dwarf_srclines_dealloc.c: Now has the (always-intended) SGI
+        LGPL copyright wording.
+2007-04-09 David Anderson <davea42@earthlink.net
+      * dwarf_error.h: Add DW_DLE_LINK_LOOP error code (Sun).
+      * libdwarf.h: Add DW_DLE_LINK_LOOP error code (Sun).
+      * dwarf.h: Incorporate Sun extensions. Thanks to
+        Chris Quenelle at Sun Microsystems.
+2007-04-06 David Anderson <davea42@earthlink.net
+      * dwarf_sort_line.c (_dwarf_update_line_sec): initialize
+        Dwarf_Debug_s struct. Thanks to Chris Quenelle of Sun Microsystems.
+        Also initialize other local variables.
+2007-04-02 David Anderson <davea42@earthlink.net
+      * dwarf_form.c (dwarf_formsdata, dwarf_formudata): Use
+        Dwarf_sfixed in dwarf_formsdata, document need for casts,
+        Use Dwarf_Signed as type for READ_UNALIGNED macro use.
+        The only real correction here is for a 64bit long compiled 
+        libdwarf reading 32bit dwarf_formsdata FORM_data4.
+      * dwarf_base_types.h: Now Dwarf_sfixed64 and Dwarf_ufixed64
+        are properly declared (so they are usable).
+2007-03-11 David Anderson <davea42@earthlink.net
+      * Makefile.in: use groff to produce postscript.
+      * libdwarf2.1.mm libdwarf2.1.ps  libdwarf2p.1.mm
+        libdwarf2p.1.ps: Clean up the introduction and history.
+        Add a non-restrictive copyright notice.
+2007-02-23 David Anderson <davea42@earthlink.net
+      * dwarf_util.h: now the macros use do{} while(0)
+      * pro_forms.c dwarf_print_lines.c pro_section.c dwarf_query.c 
+        dwarf_arange.c dwarf_sort_line.c dwarf_global.c dwarf_line.c
+        dwarf_abbrev.c dwarf_frame2.c dwarf_util.c dwarf_loc.c
+        dwarf_die_deliv.c dwarf_frame.c: Now have ;
+        after all dwarf_util.h macros. Also added local variable
+        initializations (compiler noticed).
+      * dwarf_macro.c: was missing include of <stdlib.h> for free() 
+        declaration. 
+      * dwarf_print_lines.c pro_section.c dwarf_query.c dwarf_alloc.c
+        dwarf_arange.c dwarf_sort_line.c dwarf_global.c dwarf_line.c
+        dwarf_abbrev.c dwarf_srclines_dealloc.c dwarf_frame2.c
+        dwarf_util.c dwarf_loc.c dwarf_die_deliv.c dwarf_frame.c
+        dwarf_macro.c: indent run with standard libdwarf options.
+
+2007-02-20 David Anderson <davea42@earthlink.net
+      * dwarf_macro.c  (dwarf_get_macro_details): Now call
+        dwarf_free_macro_stack() at every return so no data
+        is leaked and there is no longer any global data
+        (restoring thread safety).
+2007-02-09 David Anderson <davea42@earthlink.net
+      * dwarf_line.c (dwarf_srclines): Added in calls
+        to dwarf_free_line_table_prefix() which were omitted
+        by accident.  Thanks to  Cristian Vlasceanu for noticing.

+      * All .c files: Mechanically removed tab characters with
+        the expand tool.
+2008-09-29  DavidAnderson <davea42@earthlink.net>
+      * libdwarf.h: DW_DLE_LINE_SET_ADDR_ERROR no longer used.
+        The tests which generated it were bogus.
+      * dwarf_print_lines.c: Print a warning if there are any

+2008-08-14  DavidAnderson <davea42@earthlink.net>
+      * libdwarf2p.1.mm: Make it clearer that dwarf_get_pubnames, dwarf_get_varnames,

+        not just for a single compilation unit. Document version 1.68.
+      * libdwarf2p.1.pdf: Regenerated.
+2008-08-08  DavidAnderson <davea42@earthlink.net>

+        Document version 1.67.
+      * libdwarf2p.1.pdf: Regenerated.
+2008-08-05  DavidAnderson <davea42@earthlink.net>
+      * libdwarf.h, dwarf_error.c:  DW_DLA_PUBTYPE_CONTEXT was a mistake,
+        DW_DLE_PUBTYPE_CONTEXT was intended and is now the spelling (neither 
+        is used).
+      * dwarf_pubtypes.c dwarf_vars.c dwarf_funcs.c dwarf_global.c dwarf_weaks.c:
+        tabs removed and previous strange formatting generated by a tool
+        removed (4 space indent per level now present).
+
+2008-08-05  DavidAnderson <davea42@earthlink.net>
+      * libdwarf2.1.mm: There were numerous places the apostrophe
+        was used incorrectly, thru is now spelled through,
+        and a few other small typographical errors were corrected.
+        The document revision id printed is now 1.67.  
+        There is no technical change in content.
+      * libdwarf2.1.pdf: Regenerated.
+2008-06-17  DavidAnderson <davea42@earthlink.net>
+      * libdwarf.h: Add DW_DLE_STRP_OFFSET_BAD error code.
+      * dwarf_form.c: Add runtime check for strp offset.
+      * dwarf_error.c: Add  DW_DLE_STRP_OFFSET_BAD error code string.
+      * dwarf_init_finish.c, dwarf_opaque.h, dwarf_elf_access.h: Remove 
+        CR characters that crept in.
+2008-06-13  DavidAnderson <davea42@earthlink.net>
+      * libdwarf.h: Remove __SGI_FAST_LIBELF
+        dwarf_original_elf_init.c: Remove __SGI_FAST_LIBELF
+        and fix some indentation botches.
+      * dwarf_init_finish.c: Fix typo in variable name introduced
+        a few days ago.
+      * dwarf_elf_access.c:  Remove __SGI_FAST_LIBELF
+        and fix some indentation botches.

+2008-05-20  DavidAnderson <davea42@earthlink.net>
+      * dwarf_init_finish.c: Expand tabs to spaces.
+2008-05-20  DavidAnderson <davea42@earthlink.net>
+      * dwarf_init_finish.c(dwarf_object_init): When there is no 
+        DWARF information return DW_DLV_NO_ENTRY gracefully.
+        Thanks to Carlos Alberto Enciso for pointing out
+        the bug.
+2008-04-12  DavidAnderson <davea42@earthlink.net>
+      * pro_section.c: Initialize local variables to zero.
+        Change leading tabs to spaces.
+      * pro_reloc_stream.c: Initialize local variables to zero.
+        Change leading tabs to spaces.
+      * pro_reloc.c: Initialize local variables to zero.
+        Change leading tabs to spaces.
+2008-04-04  DavidAnderson <davea42@earthlink.net>
+      * dwarf_base_types.h: Removed unused macro definition.
+      * dwarf_util.c: Altered abbreviations hash table for a small
+        performance improvement and space saving.
+      * dwarf_util.h: Changed declaration for space saving in dwarf
+        abbreviations table.
+2008-04-04  DavidAnderson <davea42@earthlink.net>
+      * libdwarf.h: A trivial change to make a declaration look better.
+      * dwarf_abbrev.h: We record tags in more than 16 bits now just in case
+        we encounter such a thing (increased ab_tag field size), though
+        we should not find such.
+      * dwarf_abbrev.c: Adding a comment about the dwarf TAG value.
+      * dwarf_util.c: Initialize local variables at declaration for safety.
+        Removed truncation of some values: internally record more bits.
+        Rewrote handling of the abbrev table as the old one did not scale
+        to large numbers of abbreviations (things got very slow).
+      * dwarf_util.h: Now has a larger field size in the argument to
+        _dwarf_get_abbrev_for_code (not quite necessary but not harmful).
+      * dwarf_die_deliv.c: Initializing local variables at declaration and
+        removing truncation of bits from some uleb values.
+      * dwarf_die_deliv.h: Increased size of ab_code field.
+      * dwarf_opaque.h: Added a comment about abbreviations.
+      * dwarf_base_types.h: Revised to match addition of new
+        allocation table entry.
+      * dwarf_alloc.h: Document macro definitions and increase one to
+        match new table size.
+      * dwarf_alloc.c: Arrange handling of new DW_DLA_HASH_TABLE_ENTRY
+        (most of the work done in dwarf_util.c).
+2008-02-27  DavidAnderson <davea42@earthlink.net>
+      * libdwarf.h: Fixed minor typo in latest libdwarf.h that gcc did not 
+        complain about. Noted by Josh Fuhs.
+2008-02-26  DavidAnderson <davea42@earthlink.net>
+      * dwarf_alloc.h: Add comment giving placement of DWARF_SIMPLE_MALLOC.
+      * pro_opaque.h: Remove de_access field, it is never used.
+      * libdwarf.h: Add new data structures to allow reading of
+        non-Elf object files.
+      * dwarf_original_elf_init.c: dwarf_init(), dwarf_elf_init()
+        moved here from dwarf_init_finish.c.
+      * Makefile.in: Build new source files dwarf_original_elf_init.c
+        and dwarf_elf_access.c.
+      * dwarf_init_finish.c: All dependencies on libelf and elf
+        have been removed.
+      * dwarf_opaque.h: The elf related info is removed and Dwarf_Debug_s
+        now contains a new structure (from libdwarf.h) to hide object
+        information.
+      * dwarf_elf_access.c: All the Elf-using code is now in this
+        source file and elf details are kept in a struct defined and
+        used here.   Non-libelf and non-elf object access code would
+        write a new source file with their own details using this
+        as an example.
+      * dwarf_elf_access.h: Prototypes for calling between
+        dwarf_original_elf_init.c and dwarf_elf_access.c.
+2008-02-18  DavidAnderson <davea42@earthlink.net>
+      * libdwarf.h: Declare new object-access functions and structures.
+      * dwarf_original_elf_init.c: Traditional dwarf_init() and dwarf_elf_init()
+        are moved to this new source file.
+      * Makefile.in: Add new source files.
+      * dwarf_init_finish.c: Now uses the function pointers, not
+        libelf specific fields or ifdefs.
+      * pro_opaque.h:  Remove de_access field, it is unused.
+      * dwarf_opaque.h: New fields for new object-access functions.
+      * dwarf_elf_access.c: New implementation details for elf access functions
+        moved here from dwarf_init_finish.c.
+      * dwarf_elf_access.h: New function interface so  dwarf_elf_access.c
+        and dwarf_original_elf_init.c can communicate.
+2008-02-08  DavidAnderson <davea42@earthlink.net>
+     * dwarf_print_lines.c: Added commentary to clarify that
+       dwarf_print_lines() and _dwarf_print_lines are intentionally
+       identical.  Initialized local variables so they are alll
+       visibly set to some sensible value.
+2008-02-07  DavidAnderson <davea42@earthlink.net>
+     * dwarf_frame.c (_dwarf_fde_section_offset): A typo
+       in the last release made this an infinite loop.
+       A one character change fixed it. Thanks to Carlos Alberto
+       Enciso for noticing the bug.
+2008-02-04  DavidAnderson <davea42@earthlink.net>
+     * dwarf_incl.h, pro_incl.h: Moved #include of dwarf.h before libdwarf.h
+     * pro_forms.c: Some newer attributes are now handled.
+     * dwarf_print_lines.c: Removed unused #include.
+     * dwarf_sort_line.c: Removed alloca use in favor of
+       malloc and removed the alloca #include.
+     * dwarf_line.c: Removed unused #include.
+     * dwarf_line2.c: Removed unused #include.
+
+2008-02-04  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h: Fix commentary mistakes.
+2008-02-02  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h: Add DW_DLC_OFFSET_SIZE_64 for run-time
+       selection of DWARF3 64bit extension producer offset generation.
+     * libdwarf2p.1.mm: Document DW_DLC_OFFSET_SIZE_64.
+     * pro_init.c (dwarf_producer_init): Now standard DWARF3 is the default.
+     * configure.in: Add --enable-dwarf-format-sgi-irix for those
+       wanting IRIX offset-style DWARF2. Add --enable-dwarf-format-strict-32bit
+       for those wanting strictly 32bit offsets.
+       Otherwise default to generating 64bit offsets from the producer code,
+       but allow the DWARF3 extended 64bit offsets if the flag
+        DW_DLC_OFFSET_SIZE_64 is turned on in the call to dwarf_producer_init().
+     * config.h.in: Provide undefs for the offset macros.
+
+2008-01-25  DavidAnderson <davea42@earthlink.net>
+     * pro_die.c: Changed leading tabs to spaces.
+2008-01-23  DavidAnderson <davea42@earthlink.net>
+     * pro_die.c: Using di_last_child field dwarf_die_link
+       goes from O(N) to O(1) in adding a child.
+       Thanks to Daniel Gollub for the suggestion.
+       An omission in linking left/right children is fixed.
+       Changed some leading TABs to spaces.
+     * pro_opaque.h: Add di_last_child field.
+2008-01-14  DavidAnderson <davea42@earthlink.net>
+     * libdwarf2p.1.mm: Added missing backslash to correct formatting
+       error. Thanks to Daniel Golub for pointing out the ommission.
+     * libdwarf2.p1.pdf: Regenerated.

+     * configure: Regenerated with autoconf 2.64.
+     * config.guess, config.sub: Delete these.
+     * configure.in, README: The --enable-nonshared 
+       option was coded incorrectly. The configure
+       options are --enable-shared and --disable-nonshared
+       work correctly.  Options --disable-shared and --enable-nonshared work
+       correctly as well (these are the default values).
+2009-12-29  DavidAnderson <davea42@earthlink.net>
+     * gennames.c: Add cast to int  in printf so that the printf with *
+       as the field width sees an int, not size_t.
+     * Makefile.in:  Add depenencies for libdwarf.so to match
+       libdwarf.a
+2009-12-26  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h, pro_section.c, pro_reloc_symbolic.c: Reformatted
+       a few lines that were badly formatted. 
+       Initialized local variables where a few were not initialized
+       (this did not affect correctness, just readability).
+2009-11-27  DavidAnderson <davea42@earthlink.net>
+     * dwarf_form.c: Was an incorrect implemenation of
+       the reading of DW_FORM_sec_offset.
+     * libdwarf2.1.mm: Improved the documentation on reading DW_FORM_sec_offset.
+       See dwarf_global_formref() documentation.
+     * libdwarf2.1.pdf: Regenerate.
+2009-11-27  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h, dwarf_form.c, dwarf_query.c: Adding 
+       new form-class for the old DW_AT_MIPS_fde
+       SGI/IRIX extension (offset into .debug_frame).
+2009-11-27  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h: Added dwarf_formexprloc() and a new
+       error code for it.
+     * dwarf_query.c: The new dwarf_get_form_class()
+       function had a typo for the address class.
+     * dwarf_form.c: dwarf_formexprloc() added so one can read
+       DW_FORM_exprloc location expressions.
+     * dwarf_error.c: New error added for dwarf_formexprloc().
+     * libdwarf2.1.mm: Document dwarf_formexprloc().
+     * libdwarf2.1.pdf: Regenerate.
+2009-11-27  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h: Defines typedef Dwarf_Sig8 and
+       the new function dwarf_formsig8().
+     * dwarf_error.c: Now deals with the latest
+       error codes, including a new one for dwarf_formsig8().

+     * libdwarf2.1.pdf: Regenerate.
+2009-11-24  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h: Added enum dwarf_form_class_e and
+       dwarf_get_form_class() so clients have a simple
+       way to get the  form-class mentioned in the DWARF
+       specification. 
+     * dwarf_query.c:  Implemented dwarf_get_form_class().
+     * dwarf_die_deliv.c:  Added dwarf_next_cu_header_b()
+       function as more useful than dwarf_next_cu_header().
+     * dwarf_opaque.h:  Added commentary about CU record.
+     * dwarf_elf_access.c:  Added commentary about the CU header
+       data.
+     * libdwarf2.1.mm: Document dwarf_next_cu_header_b()
+       and suggest users convert to it.
+       Document dwarf_get_form_class().  Rev 1.84
+     * libdwarf2.1.pdf: Regenerate.
+2009-11-23  DavidAnderson <davea42@earthlink.net>
+     * dwarf_line.c:  file_name_is_full_path() did not
+       allow for lower case  in Windows root path
+       detection (with --enable-windowspath at configure
+       time).  Now it does.
+2009-11-17  DavidAnderson <davea42@earthlink.net>
+     * gennames.c: Check the return value from fgets().
+     * dwarf_form.c, dwarf_util.c: Handle DW_FORM_sec_offset, new in DWARF4.
+     * libdwarf2.1.mm: Add comment to macro example to clarify its
+       limitation (it cannot always work).
+     * libdwarf2.1.pdf: Regenerate.
+2009-09-30  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h: Added  dwarf_insert_fde_inst_bytes()
+       to simplify copying an fde.  Added dwarf_get_cie_index()
+       to provide a direct specific way to get a cie index for an fde.
+     * libdwarf2.1.mm: Minor reformatting to make things easier to read.
+       This is revision 1.82.  Documented the new function
+       dwarf_get_cie_index().
+     * libdwarf2.1.pdf: Regenerated.
+     * dwarf.h: Corrected typo, DW_CFA_cfa_offset_extended_sf is 
+       really spelled DW_CFA_offset_extended_sf.
+       Added final new attributes, tag, language.
+     * pro_alloc.c: Reformatting a comment so the line is not so long.
+     * libdwarf2p.1.mm: Clarified that some arguments in fde
+       creation are MIPS/IRIX only (other targets should just pass 0).
+       This is revision 1.27. Document the new function
+       dwarf_insert_fde_inst_bytes().
+     * libdwarf2p.1.pdf: Regenerated.
+     * config.h.in: Added HAVE_WINDOWS_PATH. 
+     * configure.in: Added --enable-windowspath to set
+       HAVE_WINDOWS_PATH.
+     * configure: Regenerated.
+     * pro_section.c: Now allows use of a block of fde instructions
+       from dwarf_insert_fde_inst_bytes(). Some indentation fixed too.
+     * dwarf_line.c: Added detection of Windows full path if
+       HAVE_WINDOWS_PATH defined at library build time.
+     * pro_frame.c: Now handles dwarf3 CFA operations (but not the
+       expression operands yet).  Removed some duplicated code in
+       a switch statement. Fixed commentary typos.
+       Created new function dwarf_insert_fde_inst_bytes().
+     * pro_frame.h: Added fields to support dwarf_insert_fde_inst_bytes().
+     * dwarf_arange.c: dwarf_get_arange_cu_header_offset() was
+       failing to load .debug_info, so a legitimate use of the function
+       might crash a client.
+     * dwarf_frame2.c: If there are CIE records but no FDEs this
+       is not considered a 'NO ENTRY' case.  It is strange
+       but not a formal error and we might want to access the orphan
+       CIE records (to print them when debugging a compiler, for example).
+     * README: Documented --enable-windowspath.
+     * dwarf_frame.c: Adding dwarf_get_cie_index() convenience function.
+2009-09-09  DavidAnderson <davea42@earthlink.net>
+     * libdwarf2p.1.mm: Improved the discussion of
+       dwarf_transform_to_disk_form.
+     * libdwarf2p.1.pdf: Regenerated.
+2009-08-12  DavidAnderson <davea42@earthlink.net>
+     * pro_section.c: The Dwarf_Die argument to fde creation
+       functions is really optional (NULL is ok) and only used
+       for an IRIX/MIPS extension.  So the code now allows
+       a NULL Dwarf_Die argument for these functions.
+     * libdwarf2p.1.mm: Rev 1.24, 11 Aug 2009 now documents
+       the argument as NULL for most users.
+     * libdwarf2p.1.pdf: Regenerated Rev 1.24, 11 Aug 2009.
+2009-08-07  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h: Added to Dwarf_Regtable_Entry_s
+       and Dwarf_Regtable_Entry_s comments.
+     * libdwarf2.1.mm: Revised dwarf_set_frame_rule_table_size()
+       description, making it a bit more complete.
+     * libdwarf2.1.pdf: Regenerated, rev 1.81, 07 August 2009.
+2009-08-05  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h: Interface to dwarf_expand_frame_instructions()
+       changed, the original could not really work right.
+     * libdwarf2.1.mm: Documented revised dwarf_expand_frame_instructions().
+     * libdwarf2.1.pdf: Regenerated, rev 1.80, 05 August 2009.
+     * dwarf_frame.c: Fixed dwarf_expand_frame_instructions();
+2009-08-05  DavidAnderson <davea42@earthlink.net>
+     * gennames.c: Change include from getopt.h to unistd.h
+       so the code is more universally compilable.
+2009-07-24  DavidAnderson <davea42@earthlink.net>
+     * dwarf_frame.c: Change debug printf to use libdwarf.h DW_PR macros
+       instead of %d.
+2009-07-20  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h: Added DW_DLE_NO_ELF64_SUPPORT.
+     * dwarf_elf_access.c: If one has no Elf64 libelf support at build time
+       and runtime one finds an Elf64 object then we return
+       an error (DW_DLE_NO_ELF64_SUPPORT).  Pretending we could handle
+       the elf64 was a bug.
+     * dwarf_error.c: Adding strings for new error codes.
+     * dwarf_elf_access.c: Add error code argument.
+     * dwarf_elf_access.h: Add error code argument.
+     * dwarf_original_elf_init.c: Report the correct error code instead
+       of a generic code.
+
+2009-07-16  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h: Add an error message define relating to rela relocations.
+     * dwarf_alloc.c: Add code to free malloc space (related 
+       to rela relocations).
+     * config.h.in: Add ifdef for Sun host machines so rela processing
+       does not segv.
+     * dwarf_opaque.h: Add a flag to the section data to note that we malloced
+       space when rela relocations are involved.
+     * dwarf_elf_access.c: Refine is_32bit_abs_reloc() and  
+       is_64bit_abs_reloc() for easier debugging.  
+       Add malloc call when doing rela processing
+       as some host libelf libraries make some libelf data areas read-only 
+       (Solaris and Irix for example). The malloc space avoids getting 
+       a segv. 
+2009-07-13  DavidAnderson <davea42@earthlink.net>
+     * dwarf_elf_access.c: some cases had = where == was
+       needed in the reloc switch code.
+2009-07-05  DavidAnderson <davea42@earthlink.net>
+     * dwarf_opaque.h: New data for .rela and unify section data 
+       information.  The changes will require consumers supporting
+       non-elf-objects to make small (hopefully simple) changes.
+     * dwarf_init_finish.c: Note existence of .rela sections.
+     * pro_forms.c: Explicitly allow DW_AT_const_value,
+       DW_AT_entry_pc, DW_AT_call_file, DW_AT_call_line.
+     * dwarf_ranges.c:  Use simplified _dwarf_load_section() interface.
+       Change an accidental C++ style // comment to oldstyle C comment.
+     * dwarf_print_lines.c, dwarf_form.c, dwarf_query.c,
+       dwarf_vars.c, dwarf_pubtypes.c, dwarf_frame3.c, dwarf_funcs.c,
+       dwarf_arange.c, dwarf_global.c, dwarf_init_finish.c,
+       dwarf_line.c, dwarf_opaque.h, dwarf_string.c, dwarf_weaks.c
+       dwarf_util.c, dwarf_loc.c, dwarf_frame.c, dwarf_macro.c, 
+       dwarf_types.c: Use simplified _dwarf_load_section() interface.
+
+2009-07-05  DavidAnderson <davea42@earthlink.net>
+     * dwarf_init_finish.c: Unified some common code into
+       a new local function , reducing file by 60 lines.
+     * dwarf_init_finish.c: Has long checked the wrong field
+       for duplicate debug_info and debug_abbrev. Fixed.
+       Also noted SGI IRIX only sections by adding comments.
+2009-07-04  DavidAnderson <davea42@earthlink.net>
+     * libdwarf.h: Adding new function dwarf_CU_dieoffset_given_die(),
+        and comments on dwarf_get_cu_die_offset_given_cu_header_offset();
+     * libdwarf2.1.mm: documenting dwarf_CU_dieoffset_given_die().
+     * libdwarf2.1.pdf: Regenerated.
+     * dwarf_opaque.h: New structure Dwarf_Section_s consolidates
+       section information into one struct per section with
+       index and size so we remove many Dwarf_Debug_s fields. 
+     * dwarf_print_lines.c, dwarf_form.c, dwarf_query.c, dwarf_vars.c,
+       dwarf_pubtypes.c, dwarf_frame3.c, dwarf_funcs.c,
+       dwarf_alloc.c, dwarf_arange.c, dwarf_init_finish.c ,
+       dwarf_ranges.c, dwarf_line.c, dwarf_abbrev.c, dwarf_string.c,
+       dwarf_weaks.c, dwarf_frame2.c, dwarf_util.c, dwarf_loc.c,
+       dwarf_die_deliv.c, dwarf_frame.c, dwarf_macro.c, dwarf_types.c,
+       Reflect Dwarf_Section_s addition using its fields.
+       Simplify years list of SGI copyright using y-y replacing comma list.
+       Minor reformatting for consistency with 4-space indentation.
+       Initialize uninitialized local variables at declaration.
+     * dwarf_addr_finder.c, dwarf_print_lines.c: Initialize 'res'
+       local variables at declaration to DW_DLV_ERROR.
+     * dwarf_global.c: Add dwarf_CU_dieoffset_given_die().
+       Reflect Dwarf_Section_s addition using its fields.
+       Simplify years list of SGI copyright using y-y replacing comma list.
+       Minor reformatting for consistency with 4-space indentation.
+       Initialize uninitialized local variables at declaration.
+2009-06-06  DavidAnderson <davea42@earthlink.net>
+      * configure.in: The new option --enable_namestable
+        switches build time to generate a runtime binary search
+        in the dwarf_get_TAG_name() etc functions instead of the
+        default switch statement (for the rare case one knows a
+        compiler generates poor switch code).
+      * configure: regenerated.
+      * libdwarf.h: Correct format mistakes and omissions in
+        the Dwarf_Regtable_Entry3_s comments.
+        Add prototypes for dwarf_get_TAG_name() and the related
+        new functions.
+      * dwarf_frame.c: Add {} to clarify some 'if' ranges.
+        Remove code updating the DW_FRAME_CFA_COL row when finishing
+        up establishing the current frame table.  The code should never
+        have been there. Fixed some indentation of function
+        formal parameters.  Removed use of DW_FRAME_CFA_COL 
+        and use de_frame_cfa_col_number instead.
+        In dwarf_get_fde_info_for_reg (the older interface)
+        correctly return the cfa table column in the 'old style'.
+      * gennames.c: Copied from dwarfdump.c (with changes).
+        This generates dwarf_names.c so that libdwarf has
+        functions like dwarf_get_TAG_name() which returns
+        functions like dwarf_get_TAG_name() which returns
+        the tag as a string (through a pointer argument).
+      * dwarf.h: The first word of a comment is now capitalized (1 place).
+      * common.c: New, used by gennames.c.
+      * common.h: New, used by gennames.c
+      * Makefile.in: Now contains changes which build and run
+        gennames and create dwarf_names.o (which is part
+        of libdwarf).
+      * libdwarf2.1.mm: Document the new libdwarf functions.
+      * libdwarf2.1.pdf: Regenerated as rev 1.76, 6 June 2009.
+2009-06-05  DavidAnderson <davea42@earthlink.net>
+      * dwarf.h: added new DWARF4 attribute (etc) defines.
+2009-05-10  DavidAnderson <davea42@earthlink.net>
+      * dwarf_frame.c: Remove use of DW_FRAME_UNDEFINED_VAL in
+        favor of the value in the dbg structure.
+        Adding comments about the meaning of an error case.
+2009-05-07  DavidAnderson <davea42@earthlink.net>
+      * Makefile.in: Ensure temp files all get deleted.
+2009-05-04  DavidAnderson <davea42@earthlink.net>
+      * dwarf_die_deliv.c: Update _dwarf_get_size_of_val() 
+        call (with its new address_size argument).
+      * dwarf_frame.c: Use the new ci_address_size instead
+        of de_pointer_size.
+      * dwarf_frame.h: Added  ci_address_size to cie
+        in preparation for this value in DWARF4.
+      * dwarf_util.h: Adding address_size functions
+        and arguments declarations  so address_size can vary by CU.
+      * dwarf_util.c: Adding address_size functions
+        and arguments so address_size can vary by CU.
+      * dwarf_loc.c: Adding function dwarf_loclist_from_expr_a()
+        as a version with an address size argument.
+      * dwarf_frame2.c: Now initializes new ci_address_size field.
+      * dwarf_line.c: Now uses address size for CU instead of
+        default de_pointer_size.
+      * dwarf_ranges.c: File left out of svn before.
+        Implements dwarf_get_ranges() and dwarf_get_ranges_a(),
+        the latter is new with address size passed in via a DIE pointer.
+      * dwarf_arange.c: Added commentary. Removed erroneous
+        insistence that every aranges group have the same
+        address_size as the main elf object.
+      * dwarf_query.c: Adding address size to internal calls.
+      * dwarf_print_lines.c: Added '(file number is %d)' 
+        to -l -v -v -v output as the
+        file number and traditional C zero-origin index index of a 
+        line table header are not the same value
+        (see DWARF3 documentation, the end of section 6.2.5.3).
+      * libdwarf2.1.mm: Documented dwarf_loclist_from_expr_a()
+         and  dwarf_get_ranges_a().
+      * libdwarf2.1.pdf: Regenerated.
+      * libdwarf.h: Add commentary.
+        Add   dwarf_loclist_from_expr_a() and
+        dwarf_get_ranges_a() interfaces so address_size passed in.
+2009-04-04  DavidAnderson <davea42@earthlink.net>
+      * libdwarf.h, dwarf_frame.c: Added dwarf_set_frame_cfa_value().
+        Added dwarf_set_frame_rule_initial_value() as proper

+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+ 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
+
+  <signature of Ty Coon>, 1 April 1990

+
+That's all there is to it!

+  Fundamentally such code must treat a section index of 0 as
+  a real but empty section with no name (an empty name).
+  dwarf_elf_access.c and dwarf_elf_init_finish.c have some comments
+  on this point now.
+March 29,2011
+  All the code changed a lot because indentations were all over
+  the map, now they are consistent.  
+  Additions were made to DWARF4 support.
+  Now we use dicheck (a new open source application) to check indentation.
+  Library users will not see any change, all interfaces remain
+  as before.
+January 12,2010
+  A libdwarf user has noticed that the April 4, 2009 
+  consumer function changes introduced
+  a problem:  the default CFA column was DW_FRAME_CFA_COL
+  even when a newer DWARF3 consumer frame interface like 
+  dwarf_get_fde_info_for_all_regs3() is used.  The 
+  libdwarf2.1.pdf documentation
+  stated the default should be DW_FRAME_CFA_COL3 in that case.
+
+  The introduction of a caller-specified  frame-column
+  function (dwarf_set_frame_cfa_value())
+  in that April 4, 2009 release was flawed in that it failed 
+  to match the documentation.
+  
+  Now the default frame column is DW_FRAME_CFA_COL3 unless 
+  the configure option  --enable-oldframecol
+  is used at libdwarf build time.
+  If you are using libdwarf old frame consumer interfaces 
+  dwarf_get_fde_info_for_reg(), dwarf_get_fde_info_for_cfa_reg(), 
+  and dwarf_get_fde_info_for_all_regs() and want unchanged operation
+  then please configure libdwarf with --enable-oldframecol .
+  or add the call dwarf_set_frame_cfa_value(dbg,DW_FRAME_CFA_COL)
+  after calling a libdwarf initialization function.
+  It is impossible to configure a single libdwarf.a so that
+  it transparently defaults to both DW_FRAME_CFA_COL
+  and DW_FRAME_CFA_COL3.
+  
+  A call such as dwarf_set_frame_cfa_value(dbg,DW_FRAME_CFA_COL3)
+  or dwarf_set_frame_cfa_value(dbg,DW_FRAME_CFA_COL)
+  (or some other name/value of your choosing)
+  following the dwarf_init() call gives your application
+  full control of the frame cfa column independent of the libdwarf
+  configure option.  See the libdwarf2.1.pdf documentation for details.
+  We strongly recommend that you use dwarf_set_frame_cfa_value()
+  to avoid a configure-time dependency.
+  
+July 7, 2009
+  Implemented support for elf 'rela' relocations so libdwarf and dwarfdump
+  can read *nix .o files with such relocations reasonably, 
+  at least for some machines
+  (see dwarf_elf_access.c for EM_  in 'case' statements.)
+  This changes the binary access for non-Elf object users (folks
+  who have coded there own non-Elf access routines do reference
+  internals of dwarf_opaque.h), but the new data can be left zero
+  and the rest of the code should work fine.
+  dwarf_opaque.h gathers section data in Dwarf_Section_s structs
+  which simplifies the code in dwarf_init_finish.c and clarifies
+  what fields are section related.
+July 4, 2009
+  When something erroneous is detected in a die
+  information about the CU context may be of interest.
+  So we added dwarf_CU_dieoffset_given_die(), a function which allows
+  clients to find the relevant CU die for any die.  
+  The consumer can use normal attribute access functions to 
+  print information about that CU die (and the erroneous die,
+  of course).  See the libdwarf consumer document for more
+  information.
+April 27, 2009
+  Interface additions: dwarf_loclist_from_expr_a() and
+  dwarf_get_ranges_a() are new interfaces like
+  dwarf_loclist_from_expr() and dwarf_get_ranges() respectively,
+  but with arguments allowing
+  full support for different CIEs
+  in an executable  having different address-sizes
+  (and their compilation unit DIEs if .debug_info is present).
+  dwarf_get_loclist_entry() does not support
+  differing address sizes per CIE/CU.
+April 4, 2009
+  Added new functions dwarf_set_frame_cfa_value()
+  dwarf_set_frame_same_value(), and
+  dwarf_set_frame_undefined_value(). These are essential
+  for ABIs where the real register numbers exceed 1033
+  (such as ppc).  Failing to use these leads to 
+  frame instructions  DW_CFA_undefined and
+  DW_CFA_same_value emitting values that cannot be
+  interpreted correctly by a libdwarf consumer.
+  See dwarfdump for examples of use.
+Feb 14, 2009
+  Added configure option --enable-nonstandardprintf
+  which makes it easy to get printf of Dwarf_Unsigned (etc)
+  types correct even for non-standard compilers.
+Dec 30, 2008
+  Added interfaces for getting and printing the .debug_ranges
+  data.
+Dec 8, 2008
+  Record the abbreviation 'code' (index) in each DIE.
+  Making it possible for a pretty-printer to print the 
+  abbreviation code.
+Sep 30, 2008
+  Phil Mucci provided an a.out test chase which demonstrates a bug
+  in 64bit DWARF2 output by gcc.   Now libdwarf works around this
+  and with -v -v -v -v prints a warning.
+Sep 29, 2008
+  Thanks to Phil Mucci for providing a little-endian 64bit
+  test object file that exposed a problem when there are 'extra' bytes
+  (possibly unused) after a line table prologue header and before the
+  line table itself.  This releases fixes the bug.
+
+  Thanks to Matthew Legendre for pointing out that we were sharing
+  de_fde_count for eh and non-eh and that could cause erroneous
+  error returns in a couple of functions.
+  These counts are now separate.
+April 9, 2008
+  libdwarf would behave badly if one compilation unit had more than 64K
+  abbreviations: It was both very slow dealing with abbreviations and would
+  get mixed up and error-off.  Increased the size of some internal variables
+  and rewrote abbreviation lookup.
+February 18, 2008
+  It is now possible to write one's own access to objects, making it possible
+  to use a different library than libelf or even read a completely
+  different object format than ELF.
+  See dwarf_object_init() and see the new source files
+  dwarf_original_elf_init.c and dwarf_elf_access.c  for example
+  code using the new function-pointer approach as it's implementation.
+  Thanks to Josh Fuhs for doing the design and 99% of the work to make
+  this happen.
+February 2, 2008
+  Now pro_init() defaults to standard DWARF3 generated offset sizes.
+  But if a new flag DW_DLC_OFFSET_SIZE_64 or'd into flags passed to
+  dwarf_produser_init() or dwarf_producer_init_b, 
+  the DWARF3 extended offset size is generated (if the address size
+  is 64 bit).
+  The new configure option  --enable-dwarf-format-strict-32bit 
+  forces pro_init() to always cause 32bit offset dwarf generation.
+  The new configure option --enable-dwarf-format-sgi-irix forces
+  the old SGI IRIX 64bit offset generation for 64bit pointer size objects.
+
+  This is intended to simplify standard DWARF3 generation with
+  the now-normal use of 32bit DWARF offsets for both 32 and 64
+  bit pointer objects.
+ 
+  It does require that anyone wanting SGI IRIX dwarf generation
+  with its non-standard offsets for 64bit objects use the new
+  --enable-dwarf-format-sgi-irix configure time option.
+
+  This has no effect on dwarf reader code. It affects code calling
+  the libdwarf producer interfaces.
+
+December 8, 2007
+  Had to add an ugly configure conditional as libelf has
+  unconditional use of off64_t in recent libelf.h
+July 3, 2007
+  A new interface function, dwarf_loclist_from_expr(),
+  allows easy extraction of dwarf expression bytes from
+  expressions in frame data.
+May 8, 2007
+  Now documents released as .mm and .pdf (no longer as .ps).
+May 7, 2007
+  Incorporates Sun Microsystems  extensions to dwarf.h and
+  to the consumer and producer libraries.   The changes
+  include corrections so the producer library  cleans up it's memory
+  use on a call to dwarf_producer_finish(dbg).
+  Thanks to Chris Quenelle of Sun for these contributions.
+
+March 20, 2007
+  nroff/troff and the AT&T -mm package are not widely available,
+  so now the Makefile refers to groff, which works quite nicely.
+
+February 20, 2007
+  Documented libdwarf thread safety in README.
+  Fixed memory leak in  dwarf macro reading code.
+  Removed use of static data in dwarf macro
+  reading code: now uses stack/heap (for
+  thread safety).
+
+February 9, 2007
+  Maintenance of libdwarf is now outside SGI
+  as David Anderson has left SGI.
+
+March 29, 2006
+  The March  27, 2006 version accomodates DWARF3.
+  Some people have been using the library without
+  altering dwarf.h, libdwarf.h to accomodate
+  large numbers of registers.  This exposed a bug
+  (an off-by-one error) but also makes it clear
+  additional documentation is needed.  So 
+  in libdwarf large new comments near 'TARGET DEPENDENCY'
+  attempt to explain better.
+Oct 03, 2005
+  The July version had an incompatible interface: old
+  dealloc code did not always work right. The incompatibility
+  is now fixed and the new features remain.
+
+July 15, 2005
+  New optional alloc-check code optionally checks all
+  allocated memory is freed (malloc_check.h malloc_check.c)
+  Various new dealloc routines written as the previous approach
+  of letting client code do detailed dealloc turned out not
+  to dealloc all memory.
+  To get the new checking you must manually change a line
+  in malloc_check.h and rebuild libdwarf.
+
+
+Mar 31, 2005
+  Documented  the libexc.so/.debug_funcnames
+  dependency and the 64bit-offset DWARF extension in
+  mips_extentions.{mm,ps}.
+
+Mar 21, 2005
+  gcc 3.3 and 3.4 .eh_frame 'z' augmentations are not handled
+  correctly, so libdwarf gives an error when attempting to
+  print such. gcc 2 'eh' augmentation is simpler and
+  prints correctly.  (.eh_frame is a GNU section,
+  not DWARF2/3, and what is recorded in .eh_frame is not
+  specified by DWARF2/3, though .eh_frame does resemble
+  DWARF2/3 .debug_frame).
+
+
+Oct 28, 2004
+  Updated contact address in copyright: SGI moved 1/4 mile
+  in 2003 to a new address: 1500 Crittenden Lane.
+  
+  Documented additional vendor extensions.
+
+Oct 27, 2004
+  Added known vendor extensions to dwarf2/3 to dwarf.h
+  HP, GNU, PGI and UPC extensions are now recorded.
+  Recorded vendor extensions from Concurrent.
+
+Feb 3, 2004
+  If 'Dwarf_Word' is 64 bits, two macros reading leb numbers
+  fail to initialize upper bits of the values read.
+  First noticed with bogus line numbers printing from dwarfdump.
+  Now we use already-existing functions, avoiding the problem.
+
+Oct 02, 2003
+  Support .debug_loc section fully.
+
+Sept 29, 2003
+  Support DW_FORM_indirect properly.
+  Supports loclists in part (but not multiple loclist entries yet).
+  Support 'padding bytes' at end of .debug_arange and
+  .debug_pubnames and .debug_pubtypes per CU
+  (recent dwarf committee email made it clear this is appropriate).
+
+May 23, 2002
+  Libdwarf now asks for sections only when they are
+  used, so that unneeded sections aren't loaded.
+  Support for using SGI's ELF library as an alternative to
+  using AT&T libelf-style has been added (the SGI ELF
+  library is presently only available internally to SGI).
+
+Jan 10, 2002
+  Fixed memory leak in dwarf_finish().
+
+Aug 21, 2001
+  If one called dwarf_add_file_decl()
+  or dwarf_add_directory_decl() but never added a line,
+  .debug_line was not produced.  This was a mistake,
+  as if any file or directory was provided .debug_line
+  should be produced. Now it is produced.
+
+June 14, 2001
+  Given a cu header offset, it was not easy to derive the
+  CU header DIE offset. Created the new
+  function dwarf_get_cu_die_offset_given_cu_header_offset()
+  do get the CU header DIE offset.
+  Added the function dwarf_get_arange_cu_header_offset()
+  so the cu header offset could be retrieved from .debug_aranges
+  information.
+
+June 07, 2001
+  Major bug in dwarf_leb.c decoding large integers 
+  (Dwarf_Signed 64 bit where library is compiled in ILP32) 
+  found and fixed.
+
+May 21, 2001
+  Some small fixes have been found by various folks,
+  so it seems time to prepare a new source release.
+  See ChangeLog for details.
+
+April 15, 2000
+  The libdwarf copyright has changed to
+     version 2.1 of the GNU Lesser General Public License.
+  Anyone holding a version of libdwarf that was published
+  before this new copyright is allowed to use
+    the copyright published in that earlier libdwarf source
+    on the earlier source
+  or to use 
+    this new copyright on the earlier source,
+  at their option.
+
+
+December 08, 1999
+  The dwarf committee has adopted the offset-extension
+  proposal. This allows compatibly emitting
+  dwarf with 64bit offsets.
+
+  The dwarf reader now automatically figures out which is in use.
+  The dwarf writer configures itself at the time the
+  writer initialization routine is called, though
+  the writer is restricted, at libdwarf 
+  compile time, to one of
+		mips/sgi pure 32/pure 64 offsets/pointers.
+
+		32bit offsets only (per dwarf 2.0.0 and cygnus)
+
+		32bit offsets with extension to 64bit offsets
+		allowed (the offset-extension newly passed).
+  
+  In addition, a great deal of duplicate code
+  for the sgi  .debug_weaknames, .debug_funcnames, 
+  .debug_varnames and .debug_typenames sections has
+  been removed: a single set of functions does the real work now.
+  
+Sept 29, 1999
+  Just found out that cygnus is, on 64bit targets, generating
+  32bit offsets (as elf32 has, for example) with 64 bit
+  pointers (in references to text and data).
+  Whereas sgi has always generated 64bit dwarf with
+  64 bit offsets (as in elf64) and 64bit pointers for
+  64bit pointer objects.
+  I'll call the sgi approach 64-bit and the cygnus approach
+  32bit-offsets.
+
+  Cygnus is following the DWARF2 spec as written, so they are
+  right in doing only 32bit-offsets.
+
+  Folks at sgi (including me) think that, as for elf64,
+  the offsets in dwarf for 64bit pointer-apps should be
+  64 bits.  We think it is only a matter of time
+  before we really *need* 64bit offsets and when that happens
+  it will be on an important app.  Disk space is cheap,
+  so lets just go 64 bit on 64bit apps (such as ia64 apps)
+  to avoid a future problem.
+  I(davea@sgi.com) think the 'pointer-size' references in the dwarf
+  spec were really written for 64-bit pointer apps.
+  I don't recall serious consideration of 64bit pointer
+  apps in the committee deliberations (I did miss
+  a couple of meetings) and think 64bit offsets
+  are consistent with dwarf2, even though the speci
+  was not written for such. We think true full 64 bit
+  dwarf2 is the right way to go (the spec changes
+  are obvious: file and section offsets become 64bit
+  with 64bit pointer objects.
+ 
+  MIPS/SGI is definitely 64-bit offsets for 64 bit objects,
+  cygnus is definitely 32bit-offsets for earlier 64bit pointer
+  environments.
+
+  At any rate, now the dwarf reader allows and accomodates
+  both and the dwarf producer also accomodates both.
+  Some tweaking of the pro_init.c or dwarf_init_finish.c
+  files may be necessary in future: no other changes should
+  be needed to accomodate the two 64bit approaches, as
+  the library (and dwarfdump) now deal with both forms.
+
+
+August 20, 1999
+  Added some #ifndef/#define to pro_util.h to let libdwarf build
+  on more hosts.  (since those hosts don't need the producer
+  code, AFAIK, zero values suffice for missing #defines.)
+
+July 21, 1999
+  Now reader transparently reads either-endianness data
+  from an either-endianness object.
+  Updated dwarf.h and libdwarf.h to recognize
+  GNU egcs dwarf extensions and to print the egcs eh_frame
+  section.
+
+June 10, 1999
+  gnu configure version of libdwarf made available for the
+  first time.  
+  Still allows only same-endian-as-host in objects.
+  
+August, 1994
+  libdwarf source made available for ftp on sgigate.sgi.com
+	/ftp/pub
+
+June, 1994
+  Consumer interface changed completely, following
+  "Candy Machine Interfaces" chapter from
+   "Writing Solid Code" by Steve Maguire (Microsoft Press).
+
+April,  1993
+  Initial version of libdwarf  for dwarf version 2
+  written at sgi.

+No real install target is provided here, so 'make install' does
+not do much. One can copy either or both of libdwarf.a libdwarf.so 
+to somewhere fairly standard (but intended for software you build)  
+like '/usr/local/lib'.  Or anywhere else you want to copy it.
+
+To use dwarf or libdwarf, you may want to copy dwarf.h and
+libdwarf.h somewhere convenient (possibly /usr/local/include), 
+and you may need to copy the libdwarf to a convenient spot 
+(/usr/local/lib is a traditional place for libraries one builds
+oneself on Unix and Linux).
+This copying is not needed to build dwarfdump.
+
+
+Multi Threading, or using threads with libdwarf (Thread Safety):
+  Nothing in libdwarf does any locking.  Every Dwarf_Debug
+  (such as returned by dwarf_init()) is fully independent
+  of all other Dwarf_Debug-s.  However, calls to libdwarf can
+  change a Dwarf_Debug. So it is unsafe to have two different
+  threads accessing a single Dwarf_Debug simultaneously.
+  It is therefore sufficient to ensure than any one Dwarf_Debug
+  is only accessed from a single thread.
+
+Warnings like
+ "warning: cast from pointer to integer of different size"
+at compile time are to be expected in dwarf_frame.c and
+dwarf_frame2.c.   Do not be alarmed.
+
+If your headers are not in the expected places,
+use the make command line to add flags and include directories.
+For example
+  ./configure  
+  PREINCS="-I /usr/local/share/include" POSTINCS="-I /home/x/include"  make
+PREINCS content is inserted before CFLAGS as make(1) is running.
+POSTINCS content is added after the CFLAGS value.
+
+To set LDFLAGS (which is used when building a .so and
+in building gennames to create some source here), 
+do so at configure time, for example:
+  ./configure LDFLAGS="-L /var/tmp"
+Or use PRELIBS and/or POSTLIBS at 'make' time similar to the use
+of PREINCS and POSTINCS.
+
+If you are using the old frame interfaces and depend on
+the use of DW_FRAME_CFA_COL you must add  --enable-oldframecol
+to the ./configure options to configure libdwarf.
+See NEWS and libdwarf2.1.mm/pdf .
+
+To generate SGI IRIX 64 bit offsets (in the producer code)
+configure with   --enable-dwarf-format-sgi-irix.
+To configure with only 32bit offsets (aka DWARF2) configure
+with --enable-dwarf-format-strict-32bit.
+By default the producer now generates 32bit offsets by default
+but one can turn on DWARF3 64bit offset generation at runtime by ORing
+DW_DLC_OFFSET_SIZE_64 onto the flags in the call to 
+dwarf_producer_init() (or dwarf_producer_init_b) [when the
+address size is specified as 64 bit].
+
+Mac OSX (June 2010): Since MacOSX does not use elf, there is no elf.h
+header in the headers provided on MacOSX.
+Use a search engine (like google) to find an elf.h you can use.
+http://www.rockbox.org/tracker/9006?getfile=16683 
+might be useful.
+In addition, the archive (ar) program on MacOSX does not
+automatically generate some data so modify the generated
+Makefile to add -s to the options to ar.
+
+To enable dection of Windows pathnames as full paths
+add --enable-windowspath.  Doing this does mean things like
+A:foo and \anything are treated as full paths (these are
+unlikely path names on a POSIX system but are legal 
+POSIX partial paths).
+
+It is possible to request a shared library (libdwarf.so) build with
+	--enable-shared
+To turn off the build of the archive library (libdwarf.a) specify
+        --disable-nonshared
+but in this case you must specify --enable-shared or nothing will
+build!
+
+TARGET DEPENDENCIES of .debug_frame:
+dwarf.h
+  These should be revised if you have more than the defined
+  63 'normal' registers.  It's not harmful to have these too large!
+  Too small will lead to errors reading .debug_frame and .eh_frame.
+  DW_FRAME_HIGHEST_NORMAL_REGISTER
+  DW_FRAME_LAST_REG_NUM
+
+  These you might revise, but can safely ignore if simply
+  using dwarfdump.  If using the producer code you will want
+  to get these exactly right for your architecture.
+  DW_FRAME_RA_COL
+  DW_FRAME_STATIC_LINK
+  DW_FRAME_CFA_COL 
+
+libdwarf.h
+  The DW_FRAME_REG_INITIAL_VALUE #define should be set to
+  the value appropriate to your architecture. See libdwarf.h
+  for details.
+
+  If DW_REG_TABLE_SIZE is not set large enough attempts to 
+  fill in the .debug_frame tables will get an error. 
+  Should be at least as large as DW_FRAME_LAST_REG_NUM.
+  If it's too large nothing is harmed (but some extra space taken
+  at run time).
+
+If your printf does not support C standard %llx etc,
+(such as MSWindows with long long), configure
+option --enable-nonstandardprintf
+and defines like DW_PR_DUx etc in libdwarf.h
+provide a way to configure for that relatively easily.
+
+
+The .debug_frame is so very architecture dependent
+and because the host (where libdwarf/dwarfdump are executed)
+and target (the objects read) could be different.
+It's currently not supported to have dwarfdump/libdwarf determine
+the architecture on-the-fly and do-the-right-thing.
+Just setting DW_FRAME_LAST_REG_NUM and DW_FRAME_HIGHEST_NORMAL_REGISTER
+and DW_REG_TABLE_SIZE high enough will likely suffice for most
+purposes and most compilers/architectures..
+See comments in dwarf.h/libdwarf.h.
+
+It's perfectly safe to ignore the above suggestions as long
+as libdwarf does not get a DW_DLE_DF_REG_NUM_TOO_HIGH error.
+(which would only happen on reading .debug_frame or .eh_frame data).
+
+If you intend to use the libdwarf dwarf-producer code
+for .debug_frame information
+you must do a thorough analysys and revise dwarf.h
+substantially to match the output target architecture.
+
+In general, in the producer code, numbers are copied from and
+to integers with memcpy().  In case of endianness problems,
+constants set in dwarf_producer_init() can fix the problems.
+If one wants to produce a *different-endian* output the best
+solution is to change the integer memcpy calls to call thru a
+new dbg-based function pointer and have it 'do the right thing'
+to adjust endianness.  Set the function pointer correctly in
+dwarf_producer_init() and the rest of the code will just call
+thru the function pointer.  Tedious work to find and change the
+memcpy calls to be dbg->de_memcpy(), but once done the code is
+no longer endian dependent (right now there is no way to ask
+for cross-endian: a new flag needed or ?).
+
+leb128 numbers are endian-independent, so nothing need be
+done with those for cross-endian support (the storage
+of leb128 on disk is always little-endian).
+
+The .ps files are postscript. So those who cannot deal with mm
+format files but do have a postscript printer (or have
+ghostscript) can print the documents.  
+This form was chosen before pdf format existed...

+\`configure' configures this package to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+

+  --enable-dwarf-format-strict-32bit
+                          Force producer to generate only DWARF format 32bit.
+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+
+    Extensions part of DWARF4 are marked DWARF4.
+
+    A few extension names have omitted the 'vendor id'
+    (See chapter 7, "Vendor Extensibility"). Please
+    always use a 'vendor id' string in extension names.
+
+    Vendors should use a vendor string in names and

+.HU "FOREWORD"
+This document specifies the second generation of symbolic debugging
+information based on the DWARF format that 
+has been developed by the \*(iX
+Programming Languages Special Interest Group (SIG).
+It is being circulated for industry review.  
+The first version of the DWARF specification was published
+by \*(iX in January, 1992.  The current version adds significant
+new functionality, but its main thrust is to achieve a much
+denser encoding of the DWARF information.  Because of the new
+encoding, DWARF Version 2 is not binary compatible with
+DWARF Version 1.
+.P 
+At this point, the SIG believes that this document sufficiently
+supports the debugging needs of C, C++, FORTRAN 77, 
+Fortran90, Modula2 and Pascal, and we have
+released it for public comment.  We will accept comments on this
+document until September 30, 1994.  Comments may be directed via email
+to the SIG mailing list (plsig@ui.org).  If you are unable
+to send email, paper mail, FAX, or machine readable copy 
+on \*(aX, MS-DOS, or Macintosh compatible media can be 
+sent to \*(iX at the address listed below, 
+and will be forwarded to the SIG.

+.H 1 "INTRODUCTION"
+\fR
+This document defines the format for the information generated by
+compilers, assemblers and linkage editors that is necessary for symbolic,
+source-level debugging.  The debugging information format does not favor the
+design of any compiler or debugger.  Instead, the goal is to create a method of
+communicating an accurate picture of the source program to any debugger in a
+form that is economically extensible to different languages while retaining
+backward compatibility.
+.P
+The design of the debugging information format is open-ended, allowing for the
+addition of new debugging information to accommodate new languages or
+debugger capabilities while remaining compatible with other languages or
+different debuggers.
+.H 2 "Purpose and Scope"
+The debugging information format described in this document is designed to
+meet the symbolic, source-level debugging needs of 
+different languages in a unified fashion by
+requiring language independent debugging information whenever possible.
+.IX C++ %caa
+.IX virtual functions
+.IX Fortran
+Individual needs, such as C++ virtual functions or Fortran common blocks are
+accommodated by creating attributes that are used only for those
+languages.  The \*(iX \*(tE believes 
+that this document sufficiently covers the 
+.IX languages
+debugging information needs of C, C++, FORTRAN77, Fortran90, 
+Modula2 and Pascal.
+.IX C %c
+.IX Modula2
+.IX Pascal
+.IX FORTRAN77
+.IX Fortran90
+.P
+This document describes DWARF Version 2, the second generation of debugging
+.IX Version 2
+information based on the DWARF format.  While DWARF Version 2 provides
+new debugging information not available in Version 1, the primary focus
+of the changes for Version 2 is the representation of the information,
+rather than the information content itself.  The basic structure of 
+the Version 2 format remains as in Version 1: the debugging information
+is represented as a series of debugging information entries, each containing
+one or more attributes (name/value pairs). 
+.IX debugging information entries
+.IX attributes
+The Version 2 representation, however,
+is much more compact than the Version 1 representation.
+.IX Version 1
+In some cases, this greater density has been achieved at the expense
+of additional complexity or greater difficulty in producing and processing
+the DWARF information.  We believe that the reduction in I/O and in
+memory paging should more than make up for any increase in processing time.
+.P
+Because the representation of information has changed from Version 1 to
+Version 2, Version 2 DWARF information is not binary compatible
+.IX compatibility
+with Version 1 information.  To make it easier for consumers to
+support both Version 1 and Version 2 DWARF information, the Version
+2 information has been moved to a different object file section,
+.Cf .debug_info .
+.IX \f(CW.debug_info\fP %debugai
+.P
+The intended audience for this document are the developers of 
+both producers and consumers of debugging information, typically
+language compilers, debuggers and other tools that need to interpret
+a binary program in terms of its original source.
+.H 2 "Overview"
+There are two major pieces to the description of the DWARF format in
+this document.  The first piece is the informational content
+of the debugging entries.  The second piece
+is the way the debugging information is encoded and 
+represented in an object file.
+.P
+The informational content is described in sections two
+through six.
+Section two describes the overall structure of
+the information and attributes that are common to many or all of
+the different debugging information entries.  
+Sections three, four and five describe the specific debugging
+information entries and how they communicate the
+necessary information about the source program to a debugger.
+Section six describes debugging information contained
+outside of the debugging information entries, themselves.
+The encoding of the DWARF information is
+presented in section seven.
+.P
+Section eight describes some future directions for the DWARF
+specification.
+.P
+In the following sections, text in normal font describes required aspects
+of the DWARF format.  Text in \fIitalics\fP is explanatory or supplementary 
+material, and not part of the format definition itself.
+.H 2 "Vendor Extensibility"
+.IX vendor extensions
+This document does not attempt to cover all interesting languages or even
+to cover all of the interesting debugging information needs for its primary
+target languages (C, C++, FORTRAN77, Fortran90, Modula2, Pascal). 
+Therefore the document provides
+vendors a way to define their own debugging information tags, attributes,
+base type encodings, location operations, language names,
+calling conventions and call frame instructions
+by reserving a portion of the name space and valid values 
+for these constructs for vendor specific additions.  Future versions
+of this document will not use names or values reserved for vendor specific
+additions.  All names and values not reserved for vendor additions, however,
+are reserved for future versions of this document.  See section 7 for
+details.
+.H 2 "Changes from Version 1"
+The following is a list of the major changes made to the DWARF Debugging
+Information Format since Version 1 of the format was published (January
+.IX Version 1

+.H 1 "GENERAL DESCRIPTION"
+.H 2   "The Debugging Information Entry"
+DWARF uses a series of debugging information entries to define a
+.IX debugging information entries
+low-level representation of a source program. Each debugging
+information entry is described by an identifying tag and
+contains a series of attributes. 
+The tag specifies the class to which an entry
+belongs, and the attributes define the specific characteristics
+of the entry.
+.P
+.nr aX \n(Fg+1
+The set of required tag names is listed in Figure \n(aX.
+.IX tags
+The debugging information entries they identify are described in sections three, four and five.
+.P
+The debugging information entries in DWARF Version 2 are intended
+to exist in the 
+.Cf .debug_info
+section of an object file.

+.P
+The permissible values for an attribute belong to one or more classes
+.IX attributes, values
+.IX attributes, forms
+of attribute value forms.  Each form class may be represented in one or more
+ways.  For instance, some attribute values consist of a single piece
+of constant data.  ``Constant data'' is the class of attribute value
+that those attributes may have.  There are several representations
+of constant data, however (one, two, four, eight bytes and variable
+length data).  The particular representation for any given instance
+of an attribute is encoded along with the attribute name as part
+of the information that guides the interpretation of a debugging
+information entry.   Attribute value forms may belong
+to one of the following classes.
+.VL 18
+.LI address
+.IX attributes, addresses
+Refers to some location in the address space of the described program.
+.LI block
+.IX attributes, blocks
+An arbitrary number of uninterpreted bytes of data.
+.LI constant
+.IX attributes, constants
+One, two, four or eight bytes of uninterpreted data, or data encoded
+in the variable length format known as LEB128 (see section 7.6).
+.IX variable length data
+.IX LEB128
+.LI flag
+.IX attributes, flags
+A small constant that indicates the presence or absence of an attribute.
+.LI reference
+.IX attributes, references
+Refers to some member of the set of debugging information entries that describe
+the program.  There are two types of reference.  The first is an
+offset relative to the beginning of the compilation unit in
+which the reference occurs and must refer to an entry within
+that same compilation unit.  The second type of reference
+is the address of any debugging information entry within
+the same executable or shared object; it may refer to an entry
+in a different compilation unit from the unit containing the
+reference.
+.LI string
+.IX attributes, strings
+A null-terminated sequence of zero or more (non-null) bytes.
+Data in this form are generally printable strings.  Strings
+may be represented directly in the debugging information entry
+or as an offset in a separate string table.
+.LE
+.P
+There are no limitations on the ordering of attributes within a debugging
+.IX attributes, ordering
+information entry, but to prevent ambiguity,
+no more than one attribute with a given name may appear in any debugging
+information entry.
+.H 2 "Relationship of Debugging Information Entries"
+.I
+A variety of needs can be met by permitting a single debugging
+information entry to ``own'' an arbitrary number of other debugging
+entries and by permitting the same debugging information entry to be
+one of many owned by another debugging information entry.
+This makes it possible to describe, for example,
+the static block structure within
+a source file, show the members of a structure, union, or class, and associate
+declarations with source files or source files with shared objects.
+.P
+.R
+The ownership relation
+of debugging information entries is achieved naturally
+.IX debugging information entries
+because the debugging information is represented as a tree.
+The nodes of the tree are the debugging information entries
+themselves.  The child entries of any node are exactly those
+.IX debugging information entries, child entries
+debugging information entries owned by that node.\*F
+.FS
+While the ownership relation of the debugging information
+entries is represented as a tree, other relations among
+the entries exist, for example, a pointer from an entry
+representing a variable to another entry representing
+the type of that variable.  If all such relations are
+taken into account, the debugging entries form a graph,
+not a tree.
+.FE
+.P
+The tree itself is represented by flattening it in prefix
+order.  Each debugging information entry
+is defined either to have child entries or not to have child entries
+(see section 7.5.3).
+If an entry is defined not to have children, the next physically
+succeeding entry is the sibling of the prior entry.  If an entry
+.IX debugging information entries, siblings
+is defined to have children, the next physically succeeding entry
+is the first child of the prior entry.  Additional children of the parent
+entry are represented as siblings of the first child.  A chain
+of sibling entries is terminated by a null entry.
+.IX debugging information entries, null entries
+.P
+In cases where a producer of debugging information
+feels that it will be important for consumers of that information
+to quickly scan chains of sibling entries, ignoring the children
+of individual siblings, that producer may attach an
+.Cf AT_sibling
+attribute to any debugging information entry.  The value of
+this attribute is a reference to the sibling entry of the
+entry to which the attribute is attached.
+.H 2 "Location Descriptions"
+.I
+The debugging information must provide consumers a way to find the location
+of program variables, determine the bounds of dynamic arrays and strings
+and possibly to find the base address of a subroutine's stack frame or
+the return address of a subroutine.  Furthermore, to meet the needs
+of recent computer architectures and optimization techniques, the debugging
+information must be able to describe the location of an object
+whose location changes over the object's lifetime.
+.P
+.R
+Information about the location of program objects is provided by
+location descriptions.  Location
+.IX locations, descriptions
+descriptions can be either of two forms: 
+.AL
+.LI
+\fILocation expressions\fP which are a language independent representation of 
+addressing rules
+.IX locations, expressions
+of arbitrary complexity built from a few basic
+building blocks, or \fIoperations\fP.  They are sufficient for describing
+the location of any object as long as its lifetime is either static
+or the same as the lexical block that owns it, and it does not move throughout 
+its lifetime.  
+.LI
+\fILocation lists\fP which are used to describe objects that 
+.IX locations, lists
+have a limited lifetime or change their location throughout their
+lifetime.  Location lists are more completely described below.
+.LE
+.P
+The two forms are distinguished in a context sensitive manner.  As the value
+of an attribute, a location expression is 
+encoded as a block and a location list is encoded as a constant offset into
+a location list table.
+.P
+.I
+Note: The Version 1 concept of "location descriptions" was replaced in Version 2 
+with this new abstraction because it is denser and more descriptive.  
+.IX Version 1
+.IX Version 2
+.R
+.H 3 "Location Expressions"
+A location expression consists of zero or more location operations.
+.IX locations, expressions
+An expression with zero operations 
+is used to denote an object that is
+present in the source code but not present in the object code
+(perhaps because of optimization).  
+.IX optimized code
+The location operations fall into two categories, register names and
+addressing operations.  Register names always appear alone and indicate
+that the referred object is contained inside a particular 
+register.  Addressing operations are memory address computation 
+rules.  All location operations are encoded as a stream of opcodes that
+are each followed by zero or more literal operands.  The number of operands
+is determined by the opcode.
+.H 3 "Register Name Operators"
+.IX locations, register name operators
+The following operations can be used to name a register.
+.P
+.I
+Note that the 
+register number represents a DWARF specific mapping of numbers onto
+the actual registers of a given architecture.
+The mapping should be chosen to gain optimal density and 
+should be shared by all users of a given architecture. 
+The \*(tE recommends
+that this mapping be defined by the ABI\*F
+.IX ABI
+.FS

+0 through 31, inclusive.  The object addressed is in register \fIn\fP.
+.LI
+.Cf DW_OP_regx
+.br
+The
+.Cf DW_OP_regx
+operation has a single unsigned LEB128 literal operand that encodes the 
+name of a register.
+.LE
+.H 3 "Addressing Operations"
+.IX locations, stack
+Each addressing operation represents a postfix operation on a simple stack 
+machine.  Each element of the stack is the size of an
+address on the target machine.
+The value on the top of the stack after
+``executing'' the location expression is taken to be the result (the address
+of the object, or the value of the array bound, or the length of a
+dynamic string).  In the case of locations used for structure members, 
+.IX members, locations
+the computation assumes that the base address of the containing structure
+has been pushed on the stack before evaluation of the addressing operation.
+.R
+.H 4 "Literal Encodings"

+.H 3 "Location Lists"
+.IX locations, lists
+Location lists are used in place of location expressions whenever

+during its lifetime.  Location lists are contained in a separate
+object file section called
+.Cf .debug_loc.
+.IX \f(CW.debug_loc\fP %debugalo
+A location list is indicated by a location
+attribute whose value is represented as a

+.Cf .debug_loc
+section to the first byte of the list for the object in question.
+.P
+Each entry in a location list consists of:
+.AL
+.LI
+A beginning address.  This address is relative to the base address
+of the compilation unit referencing this location list.  It marks
+the beginning of the address range over which the location is valid.
+.LI
+An ending address, again relative to the base address
+of the compilation unit referencing this location list.  It marks
+the first address past the end of the address range over 
+which the location is valid.
+.LI
+A location expression describing the location of the object over the
+range specified by the beginning and end addresses.
+.LE
+.P
+Address ranges may overlap.  When they do, they describe a situation
+in which an object exists simultaneously in more than one place.
+If all of the address ranges 
+in a given location list do not collectively cover the entire
+range over which the object in question is defined, it is assumed
+that the object is not available for the portion of the range that is not
+covered.
+.IX optimized code
+.P
+The end of any given location list is marked by a 0 for the beginning
+address and a 0 for the end address; no location description is present.
+A location list containing
+only such a 0 entry describes an object that exists in the source
+code but not in the executable program.

+.R
+.P
+Any debugging information entry that contains a description of the
+location of an object or subroutine may have a
+.Cf DW_AT_segment
+attribute, whose value is a location description.  The description
+evaluates to the segment value of the item being described.  If

+attribute, it inherits the segment value from its parent entry.
+If none of the entries in the chain of parents for this entry

+.IX declarations, non-defining
+.IX declarations, defining
+A debugging information entry representing a program object or type
+typically represents the defining declaration of that object or type.  In

+.H 2 "Identifier Names"
+.IX identifiers, names
+Any debugging information entry representing a program entity that

+attribute, whose value is a string representing the name as it appears
+in the source program.  A debugging information entry containing
+no name attribute, or containing a name attribute whose value consists

+.R
+.P
+The presence of low and high pc attributes in a compilation unit entry

+In C++ a subroutine may declare a set of types for which

+that subroutine may generate or ``throw'' an exception.
+.P
+.R
+If a subroutine explicitly declares that it may throw an

+represented by a debugging information entry with the tag
+.Cf DW_TAG_thrown_type .
+Each such entry is a child of the entry representing the
+subroutine that may throw this type.  All thrown type entries
+should follow all entries representing the formal parameters
+of the subroutine and precede all entries representing the
+local variables or lexical blocks contained in the subroutine.
+Each thrown type entry contains a

+attribute, whose value is a reference to an entry describing
+the type of the exception that may be thrown.
+.H 3 "Function Template Instantiations"
+.I
+.IX C++ %caa
+.IX templates
+In C++ a function template is a generic
+definition of a function that
+is instantiated differently when called with values
+of different types.  DWARF does not represent the generic
+template definition, but does represent each instantiation.
+.R
+.P
+A template instantiation is represented by a debugging information
+entry with the tag
+.Cf DW_TAG_subprogram .
+With three exceptions,
+such an entry will contain the same attributes and have the same
+types of child entries as would an entry for a subroutine 
+defined explicitly
+using the instantiation types.  The exceptions are:
+.AL
+.LI 
+Each formal parameterized type declaration appearing in the
+template definition is represented by a debugging information entry
+with the tag 
+.Cf DW_TAG_template_type_parameter .
+Each such entry has a 
+.Cf DW_AT_name
+attribute, whose value is a null-terminated
+string containing the name of the formal type parameter as it
+appears in the source program.  The template type parameter
+entry also has a 
+.Cf DW_AT_type
+attribute describing the actual type by
+which the formal is replaced for this instantiation.
+All template type parameter entries should appear before
+the entries describing the instantiated formal parameters
+to the function.
+.LI
+.IX compilation units
+If the compiler has generated a special compilation unit
+to hold the template instantiation and that compilation unit
+has a different name
+from the compilation unit containing the template definition,
+the name attribute for the debugging entry representing
+that compilation unit should be empty or omitted.
+.LI
+.IX declarations, coordinates
+If the subprogram entry representing the template instantiation
+or any of its child entries
+contain declaration coordinate attributes, those attributes

+.H 4 "Abstract Instances"
+For the remainder of this discussion,
+any debugging information entry that is owned (either directly or
+indirectly) by a debugging information entry that contains the 
+.Cf DW_AT_inline
+attribute will be referred to as an ``abstract instance entry.''
+Any subroutine entry that contains a

+attribute will be known as an ``abstract instance root.''
+Any set of abstract instance entries that are all children (either directly
+or indirectly) of some abstract instance root, together with the root itself,
+will be known as an ``abstract instance tree.''
+.P
+A debugging information entry that is a member of an abstract instance
+tree should not contain a

+.Cf DW_AT_return_addr , 
+.Cf DW_AT_start_scope ,
+or
+.Cf DW_AT_segment 
+attribute.
+.P
+.I
+It would not make sense to put these attributes
+into abstract instance entries since
+such entries do not represent actual (concrete) instances and thus
+do not actually exist at run-time.
+.P
+.R
+The rules for the relative location of entries belonging to abstract instance 
+trees are exactly
+the same as for other similar types of entries that are not abstract.
+Specifically, the rule that requires that an entry representing a
+declaration be a direct child of the entry representing the scope of
+the declaration applies equally to both abstract and
+non-abstract entries.  Also, the ordering rules for formal parameter entries,
+member entries, and so on, all apply regardless of whether or not a given entry
+is abstract.
+.H 4 "Concrete Inlined Instances"
+.IX subroutines, inlined
+Each inline expansion of an inlinable subroutine is represented
+by a debugging information entry with the tag
+.Cf DW_TAG_inlined_subroutine .
+Each such entry should be a direct child of the entry that represents the
+scope within which the inlining occurs.
+.P
+Each inlined subroutine entry contains a 
+.Cf DW_AT_low_pc
+attribute, representing the address of the first
+instruction associated with the given inline
+expansion.   Each inlined subroutine entry also contains a
+.Cf DW_AT_high_pc
+attribute, representing the
+address of the first location past the last instruction associated with
+the inline expansion.
+.P
+For the remainder of this discussion,
+any debugging information entry that is owned (either directly or indirectly)
+by a debugging information entry with the tag 
+.Cf DW_TAG_inlined_subroutine 
+will be referred to as a ``concrete inlined instance entry.''
+Any entry that has the tag 
+.Cf DW_TAG_inlined_subroutine
+will be known as
+a ``concrete inlined instance root.''
+Any set of concrete inlined instance entries that are all children (either
+directly or indirectly) of some concrete inlined instance root, together
+with the root itself, will be known as a ``concrete inlined instance
+tree.''
+.P
+Each concrete inlined instance tree is uniquely associated with one (and
+only one) abstract instance tree.
+.P
+.I
+Note, however, that the reverse is not true.  Any given abstract instance
+tree may be associated with several different concrete inlined instance
+trees, or may even be associated with zero concrete inlined instance
+trees.
+.P
+.R
+Also, each separate entry within a given concrete inlined instance tree is
+uniquely associated with one particular entry in the associated abstract
+instance tree.  In other words, there is a one-to-one mapping from entries
+in a given concrete inlined instance tree to the entries in the associated
+abstract instance tree.
+.P
+.I
+Note, however, that the reverse is not true.  A given abstract instance
+tree that is associated with a given concrete inlined instance tree
+may (and quite probably will) contain more entries than the associated
+concrete inlined instance tree (see below).
+.R
+.P
+Concrete inlined instance entries do not have most of the attributes (except
+for 
+.Cf DW_AT_low_pc , 
+.Cf DW_AT_high_pc ,
+.Cf DW_AT_location ,
+.Cf DW_AT_return_addr ,
+.Cf DW_AT_start_scope
+and
+.Cf DW_AT_segment )
+that such entries
+would otherwise normally have.  In place of these omitted attributes,
+each concrete inlined instance entry has a
+.Cf DW_AT_abstract_origin 
+attribute that 
+may be used to obtain the missing information (indirectly) from
+the associated abstract instance entry.  The value of the abstract
+origin attribute is a reference to the associated abstract instance entry.
+.P
+For each pair of entries that are associated via a
+.Cf DW_AT_abstract_origin
+attribute, both members of the pair will have the same tag.  So, for
+example, an entry with the tag 
+.Cf DW_TAG_local_variable 
+can only be associated
+with another entry that also has the tag 
+.Cf DW_TAG_local_variable.
+The only exception to this rule is that the root of a concrete
+instance tree (which must always have the tag 
+.Cf DW_TAG_inlined_subroutine )
+can only be associated with the root of its associated abstract
+instance tree (which must have the tag
+.Cf DW_TAG_subprogram ).
+.P
+In general, the structure and content of any given concrete
+instance tree will be directly analogous to the structure and content
+of its associated abstract instance tree.
+There are two exceptions to this general rule however.
+.AL
+.LI
+.IX anonymous types
+No entries representing anonymous types are ever made a part
+of any concrete instance inlined tree.
+.LI
+.IX members
+No entries representing members of structure, union or class
+types are ever made a part of any concrete inlined instance tree.
+.LE
+.P
+.I
+Entries that represent members and anonymous types are omitted from concrete
+inlined instance trees because they would simply be redundant duplicates of
+the corresponding entries in the associated abstract instance trees.  If
+any entry within a concrete inlined instance tree needs to refer to an
+anonymous type that was declared within the scope of the
+relevant inline function, the reference should simply refer to the abstract
+instance entry for the given anonymous type.
+.R
+.P
+.IX declarations, coordinates
+If an entry within a concrete inlined instance tree contains
+attributes describing the declaration coordinates of
+that entry,
+then those attributes should refer to the file, line and column
+of the original declaration of the subroutine, not to the
+point at which it was inlined.
+.H 4 "Out-of-Line Instances of Inline Subroutines"
+.IX subroutines, out-of-line
+Under some conditions, compilers may need to generate concrete executable
+instances of inline subroutines other than at points where those subroutines
+are actually called.  For the remainder of this discussion,
+such concrete instances of inline subroutines will
+be referred to as ``concrete out-of-line instances.'' 
+.P
+.I
+In C++, for example, taking the address of a function declared to be inline
+can necessitate the generation of a concrete out-of-line
+instance of the given function.
+.P
+.R
+The DWARF representation of a concrete out-of-line instance of an inline
+subroutine is essentially the same as for a concrete inlined instance of
+that subroutine (as described in the preceding section).  The representation
+of such a concrete out-of-line instance makes use of 
+.Cf DW_AT_abstract_origin
+attributes in exactly the same way as they are used for a concrete inlined
+instance (that is, as references to corresponding entries 
+within the associated
+abstract instance tree) and, as for concrete instance trees, the
+entries for anonymous types and for all members are omitted.
+.P
+The differences between the DWARF representation of a concrete out-of-line
+instance of a given subroutine and the representation of a concrete inlined
+instance of that same subroutine are as follows:
+.AL
+.LI
+The root entry for a concrete out-of-line instance of a given
+inline subroutine has the same tag as does its associated
+(abstract) inline subroutine entry (that is, it does not have the
+tag 
+.Cf DW_TAG_inlined_subroutine ).
+.LI
+The root entry for a concrete out-of-line instance tree is
+always directly owned by the same parent entry that
+also owns the root entry of the associated abstract instance.
+.LE
+.H 2   "Lexical Block Entries"

+A lexical block is a bracketed sequence of source statements that may
+contain any number of declarations.  In some languages (C and C++)
+blocks can be nested within other blocks to any depth.  
+.P
+.R
+A lexical block is represented by a debugging information entry
+with the tag
+.Cf DW_TAG_lexical_block .
+.P
+The lexical block entry has a 
+.Cf DW_AT_low_pc
+attribute whose value is the
+relocated address of the first machine instruction generated for the lexical
+block.
+The lexical block entry also has a 
+.Cf DW_AT_high_pc
+attribute whose value is the
+relocated address of the first location
+past the last machine instruction generated for the lexical block.
+.P
+If a name has been given to the lexical block in the source program,
+then the corresponding lexical block entry has a 
+.Cf DW_AT_name 
+attribute
+whose value is a null-terminated string containing the name of the
+lexical block as it appears in the source program.  
+.P
+.I
+This is not the
+same as a C or C++ label (see below).
+.R
+.P
+The lexical block entry owns debugging information entries that
+describe the declarations within that lexical block.
+There is one such debugging information entry for each local declaration
+of an identifier or inner lexical block.
+.H 2   "Label Entries"
+.I
+.IX labels
+A label is a way of identifying a source statement.  A labeled statement
+is usually the target of one or more ``go to'' statements.
+.P
+.R
+A label is represented by a debugging information entry
+with the tag 
+.Cf DW_TAG_label .
+The entry for a label should be owned by
+the debugging information entry representing the scope within which the name
+of the label could be legally referenced within the source program.
+.P
+The label entry has a 
+.Cf DW_AT_low_pc
+attribute whose value is the
+relocated address of the first machine instruction generated for the
+statement identified by the label in the source program.
+The label entry also has a

+.H 2 "With Statement Entries"
+.I
+.IX with statements
+.IX Pascal
+.IX Modula2
+Both Pascal and Modula support the concept of a ``with'' statement.

+.P
+.R
+A with statement is represented by a debugging information entry with
+the tag
+.Cf DW_TAG_with_stmt .
+A with statement entry has a 
+.Cf DW_AT_low_pc
+attribute whose value is the relocated
+address of the first machine instruction generated for the body of
+the with statement.  A with statement entry also has a 
+.Cf DW_AT_high_pc
+attribute whose value is the relocated
+address of the first location after the last machine instruction generated for the body of
+the statement.
+.P
+The with statement entry has a 
+.Cf DW_AT_type
+attribute, denoting
+the type of record whose fields may be referenced without full qualification
+within the body of the statement.  It also has a

+.IX catch blocks
+In C++ a lexical block may be designated as a ``catch block.''
+A catch block is an exception handler that handles exceptions

+designates the type of the exception that it can handle.
+.R
+.P
+A try block is represented by a debugging information entry
+with the tag

+A catch block is represented by a debugging information entry

+Each such entry is a child of the enumeration type entry, and
+the enumerator entries appear in the same order as the declarations of
+the enumeration literals in the source program.
+.P
+Each enumerator entry has a 
+.Cf DW_AT_name 
+attribute, whose value is
+a null-terminated string containing the name of the enumeration
+literal as it appears in the source program.  Each enumerator
+entry also has a
+.Cf DW_AT_const_value
+attribute, whose value is the actual numeric value of the enumerator
+as represented on the target system.
+.H 2     "Subroutine Type Entries"
+.I
+.IX subroutines, types
+It is possible in C to declare pointers to subroutines that return a value
+of a specific type.  In both ANSI C and C++, it is possible to declare
+pointers to subroutines that not only return a value of a specific type,
+but accept only arguments of specific types.  The type of such pointers
+would be described with a ``pointer to'' modifier applied to a user-defined
+type.  
+.R
+.P
+A subroutine type is represented by a debugging information entry
+with the tag
+.Cf DW_TAG_subroutine_type .
+If a name has been given to the subroutine type in the source program,
+then the corresponding subroutine type entry has a 
+.Cf DW_AT_name 
+attribute
+whose value is a null-terminated string containing the subroutine type
+name as it appears in the source program.
+.P
+.IX subroutines, return types
+If the subroutine type describes a function that returns a value, then
+the subroutine type entry has a 
+.Cf DW_AT_type
+attribute
+to denote the type returned by the subroutine.
+If the types of the arguments are necessary to describe the subroutine type,
+then the corresponding subroutine type entry owns debugging
+information entries that describe the arguments.
+These debugging information entries appear in the order
+that the corresponding argument types appear in the source program.
+.P
+.I
+.IX C %c
+.IX subroutines, prototypes
+In ANSI-C there is a difference between the types of functions
+declared using function prototype style declarations and those
+declared using non-prototype declarations.  
+.P
+.R
+A subroutine entry
+declared with a function prototype style declaration may have a
+.Cf DW_AT_prototyped
+attribute, whose value is a flag.
+.P
+Each debugging information entry
+owned by a subroutine type entry has a tag whose value has one of
+two possible interpretations.  
+.AL
+.LI
+.IX parameters, formal
+Each debugging information entry that is owned by a subroutine type entry and
+that defines a single argument of a specific type has the tag
+.Cf DW_TAG_formal_parameter .
+.P
+The formal parameter entry has a type attribute
+to denote the type of the corresponding formal parameter.
+.LI
+The unspecified parameters of a variable parameter list are represented by a
+debugging information entry owned by the subroutine type entry with the tag
+.Cf DW_TAG_unspecified_parameters .
+.IX parameters, unspecified
+.LE
+.H 2     "String Type Entries"
+.I
+.IX string types
+.IX Fortran
+A ``string'' is a sequence of characters that have specific semantics and
+operations that separate them from arrays of characters.  
+Fortran is one of
+the languages that has a string type.
+.R
+.P
+A string type is represented by a debugging information entry
+with the tag 
+.Cf DW_TAG_string_type .
+If a name has been given to the string type in the source program,
+then the corresponding string type entry has a 
+.Cf DW_AT_name 
+attribute
+whose value is a null-terminated string containing the string type
+name as it appears in the source program.
+.P
+The string type entry may have a
+.Cf DW_AT_string_length
+attribute whose value is a location description
+yielding the location where the length of the string
+is stored in the program.  The string type entry may also have a
+.Cf DW_AT_byte_size 
+attribute, whose constant value is the size in bytes of the data
+to be retrieved from the location referenced by the string length
+attribute.  If no byte size attribute is present, the size of the
+data to be retrieved is the same as the size of an address on
+the target machine.
+.P
+If no string length attribute is present, the string type entry may have
+a 
+.Cf DW_AT_byte_size 
+attribute, whose constant value is the length in bytes of
+the string.
+.H 2 "Set Entries"
+.I
+Pascal provides the concept of a ``set,'' which represents a group of
+values of ordinal type.
+.P
+.R
+.IX Pascal
+.IX set types
+A set is represented by a debugging information entry
+with the tag
+.Cf DW_TAG_set_type .
+If a name has been given to the set type,
+then the set type entry has a 
+.Cf DW_AT_name 
+attribute
+whose value is a null-terminated string containing the set type name
+as it appears in the source program.
+.P
+The set type entry has a 
+.Cf DW_AT_type
+attribute to denote the type 
+of an element of the set.  
+.P
+If the amount of storage allocated to hold each element of an object of
+the given set type is different from the amount of storage that is normally
+allocated to hold an individual object of the indicated element type, then
+the set type entry has a 
+.Cf DW_AT_byte_size 
+attribute, whose constant value
+represents the size in bytes of an instance of the set type.
+.H 2 "Subrange Type Entries"
+.I
+Several languages support the concept of a ``subrange'' type object.
+These objects can represent a subset of the values that an
+object of the basis type for the subrange can represent.
+Subrange type entries may also be used to represent the bounds
+of array dimensions.
+.R
+.P
+.IX subranges
+A subrange type is represented by a debugging information entry
+with the tag
+.Cf DW_TAG_subrange_type .
+If a name has been given to the subrange type,
+then the subrange type entry has a 
+.Cf DW_AT_name 
+attribute
+whose value is a null-terminated string containing the subrange type name
+as it appears in the source program.
+.P
+The subrange entry may have a 
+.Cf DW_AT_type
+attribute to describe
+the type of object of whose values this subrange is a subset.
+.P
+If the amount of storage allocated to hold each element of an object of
+the given subrange type is different from the amount of storage that is normally
+allocated to hold an individual object of the indicated element type, then
+the subrange type entry has a
+.Cf DW_AT_byte_size 
+attribute, whose constant value
+represents the size in bytes of each element of the subrange type.
+.P
+The subrange entry may have the attributes
+.Cf DW_AT_lower_bound
+and
+.Cf DW_AT_upper_bound
+to describe, respectively, the lower and upper bound values
+of the subrange.
+The 
+.Cf DW_AT_upper_bound
+attribute may be replaced by a
+.Cf DW_AT_count
+attribute, whose value describes the number of elements in
+the subrange rather than the value of the last element.
+If a bound or count value is described by a constant
+not represented in the program's address space and can
+be represented by one of the constant attribute forms, then the value
+of the lower or upper bound or count attribute may be one of the constant
+types.  Otherwise, the value of the lower or upper bound or count
+attribute is a reference to a debugging information entry describing
+an object containing the bound value or itself describing a constant
+value. 
+.P
+If either the lower or upper bound or count values are missing, the
+bound value is assumed to be a language-dependent default
+constant.
+.P
+.I
+.IX C %c
+.IX C++ %caa
+.IX Fortran
+The default lower bound value for C or C++ is 0.  For Fortran,
+it is 1.  No other default values are currently defined by DWARF.
+.R
+.P
+If the subrange entry has no type attribute describing the basis
+type, the basis type is assumed to be the same as the object
+described by the lower bound attribute (if it references an object).
+If there is no lower bound attribute, or it does not reference
+an object, the basis type is the type of the upper bound or count
+attribute
+(if it references an object).  If there is no upper bound or count attribute
+or it does not reference an object, the type is assumed to be
+the same type, in the source language
+of the compilation unit containing the subrange entry,
+as a signed integer with the same size
+as an address on the target machine.
+.H 2 "Pointer to Member Type Entries"
+.I
+In C++, a pointer to a data or function member of a class or
+structure is a unique type.  
+.P
+.R
+.IX C++ %caa
+.IX members, pointers to
+.IX pointers to members
+A debugging information entry
+representing the type of an object that is a pointer to a structure
+or class member has the tag
+.Cf DW_TAG_ptr_to_member_type .
+.P
+If the pointer to member type has a name, the pointer to member entry
+has a 
+.Cf DW_AT_name 
+attribute, whose value is a null-terminated string
+containing the type name as it appears in the source program.
+.P
+The pointer to member entry has a
+.Cf DW_AT_type
+attribute to describe
+the type of the class or structure member to which objects
+of this type may point.
+.P
+The pointer to member entry also has a
+.Cf DW_AT_containing_type
+attribute, whose value is a reference to a debugging information
+entry for the class or structure to whose members objects of
+this type may point.
+.P
+Finally, the pointer to member entry has a
+.Cf DW_AT_use_location
+attribute whose value is a location description that computes
+the address of the member of the class or structure to which the
+pointer to member type entry can point.
+.P
+.I
+The method used to find the address of a given member
+of a class or structure is common to any instance of that
+class or structure and to any instance of the pointer or
+member type.  The method is thus associated
+with the type entry, rather than with each instance of the type.
+.P
+The 
+.Cf DW_AT_use_location
+expression, however, cannot be used on its own, but must
+be used in conjunction with the location expressions for
+a particular object of the given pointer to member type
+and for a particular structure or class instance.  The 
+.Cf DW_AT_use_location
+attribute expects two values to be pushed onto the location expression
+stack before the
+.Cf DW_AT_use_location
+expression is evaluated.  The first value pushed should be
+the value of the pointer to member object itself.
+The second value pushed should be the base address of the entire
+structure or union instance containing the member whose
+address is being calculated.
+.P
+So, for an expression like
+.DS
+	\f(CWobject.*mbr_ptr\fP
+.DE
+where \f(CWmbr_ptr\fP has some pointer to member type,
+a debugger should:
+.AL
+.LI
+Push the value of 
+.Cf mbr_ptr
+onto the location expression stack.
+.LI
+Push the base address of
+.Cf object 
+onto the location expression stack.
+.LI
+Evaluate the 
+.Cf DW_AT_use_location
+expression for the type of 
+.Cf mbr_ptr .
+.LE
+.R
+.H 2 "File Type Entries"
+.I
+Some languages, such as Pascal, provide a first class data type
+to represent files.
+.R
+.P
+.IX Pascal
+.IX file types
+A file type is represented by a debugging information entry
+with the tag
+.Cf DW_TAG_file_type.
+If the file type has a name, the file type entry
+has a 
+.Cf DW_AT_name 
+attribute, whose value is a null-terminated string
+containing the type name as it appears in the source program.
+.P
+The file type entry has a 
+.Cf DW_AT_type
+attribute describing the type
+of the objects contained in the file.
+.P
+The file type entry also has a 
+.Cf DW_AT_byte_size 
+attribute, whose value
+is a constant representing the size in bytes of an instance
+of this file type. 
+.OP
+.H 1 "OTHER DEBUGGING INFORMATION"
+This section describes debugging information that
+is not represented in the form of debugging information
+entries and is not contained within the 
+.Cf .debug_info
+section.
+.H 2 "Accelerated Access"
+.I
+.IX accelerated access
+A debugger frequently needs to find the debugging information for
+a program object defined outside of the compilation unit
+where the debugged program is currently stopped.  Sometimes
+it will know only the name of the object; sometimes only the address.
+To find the debugging information
+associated with a global object by name, using the DWARF debugging information
+entries alone, a debugger would need
+to run through all entries at the highest scope within each
+compilation unit.  For lookup by address, for a subroutine,
+a debugger can use the low and high pc attributes
+of the compilation unit entries to quickly narrow down the search,
+but these attributes only cover 
+the range of addresses for the text associated with a compilation
+unit entry.  To find the debugging information associated with a
+data object, an exhaustive search would be needed.
+Furthermore, any search through debugging information entries for
+different compilation units within a large program
+would potentially require the access of many memory pages,
+probably hurting debugger performance.
+.R
+.P
+To make lookups of program objects by name or by address faster,
+a producer of DWARF information may provide two different types
+of tables containing information about the debugging information
+entries owned by a particular compilation unit entry in a more condensed
+format.
+.H 3 "Lookup by Name"
+.IX lookup, by name
+For lookup by name, a table is maintained in a separate
+object file section called
+.Cf .debug_pubnames .
+.IX \f(CW.debug_pubnames\fP %debugap
+The table consists of sets of variable length entries, each
+set describing the names of global objects whose definitions
+or declarations are represented by debugging information entries
+owned by a single compilation unit.  Each set begins
+with a header containing four values: the total length of the entries
+for that set, not including the length field itself, a version number,
+the offset from the beginning of the
+.Cf .debug_info
+.IX \f(CW.debug_info\fP %debugai
+section of the compilation unit entry referenced by the set and
+the size in bytes of the contents of the
+.Cf .debug_info
+section generated to represent that compilation unit. This
+header is followed by a variable number of offset/name pairs.
+Each pair consists of the offset from the beginning of the compilation
+unit entry corresponding to the current set to the 
+debugging information entry for
+the given object, followed by a null-terminated character
+string representing the name of the object as given by
+the
+.Cf DW_AT_name
+attribute of the referenced debugging entry.
+Each set of names is terminated by zero.
+.P
+.IX C++ %caa
+.IX members, static data
+In the case of the name of a static data member or function member
+of a C++ structure, class or union, the name presented
+in the 
+.Cf .debug_pubnames
+section is not the simple name given by the
+.Cf DW_AT_name 
+attribute of the referenced debugging entry, but rather
+the fully class qualified name of the data or function member.
+.IX identifiers, names
+.H 3 "Lookup by Address"
+.IX lookup, by address
+For lookup by address, a table is maintained in a separate
+object file section called
+.Cf .debug_aranges .
+.IX \f(CW.debug_aranges\fP %debugaar
+The table consists of sets of variable length entries, each
+set describing the portion of the program's address space that
+is covered by a single compilation unit.  Each set begins
+with a header containing five values: 
+.AL
+.LI
+The total length of the entries
+for that set, not including the length field itself.
+.LI
+A version number.
+.LI
+The offset from the beginning of the
+.Cf .debug_info
+.IX \f(CW.debug_info\fP %debugai
+section of the compilation unit entry referenced by the set. 
+.LI
+The size in bytes of an address on the target architecture.  For
+segmented addressing, this is the size of the offset portion of the
+.IX addresses, offset portion
+.IX addresses, size of
+address.
+.LI
+.IX address space, segmented
+.IX segmented address space
+The size in bytes of a segment descriptor on the target architecture.
+If the target system uses a flat address space, this value is 0.
+.LE
+.P
+This
+header is followed by a variable number of address
+range descriptors.  Each descriptor is a pair consisting of 
+the beginning address
+of a range of text or data covered by some entry owned
+by the corresponding compilation unit entry, followed by the length
+of that range.  A particular set is terminated by an entry consisting
+of two zeroes.  By scanning the table, a debugger can quickly
+decide which compilation unit to look in to find the debugging information
+for an object that has a given address.
+.H 2 "Line Number Information"
+.I
+.IX line number information
+A source-level debugger will need to know how to associate statements in
+the source files with the corresponding machine instruction addresses in
+the executable object or the shared objects used by that executable
+object.  Such an association would make it possible for the debugger user
+to specify machine instruction addresses in terms of source statements.
+This would be done by specifying the line number and the source file
+containing the statement.  The debugger can also use this information to
+display locations in terms of the source files and to single step from
+statement to statement.
+.R
+.P
+As mentioned in section 3.1, above, 
+the line number information generated for a compilation unit
+is represented in the \f(CW.debug_line\fP section of an object file and is
+referenced by a corresponding compilation unit debugging information entry
+in the \f(CW.debug_info\fP section.
+.IX \f(CW.debug_info\fP %debugai
+.IX \f(CW.debug_line\fP %debugali
+.I
+.P
+If space were not a consideration, the information
+provided in the 
+.Cf .debug_line
+section could be represented as a large matrix,
+with one row for each instruction in the emitted
+object code.  The matrix would have columns for:
+.DL
+.LI
+the source file name
+.LI
+the source line number
+.LI
+the source column number
+.LI
+whether this instruction is the beginning of a source statement
+.LI
+whether this instruction is the beginning of a basic block.
+.LE
+.P
+Such a matrix, however, would be impractically large.  We shrink it with
+two techniques.  First, we delete from the matrix each row whose file,
+line and source column information is identical with that of its predecessors.
+Second, we design a byte-coded language for a state machine and store a stream
+of bytes in the object file instead of the matrix.  This language can be
+much more compact than the matrix.  When a consumer of the statement
+information executes, it must ``run'' the state machine to generate
+the matrix for each compilation unit it is interested in.  The concept
+of an encoded matrix also leaves room for expansion.  In the future,
+columns can be added to the matrix to encode other things that are
+related to individual instruction addresses.
+.R
+.H 3 "Definitions"
+.IX line number information, definitions
+The following terms are used in the description of the line number information
+format:
+.VL 20
+.LI "state machine"
+The hypothetical machine used by a consumer of the line number information 
+to expand the byte-coded instruction stream into a 
+matrix of line number information.
+.LI "statement program"
+A series of byte-coded line number information instructions representing one
+compilation unit.
+.LI "basic block"
+A sequence of instructions that is entered only at the first instruction
+and exited only at the last instruction.  We define a procedure invocation
+to be an exit from a basic block.
+.LI "sequence"
+A series of contiguous target machine instructions.  One compilation
+unit may emit multiple sequences (that is, not all instructions within
+a compilation unit are assumed to be contiguous).
+.LI "sbyte"
+Small signed integer.
+.LI "ubyte"
+Small unsigned integer.
+.LI "uhalf"
+Medium unsigned integer.
+.LI "sword"
+Large signed integer.
+.LI "uword"
+Large unsigned integer.
+.LI "LEB128"
+.IX LEB128
+Variable length signed and unsigned data.  See section 7.6.
+.LE
+.H 3 "State Machine Registers"
+.IX line number information, state machine registers
+The statement information state machine has the following registers:
+.VL 20
+.LI "\f(CWaddress\fP"
+The program-counter value corresponding to a machine instruction generated
+by the compiler.
+.LI "\f(CWfile\fP"
+An unsigned integer indicating the identity of the source file corresponding
+to a machine instruction.
+.IX source, files
+.LI "\f(CWline\fP"
+.IX source, lines
+An unsigned integer indicating a source line number.  Lines are numbered
+beginning at 1.  The compiler may emit the value 0 in cases where an
+instruction cannot be attributed to any source line.
+.LI "\f(CWcolumn\fP"
+.IX source, columns
+An unsigned integer indicating a column number within a source line.
+Columns are numbered beginning at 1.  The value 0 is reserved to indicate
+that a statement begins at the ``left edge'' of the line.
+.LI "\f(CWis_stmt\fP"
+A boolean indicating that the current instruction is the beginning of a
+statement.
+.LI "\f(CWbasic_block\fP"
+A boolean indicating that the current instruction is the beginning of
+a basic block.
+.LI "\f(CWend_sequence\fP"
+A boolean indicating that the current address is that of the first
+byte after the end of a sequence of target machine instructions.
+.LE
+.P
+At the beginning of each sequence within a statement program, the
+state of the registers is:

+.DE
+.H 3 "Statement Program Instructions"
+The state machine instructions in a statement program belong to one
+of three categories:
+.VL 20
+.LI "special opcodes"
+.IX line number information, special opcodes
+These have a ubyte opcode field and no arguments. 
+Most of the instructions in a statement program are special opcodes.
+.LI "standard opcodes"
+.IX line number information, standard opcodes
+These have a ubyte opcode field which may be followed by zero or more
+LEB128 arguments (except for 
+.Cf DW_LNS_fixed_advance_pc ,
+see below).
+The opcode implies the number of arguments and their 
+meanings, but the statement program prologue also specifies the number 
+of arguments for each standard opcode.
+.LI "extended opcodes"
+.IX line number information, extended opcodes
+These have a multiple byte format.  The first byte is zero;
+the next bytes are an unsigned LEB128 integer giving the number of bytes
+in the instruction itself (does not include the first zero byte or the size).
+The remaining bytes are the instruction itself.
+.LE
+.H 3 "The Statement Program Prologue"
+.IX line number information, prologue
+The optimal encoding of line number information depends to a certain
+degree upon the architecture of the target machine.  The statement program
+prologue provides information used by consumers in decoding the statement
+program instructions for a particular compilation unit and also provides
+information used throughout the rest of the statement program.  The statement
+program for each compilation unit begins with a prologue containing the
+following fields in order:
+.AL
+.LI
+.Cf total_length 
+(uword)
+.br
+The size in bytes of the statement information for this compilation unit
+(not including the 
+.Cf total_length
+field itself).
+.LI
+.Cf version
+(uhalf)
+.br
+Version identifier for the statement information format.
+.LI
+.Cf prologue_length 
+(uword)
+.br
+The number of bytes following the 
+.Cf prologue_length
+field to the beginning of the first byte of the statement program itself.
+.LI
+.Cf minimum_instruction_length
+(ubyte)
+.br
+The size in bytes of the smallest target machine instruction.  Statement
+program opcodes that alter the 
+.Cf address 
+register first multiply their operands by this value.
+.LI
+.Cf default_is_stmt
+(ubyte)
+.br
+The initial value of the 
+.Cf is_stmt
+register.  
+.P
+.I
+A simple code generator
+that emits machine instructions in the order implied by the source program
+would set this to ``true,'' and every entry in the matrix would represent
+a statement boundary.  A pipeline scheduling code generator would set
+this to ``false'' and emit a specific statement program opcode for each
+instruction that represented a statement boundary.
+.R
+.LI
+.Cf line_base 
+(sbyte)
+.br
+This parameter affects the meaning of the special opcodes.  See below.
+.LI
+.Cf line_range 
+(ubyte)
+.br
+This parameter affects the meaning of the special opcodes.  See below.
+.LI
+.Cf opcode_base
+(ubyte)
+.br
+The number assigned to the first special opcode.
+.LI
+.Cf standard_opcode_lengths
+(array of ubyte)
+.br
+This array specifies the number of LEB128 operands for each of
+the standard opcodes.  The first element of the array corresponds
+to the opcode whose value is 1, and the last element corresponds
+to the opcode whose value is 
+.Cf "opcode_base - 1" . 
+By increasing
+.Cf opcode_base , 
+and adding elements to this array, new standard opcodes
+can be added, while allowing consumers who do not know about these
+new opcodes to be able to skip them.
+.LI
+.Cf include_directories
+(sequence of path names)
+.br
+The sequence contains an entry for each path that was searched
+for included source files in this compilation.  (The paths include
+those directories specified explicitly by the user for the compiler
+to search and those the compiler searches without explicit direction).
+Each path entry is either a full
+path name or is relative to the current directory of the compilation.
+The current directory of the compilation is understood to be the first entry
+and is not explicitly represented.  
+Each entry is a null-terminated
+string containing a full path name.  The last entry is followed by
+a single null byte.
+.LI
+.Cf file_names
+(sequence of file entries)
+.br
+.IX source, files
+The sequence contains an entry for each source file that contributed
+to the statement information for this compilation unit or is
+used in other contexts, such as in a declaration coordinate
+or a macro file inclusion.  Each entry
+has a null-terminated string containing the file name, 
+an unsigned LEB128 number representing the directory index of the
+directory in which the file was found, 
+an unsigned LEB128 number representing the time of last modification for
+the file and an unsigned LEB128 number representing the length in
+bytes of the file.  A compiler may choose to emit LEB128(0) for the
+time and length fields to indicate that this information is not
+available.  The last entry is followed by a single null byte.
+.P
+The directory index represents an entry in the
+.Cf include_directories
+section.  The index is LEB128(0) if the file was found in
+the current directory of the compilation, LEB128(1) if it was
+found in the first directory in the
+.Cf include_directories
+section, and so on.  The directory index is ignored for file names
+that represent full path names.
+.P
+The statement program assigns numbers to each of the file entries
+in order, beginning with 1, and uses those numbers instead of file
+names in the 
+.Cf file 
+register.
+.P
+A compiler may generate a single null byte for the file names field
+and define file names using the extended opcode
+.Cf DEFINE_FILE .
+.LE
+.H 3 "The Statement Program"
+As stated before, the goal of a statement program is to build a 
+matrix representing
+one compilation unit, which may have produced multiple sequences of
+target-machine instructions. Within a sequence, addresses may only increase.
+(Line numbers may decrease in cases of pipeline scheduling.)
+.H 4 "Special Opcodes"
+.IX line number information, special opcodes
+Each 1-byte special opcode has the following effect on the state machine:
+.AL
+.LI
+Add a signed integer to the 
+.Cf line 
+register.
+.LI
+Multiply an unsigned integer by the 
+.Cf minimum_instruction_length
+field of the statement program prologue and

+Append a row to the matrix using the current values of the state machine
+registers.
+.LI
+Set the 
+.Cf basic_block 
+register to ``false.''
+.LE
+.P
+All of the special opcodes do those same four things; 
+they differ from one another
+only in what values they add to the 
+.Cf line 
+and 
+.Cf address 
+registers.
+.P
+.I
+Instead of assigning a fixed meaning to each special opcode, the statement
+program uses several
+parameters in the prologue to configure the instruction set. There are two
+reasons for this.
+First, although the opcode space available for special opcodes now
+ranges from 10 through 255, the lower bound may increase if one adds new
+standard opcodes. Thus, the 
+.Cf opcode_base
+field of the statement program
+prologue gives the value of the first special opcode.
+Second, the best choice of special-opcode meanings depends on the target
+architecture.  For example, for a RISC machine where the compiler-generated code
+interleaves instructions from different lines to schedule the pipeline,
+it is important to be able to add a negative value to the 
+.Cf line 
+register
+to express the fact that a later instruction may have been emitted for an
+earlier source line.  For a machine where pipeline scheduling never occurs,
+it is advantageous to trade away the ability to decrease the 
+.Cf line 
+register
+(a standard opcode provides an alternate way to decrease the line number) in
+return for the ability to add larger positive values to the 
+.Cf address
+register.  To permit this variety of strategies, the statement program prologue 
+defines a 
+.Cf line_base
+field that specifies the minimum value which a special opcode can add
+to the 
+.Cf line
+register and a 
+.Cf line_range
+field that defines the range of
+values it can add to the 
+.Cf line 
+register.
+.R
+.P
+A special opcode value is chosen based on the amount that needs to
+be added to the 
+.Cf line
+and 
+.Cf address
+registers.  The maximum line increment
+for a special opcode is the value of the 
+.Cf line_base
+field in the
+prologue, plus the value of the 
+.Cf line_range 
+field, minus 1 
+(\f(CWline base + line range - 1\fP).  If the desired line increment
+is greater than the maximum line increment, a standard opcode
+must be used instead of a special opcode.
+The ``address advance'' is calculated by dividing the desired address
+increment by the 
+.Cf minimum_instruction_length
+field from the
+prologue.  The special opcode is then calculated using the following
+formula:
+.br
+        \f(CWopcode = (desired line increment - line_base) +
+.br
+                (line_range * address advance) + opcode_base\fP
+.br
+If the resulting opcode is greater than 255, a standard opcode
+must be used instead.
+.P
+To decode a special opcode, subtract the 
+.Cf opcode_base
+from
+the opcode itself.  The amount to increment the 
+.Cf address 
+register is
+the adjusted opcode divided by the 
+.Cf line_range .
+The amount to
+increment the 
+.Cf line 
+register is the 
+.Cf line_base
+plus the result
+of the adjusted opcode modulo the 
+.Cf line_range .
+That is,
+.br
+	\f(CWline increment = line_base + (adjusted opcode % line_range)\fP
+.br
+.P
+.I
+As an example, suppose that the 
+.Cf opcode_base 
+is 16, 
+.Cf line_base
+is -1 and 
+.Cf line_range
+is 4.
+This means that we can use a special opcode whenever two successive
+rows in the matrix have source line numbers differing by any value within
+the range [-1, 2] (and, because of the limited number of opcodes available,
+when the difference between addresses is within the range [0, 59]).
+.P
+The opcode mapping would be:
+.R
+.DS
+.TS
+box center;
+l l l
+nf(CW) nf(CW) nf(CW)

+.H 4 "Standard Opcodes"
+.IX line number information, standard opcodes
+There are currently 9 standard ubyte opcodes.  In the future 
+additional ubyte opcodes may be defined by setting the 
+.Cf opcode_base
+field in the statement program
+prologue to a value greater than 10.
+.AL
+.LI

+.LI
+.Cf DW_LNS_advance_pc
+.br
+Takes a single unsigned LEB128 operand,
+multiplies it by the
+.Cf minimum_instruction_length
+field of the prologue, and adds the result to the
+.Cf address
+register of the state machine.
+.LI
+.Cf DW_LNS_advance_line
+.br
+Takes a single signed LEB128 operand and adds
+that value to the 
+.Cf line
+register of the state machine.

+.br
+Takes a single unsigned LEB128 operand and stores
+it in the

+.br
+Takes a single unsigned LEB128 operand and stores
+it in the

+.br
+Takes no arguments.
+Set the

+.br
+Takes no arguments.  Set the 
+.Cf basic_block 
+register of the state machine to ``true.''

+.Cf DW_LNS_const_add_pc
+.br
+Takes no arguments.
+Add to the 
+.Cf address 
+register of the state machine the
+address increment value corresponding to special
+opcode 255.
+.P
+.I
+The motivation for 
+.Cf DW_LNS_const_add_pc 
+is this:  when the statement program needs
+to advance the address by a small amount, it can use a single special
+opcode, which occupies a single byte.  When it needs to advance the
+address by up to twice the range of the last special opcode, it can use
+.Cf DW_LNS_const_add_pc 
+followed by a special opcode, for a total of two bytes.
+Only if it needs to advance the address by more than twice that range
+will it need to use both
+.Cf DW_LNS_advance_pc
+and a special opcode, requiring three or more bytes.
+.R
+.LI
+.Cf DW_LNS_fixed_advance_pc
+.br
+Takes a single uhalf operand.  Add to the 
+.Cf address 
+register of the state machine the value of the (unencoded) operand.
+This is the only extended opcode that takes an argument that is not
+a variable length number.
+.P
+.I
+The motivation for 
+.Cf DW_LNS_fixed_advance_pc
+is this:  existing assemblers cannot emit 
+.Cf DW_LNS_advance_pc
+or special opcodes because they cannot encode LEB128 numbers
+or judge when the computation of a special opcode overflows and requires
+the use of 
+.Cf DW_LNS_advance_pc .
+Such assemblers, however,  can use
+.Cf DW_LNS_fixed_advance_pc
+instead, sacrificing compression. 
+.R
+.LE
+.H 4 "Extended Opcodes"
+.IX line number information, extended opcodes
+There are three extended opcodes currently defined.  The first byte

+\f(CWDW_LNE_end_sequence\fP 
+.br

+reset the registers to the initial values specified
+above.
+.P
+Every statement program sequence must end with a
+.Cf DW_LNE_end_sequence
+instruction which creates a
+row whose address is that of the byte after the last target machine instruction
+of the sequence.
+.LI
+\f(CWDW_LNE_set_address\fP
+.br
+Takes a single relocatable address as an operand.  The size of the
+operand is the size appropriate to hold an address on the target machine.
+Set the

+register to the value given by the
+relocatable address. 
+.P
+.I
+All of the other statement program opcodes that affect the

+.LI
+\f(CWDW_LNE_define_file\fP
+.br
+.IX source, files
+Takes 4 arguments.  The first is a null terminated string containing a
+source file name.  The second is an
+unsigned LEB128 number representing the directory index of the
+directory in which the file was found.
+The third is an unsigned LEB128 number representing
+the time of last modification of the file.  The fourth is an unsigned
+LEB128 number representing the length in bytes of the file.
+The time and length fields may contain LEB128(0) if the information is
+not available.
+.P
+The directory index represents an entry in the
+.Cf include_directories
+section of the statement program prologue.  
+The index is LEB128(0) if the file was found in
+the current directory of the compilation, LEB128(1) if it was
+found in the first directory in the
+.Cf include_directories
+section, and so on.  The directory index is ignored for file names
+that represent full path names.
+.P
+The files are numbered, starting at 1,
+in the order in which they appear; the names in the prologue
+come before names defined by the
+.Cf DW_LNE_define_file
+instruction.
+These numbers are used in the the 
+.Cf file 
+register of the state machine.

+.R
+.H 2 "Macro Information"
+.I
+.IX macro information
+.IX pre-processor
+.IX C %c
+.IX C++ %caa
+Some languages, such as C and C++, provide a way to replace text
+in the source program with macros defined either in the source
+file itself, or in another file included by the source file.
+Because these macros are not themselves defined in the target
+language, it is difficult to represent their definitions
+using the standard language constructs of DWARF.  The debugging
+information therefore reflects the state of the source after
+the macro definition has been expanded, rather than as the
+programmer wrote it.
+The macro information table provides a way of preserving the original
+source in the debugging information.
+.R
+.P
+As described in section 3.1, the macro information for a given
+compilation unit is represented in the
+.Cf .debug_macinfo
+.IX \f(CW.debug_macinfo\fP %debugam
+section of an object file.  The macro information for each compilation
+unit is represented as a series of ``macinfo'' entries.  Each
+macinfo entry consists of a ``type code'' and up to two additional
+operands.  The series of entries for a given compilation unit
+ends with an entry containing a type code of 0.
+.H 3 "Macinfo Types"
+The valid macinfo types are as follows:
+.VL 30
+.LI \f(CWDW_MACINFO_define\fP
+A macro definition.
+.LI \f(CWDW_MACINFO_undef\fP
+A macro un-definition.
+.LI \f(CWDW_MACINFO_start_file\fP
+The start of a new source file inclusion.
+.LI \f(CWDW_MACINFO_end_file\fP
+The end of the current source file inclusion.
+.LI \f(CWDW_MACINFO_vendor_ext\fP
+Vendor specific macro information directives that do not fit
+into one of the standard categories.
+.LE
+.H 4 "Define and Undefine Entries"
+.IX macro information, define and undefine entries
+All 
+.Cf DW_MACINFO_define
+and 
+.Cf DW_MACINFO_undef
+entries have two operands.
+The first operand encodes the line number of the source line
+.IX source, lines
+on which the relevant defining or undefining
+pre-processor directives appeared.
+.P 
+The second operand consists of a null-terminated character string.
+In the case of a 
+.Cf DW_MACINFO_undef 
+entry, the value of this
+string will be simply the name of the pre-processor
+symbol which was undefined at the indicated source line.
+.P
+In the case of a 
+.Cf DW_MACINFO_define
+entry, the value of this
+string will be the name of the pre-processor symbol
+that was defined at the indicated source line,
+followed immediately by the macro formal parameter
+list including the surrounding parentheses (in the
+case of a function-like macro) followed by the
+definition string for the macro.  If there is no
+formal parameter list, then the name of the defined
+macro is followed directly by its definition string.
+.P
+In the case of a function-like macro definition, no
+whitespace characters should appear between the
+name of the defined macro and the following left
+parenthesis.  Also, no whitespace characters should
+appear between successive formal parameters in the
+formal parameter list.  (Successive formal parameters
+should, however, be separated by commas.)  Also, exactly
+one space character
+should separate the right parenthesis which terminates
+the formal parameter list and the following definition
+string.
+.P
+In the case of a ``normal'' (i.e. non-function-like)
+macro definition, exactly one space character
+should separate the name of the defined macro from the following definition
+text.
+.H 4 "Start File Entries"
+.IX macro information, start file entries
+Each 
+.Cf DW_MACINFO_start_file
+entry also has two operands.  The first operand
+encodes the line number of the
+source line on which the inclusion pre-processor
+directive occurred.
+.P
+.IX source, files
+The second operand encodes a
+source file name index.  This index corresponds to a file
+number in the statement information table for the relevant
+compilation unit.  This index
+indicates (indirectly) the name of the file
+which is being included by the inclusion directive on
+the indicated source line.
+.H 4 "End File Entries"
+.IX macro information, end file entries
+A 
+.Cf DW_MACINFO_end_file 
+entry has no operands.  The presence of the entry marks the end of
+the current source file inclusion.
+.H 4 "Vendor Extension Entries"
+.IX macro information, vendor extensions
+.IX vendor extensions
+A
+.Cf DW_MACINFO_vendor_ext
+entry has two operands.
+The first is a constant.  The second is a null-terminated
+character string.
+The meaning and/or significance of these operands is
+intentionally left undefined by this specification.
+.P
+A consumer must be able to totally ignore all
+.Cf DW_MACINFO_vendor_ext
+entries that it does not understand.
+.H 3 "Base Source Entries"
+.IX macro information, base source entries
+In addition to producing a matched pair of
+.Cf DW_MACINFO_start_file 
+and 
+.Cf DW_MACINFO_end_file
+entries for 
+each inclusion directive actually processed during
+compilation, a producer should generate such a matched
+pair also for the ``base'' source file submitted to the
+compiler for compilation.  If the base source file
+.IX source, files
+for a compilation is submitted to the compiler via
+some means other than via a named disk file (e.g. via
+the standard input \fIstream\fP on a UNIX system) then the
+compiler should still produce this matched pair of
+.Cf DW_MACINFO_start_file
+and 
+.Cf DW_MACINFO_end_file 
+entries for
+the base source file, however, the file name indicated
+(indirectly) by the 
+.Cf DW_MACINFO_start_file
+entry of the
+pair should reference a statement information file name entry consisting
+of a null string.
+.H 3 "Macinfo Entries for Command Line Options"
+.IX macro information, command line options
+In addition to producing
+.Cf DW_MACINFO_define 
+and
+.Cf DW_MACINFO_undef
+entries for each of the define and
+undefine directives processed during compilation, the
+DWARF producer should generate a 
+.Cf DW_MACINFO_define 
+or
+.Cf DW_MACINFO_undef
+entry for each pre-processor symbol
+which is defined or undefined by some
+means other than via a define or undefine directive
+within the compiled source text.  In particular,
+pre-processor symbol definitions and un-definitions
+which occur as a result of command line options
+(when invoking the compiler) should be represented by
+their own 
+.Cf DW_MACINFO_define
+and 
+.Cf DW_MACINFO_undef
+entries.
+.P
+All such 
+.Cf DW_MACINFO_define
+and 
+.Cf DW_MACINFO_undef
+entries representing compilation options should appear 
+before the first 
+.Cf DW_MACINFO_start_file
+entry for that compilation unit and should encode the value
+0 in their line number operands.
+.H 3 " General Rules and Restrictions"
+.IX line number information, general rules
+All macinfo entries within a 
+.Cf .debug_macinfo 
+section for a given compilation unit should appear in the same order
+in which the directives were processed by the compiler.
+.P
+All macinfo entries representing command line options
+should appear in the same order as the relevant command
+line options were given to the compiler.  In the case
+where the compiler itself implicitly supplies one or
+more macro definitions or un-definitions in addition
+to those which may be specified on the command line,
+macinfo entries should also be produced for these
+implicit definitions and un-definitions, and
+these entries should also appear in the proper order
+relative to each other and to any definitions or
+undefinitions given explicitly by the user on the
+command line.
+.H 2 "Call Frame Information"
+.IX call frame information
+.IX activations
+.I
+Debuggers often need to be able to view and modify the state of any
+subroutine activation that is on the call stack.  An activation
+consists of:
+.BL
+.LI
+A code location that is within the subroutine.  This location is
+either the place where the program stopped when the debugger got
+control (e.g. a breakpoint), or is a place where a subroutine
+made a call or was interrupted by an asynchronous event (e.g. a
+signal).
+.LI
+An area of memory that is allocated on a stack called a ``call
+frame.''  The call frame is identified by an address on the
+stack.  We refer to this address as the Canonical Frame Address or CFA.
+.LI
+A set of registers that are in use by the subroutine at the code
+location.
+.LE
+.P
+Typically, a set of registers are designated to be preserved across a
+call.  If a callee wishes to use such a register, it saves the value
+that the register had at entry time in its call frame and restores it
+on exit.  The code that allocates space on the call frame stack and
+performs the save operation is called the subroutine's prologue, and the
+code that performs the restore operation and deallocates the frame is
+called its epilogue.  Typically, the prologue code is physically at the
+beginning of a subroutine and the epilogue code is at the end.
+.P
+To be able to view or modify an activation that is not on the top of
+the call frame stack, the debugger must ``virtually unwind'' the stack of
+activations until it finds the activation of interest. 
+A debugger unwinds a
+stack in steps.  Starting with the current activation it restores any
+registers that were preserved by the current activation and computes the
+predecessor's CFA and code location.  This has the logical effect of
+returning from the current subroutine to its predecessor.  We say that
+the debugger virtually unwinds the stack because it preserves enough
+information to be able to ``rewind'' the stack back to the state it was
+in before it attempted to unwind it.
+.P
+The unwinding operation needs to know where registers are saved and how
+to compute the predecessor's CFA and code location.  When considering
+an architecture-independent way of encoding this information one has to
+consider a number of special things.
+.BL
+.LI
+Prologue and epilogue code is not always in distinct blocks at the
+beginning and end of a subroutine.  It is common to duplicate the
+epilogue code at the site of each return from the code.  Sometimes
+a compiler breaks up the register save/unsave operations and moves
+them into the body of the subroutine to just where they are needed.
+.LI
+Compilers use different ways to manage the call frame.  Sometimes
+they use a frame pointer register, sometimes not.
+.LI
+The algorithm to compute the CFA changes as you progress through
+the prologue and epilogue code.  (By definition, the CFA value
+does not change.)
+.LI
+Some subroutines have no call frame.
+.LI
+Sometimes a register is saved in another register that by
+convention does not need to be saved.
+.LI
+Some architectures have special instructions that
+perform some or all of the register management in one instruction,
+leaving special information on the stack that indicates how
+registers are saved.
+.LI
+Some architectures treat return address values
+specially.  For example, in one architecture, 
+the call instruction guarantees that the low order two
+bits will be zero and the return instruction ignores those bits.
+This leaves two bits of storage that are available to other uses
+that must be treated specially.
+.LE
+.R
+.H 3 "Structure of Call Frame Information"
+.IX call frame information, structure
+DWARF supports virtual unwinding by defining an architecture independent
+basis for recording how procedures save and restore registers throughout
+their lifetimes.  This basis must be augmented on some machines with
+specific information that is defined by either an architecture specific
+ABI authoring committee, a hardware vendor, or a compiler producer.
+.IX ABI
+.IX vendor extensions
+The body defining a specific augmentation is referred to
+below as the ``augmenter.''
+.P
+Abstractly, this mechanism describes a very large table that has the
+following structure:
+.TS
+center;
+l l l l l l
+l s s s s s.
+LOC  CFA   R0   R1   ...  RN
+L0
+L1
+\...
+LN
+.TE
+.P
+The first column indicates an address for every location that contains
+code in a program.  (In shared objects, this is an object-relative
+offset.)  The remaining columns contain virtual unwinding rules that are
+associated with the indicated location.  The first column of the rules
+defines the CFA rule which is a register and a signed offset that are
+added together to compute the CFA value.
+.P
+The remaining columns are labeled by register number.  This includes
+some registers that have special designation on some architectures such
+as the PC and the stack pointer register.  (The actual mapping of
+registers for a particular architecture is performed by the augmenter.)
+The register columns contain rules that describe
+whether a given register has been saved and the rule to find 
+the value for the register in the previous frame.
+.P
+The register rules are:
+.IX call frame information, register rules
+.VL 20
+.LI "undefined"
+A register that has this rule has no value in the
+previous frame.  (By convention, it is not preserved by a callee.)
+.LI "same value"
+This register has not been modified from the
+previous frame.  (By convention, it is preserved by the callee,
+but the callee has not modified it.)
+.LI "offset(N)"
+The previous value of this register is saved at the address CFA+N where
+CFA is the current CFA value and N is a signed offset.
+.LI "register(R)"
+The previous value of this register is stored in
+another register numbered R.
+.LI "architectural"
+The rule is defined externally to this specification by the augmenter.
+.LE
+.P
+.I
+This table would be extremely large if actually constructed as
+described.  Most of the entries at any point in the table are identical
+to the ones above them.  The whole table can be represented quite
+compactly by recording just the differences starting at the beginning
+address of each subroutine in the program.
+.R
+.P
+The virtual unwind information is encoded in a self-contained section
+called 
+.Cf .debug_frame . 
+.IX \f(CW.debug_frame\fP %debugaf
+Entries in a 
+.Cf .debug_frame
+section are aligned on
+.IX call frame information, Common Information Entry
+an addressing unit boundary and come in two forms: A Common Information
+Entry (CIE) and a Frame Description Entry (FDE).
+Sizes of data objects used in the encoding of the 
+.Cf .debug_frame
+section are described in terms of the same data definitions
+used for the line number information (see section 6.2.1).
+.P
+A Common Information Entry holds information that is shared among many
+Frame Descriptors.  There is at least one CIE in every non-empty
+.Cf .debug_frame

+.AL
+.LI 
+\f(CWlength\fP
+.br
+A uword constant that gives the number of bytes of the CIE
+structure, not including the length field, itself 
+(length mod <addressing unit size> == 0).
+.LI 
+\f(CWCIE_id\fP
+.br
+A uword constant that is used to distinguish CIEs
+from FDEs.
+.LI
+\f(CWversion\fP
+.br
+A ubyte version number.  This number is specific to the call frame
+information and is independent of the DWARF version number.
+.LI 
+\f(CWaugmentation\fP
+.br
+A null terminated string that identifies the
+augmentation to this CIE or to the FDEs that use
+it.  If a reader encounters an augmentation string that is
+unexpected, then only the following fields can be read:
+CIE: 
+.Cf length , 
+.Cf CIE_id , 
+.Cf version , 
+.Cf augmentation ;
+FDE:
+.Cf length , 
+.Cf CIE_pointer ,

+.Cf address_range .
+If there is no augmentation, this value is a zero byte.

+An FDE contains the following fields, in order:

+\f(CWlength\fP
+.br
+A uword constant that gives the number of bytes of the header
+and instruction stream for this function (not including the length

+\f(CWCIE_pointer\fP
+.br
+A uword constant offset into the
+.Cf .debug_frame 
+section that denotes the CIE that is associated with this FDE.
+.LI 
+\f(CWinitial_location\fP
+An addressing-unit sized constant indicating

+.br
+An addressing unit sized constant indicating the
+number of bytes of program instructions described by this entry.
+.LI 
+\f(CWinstructions\fP
+.br
+A sequence of table defining instructions that are

+.LE
+.H 3 "Call Frame Instructions"
+.IX call frame information, instructions
+Each call frame instruction is defined to
+take 0 or more operands.  Some of the operands may be
+encoded as part of the opcode (see section 7.23).
+The instructions are as follows:
+.AL
+.LI 
+.Cf DW_CFA_advance_loc
+takes a single argument that represents a constant delta.
+The required action is to
+create a new table row with a location value that

+.H 1 "DATA REPRESENTATION"
+This section describes the binary representation of the debugging
+information entry itself, of the
+attribute types and of other fundamental elements described above.

+To reserve a portion of the DWARF name space and ranges of
+enumeration values for use for vendor specific extensions,
+.IX tags
+.IX types, base
+.IX base types
+.IX locations, expressions
+.IX calling conventions
+.IX call frame information
+special labels are reserved for tag names, attribute names,
+base type encodings, location operations, language names,
+calling conventions and call frame instructions.
+The labels denoting the beginning and end of the reserved value
+range for vendor specific extensions consist of the appropriate prefix (
+.Cf DW_TAG ,
+.Cf DW_AT ,
+.Cf DW_ATE ,
+.Cf DW_OP ,
+.Cf DW_LANG ,
+.CF DW_CC
+or
+.Cf DW_CFA
+respectively) followed by 
+.Cf _lo_user
+or 
+.Cf _hi_user .
+For example, for entry tags, the special labels are
+.Cf DW_TAG_lo_user
+and
+.Cf DW_TAG_hi_user .
+Values in the range between \fIprefix\fP\f(CW_lo_user\fP and
+\fIprefix\fP\f(CW_hi_user\fP
+inclusive, are reserved for vendor specific extensions.
+Vendors may use values in this range without
+conflicting with current or future system-defined values.
+All other values are reserved for use by the system.
+.P
+Vendor defined tags, attributes, base type encodings, location atoms, 
+language names, calling conventions and call frame instructions, 
+conventionally use the form
+\fIprefix\f(CW_\fIvendor_id\f(CW_\fIname\fR, where \fIvendor_id\fP is some 
+identifying character sequence chosen so as to avoid conflicts with other
+vendors.
+.P
+.IX compatibility
+To ensure that extensions added by one vendor may be safely ignored
+by consumers that do not understand those extensions, 
+the following rules should be followed:
+.AL
+.LI
+New attributes should be added in such a way that a debugger may recognize
+the format of a new attribute value without knowing the content of that
+attribute value.
+.LI
+The semantics of any new attributes should not alter the semantics of
+previously existing attributes.
+.LI
+The semantics of any new tags
+should not conflict with the semantics of previously existing tags.
+.LE
+.H 2 "Reserved Error Values"
+.IX error values
+As a convenience for consumers of DWARF information,
+the value 0 is reserved in the encodings for attribute names, attribute
+forms, base type encodings, location operations, languages,
+statement program opcodes, macro information entries and tag names
+to represent an error condition or unknown value.  DWARF does
+not specify names for these reserved values, since they do not
+represent valid encodings for the given type and should not appear
+in DWARF debugging information.
+.H 2 "Executable Objects and Shared Objects"
+The relocated addresses in the debugging information for an executable
+object are virtual addresses and the relocated addresses in the
+debugging information for a shared object are offsets relative to
+the start of the lowest segment used by that shared object.
+.P
+.I
+This requirement makes the debugging information for shared objects
+position independent.
+Virtual addresses in a shared object may be calculated by adding the
+offset to the base address at which the object was attached.
+This offset is available in the run-time linker's data structures.
+.H 2 "File Constraints"
+All debugging information entries in a relocatable object file, 
+executable object or shared
+object are required to be physically contiguous.
+.H 2 "Format of Debugging Information"
+.IX Version 2
+For each compilation unit compiled with a DWARF Version 2 producer,
+.IX compilation units
+.IX compilation units, header
+a contribution is made to the
+.Cf .debug_info
+.IX \f(CW.debug_info\fP %debugai
+section of the object file.  Each such contribution consists of
+a compilation unit header followed by a series of debugging information
+entries.  Unlike the information encoding for DWARF Version 1, Version 2
+.IX Version 1
+debugging information entries do not themselves contain the debugging
+information entry tag or the attribute name and form encodings for
+each attribute.  Instead, each debugging information entry begins with
+a code that represents an entry in a separate abbreviations table.
+This code is followed directly by a series of attribute values.
+The appropriate entry in the abbreviations table guides the interpretation
+of the information contained directly in the 
+.Cf .debug_info
+section.  Each compilation unit is associated with a particular
+abbreviation table, but multiple compilation units may share
+the same table.  
+.IX abbreviations table
+.I
+.P
+This encoding was based on the observation that typical DWARF producers
+produce a very limited number of different types of debugging information
+entries.  By extracting the common information from those entries
+into a separate table, we are able to compress the generated information.
+.R
+.H 3 "Compilation Unit Header"
+.IX compilation units, header
+The header for the series of debugging information entries contributed
+by a single compilation unit consists of the following information:
+.AL
+.LI
+A 4-byte unsigned integer representing the length of the
+.Cf .debug_info
+contribution for that compilation unit, not including the length field itself.
+.LI
+A 2-byte unsigned integer representing the version of the DWARF information
+for that compilation unit.  For DWARF Version 2, the value in this field is 2.
+.IX Version 2
+.LI
+A 4-byte unsigned offset into the 
+.Cf .debug_abbrev
+.IX \f(CW.debug_abbrev\fP %debugaab
+section.  This offset associates the compilation unit with a particular
+set of debugging information entry abbreviations.
+.LI
+.IX segmented address space
+.IX address space, segmented
+.IX addresses, size of
+A 1-byte unsigned integer representing the size in bytes of an address
+on the target architecture.  If the system uses segmented addressing,
+this value represents the size of the offset portion of an address.
+.IX addresses, offset portion
+.LE
+.P
+.I
+The compilation unit header does not replace the
+.Cf DW_TAG_compile_unit
+debugging information entry.  It is additional information that
+is represented outside the standard DWARF tag/attributes format.
+.R
+.H 3 "Debugging Information Entry"
+Each debugging information entry begins with an unsigned LEB128
+.IX debugging information entries
+number containing the abbreviation code for the entry.
+This code represents an entry within the abbreviation table associated
+with the compilation unit containing this entry.  The abbreviation
+.IX abbreviations table
+code is followed by a series of attribute values.
+.IX attributes, values
+.P
+On some architectures, there are alignment constraints on section boundaries.
+To make it easier to pad debugging information sections to satisfy
+such constraints, the abbreviation code 0 is reserved.  Debugging
+information entries consisting of only the 0 abbreviation code are considered
+null entries.
+.IX debugging information entries, null entries
+.H 3 "Abbreviation Tables"
+.IX abbreviations table
+The abbreviation tables for all compilation units are contained in
+a separate object file section called
+.Cf .debug_abbrev .
+.IX \f(CW.debug_abbrev\fP %debugaab
+As mentioned before, multiple compilation units may share the same
+abbreviation table.  
+.P
+The abbreviation table for a single compilation
+unit consists of a series of abbreviation declarations.
+Each declaration specifies the tag and attributes for a particular
+.IX tags
+.IX attributes
+form of debugging information entry.  Each declaration begins with
+an unsigned LEB128 number representing the abbreviation code itself.
+It is this code that appears at the beginning of a debugging information
+entry in the

+.P
+.IX attributes, forms
+The attribute form governs how the value of the attribute is encoded.
+The possible forms may belong to one of the following
+form classes:
+.VL 18
+.LI address
+.IX attributes, addresses
+Represented as an object of appropriate size to hold an 
+address on the target machine (\f(CWDW_FORM_addr\fP).
+This address is relocatable in
+a relocatable object file and is relocated in an 
+executable file or shared object.
+.LI "block"
+.IX attributes, blocks
+Blocks come in four forms.  The first consists of a 1-byte length
+followed by 0 to 255 contiguous information bytes  (\f(CWDW_FORM_block1\fP). 
+The second consists of a 2-byte length
+followed by 0 to 65,535 contiguous information bytes  (\f(CWDW_FORM_block2\fP). 
+The third consists of a 4-byte length
+followed by 0 to 4,294,967,295 contiguous information bytes  (\f(CWDW_FORM_block4\fP). 
+The fourth consists of an unsigned LEB128 length followed by the number
+of bytes specified by the length (\f(CWDW_FORM_block\fP).
+In all forms, the length is the number of information bytes that follow.
+The information bytes may contain any mixture of relocated (or
+relocatable) addresses, references to other debugging information entries or
+data bytes.
+.LI "constant"
+.IX attributes, constants
+There are six forms of constants:
+one, two, four and eight byte values (respectively,
+.Cf DW_FORM_data1 ,
+.Cf DW_FORM_data2 ,
+.Cf DW_FORM_data4 ,
+and
+.Cf DW_FORM_data8 ).
+.IX variable length data
+.IX LEB128
+There are also variable length constant data forms encoded
+using LEB128 numbers (see below).  Both signed (\f(CWDW_FORM_sdata\fP)
+and unsigned (\f(CWDW_FORM_udata\fP) variable length constants are available.
+.LI flag
+.IX attributes, flags
+A flag is represented as a single byte of data (\f(CWDW_FORM_flag\fP). 
+If the flag has value zero, it indicates the absence of the attribute.
+If the flag has a non-zero value, it indicates the presence of
+the attribute.
+.LI reference
+.IX attributes, references
+There are two types of reference.  The first is an
+offset relative to the first byte of the compilation unit header
+for the compilation unit containing the reference.
+The offset must refer to an entry within
+that same compilation unit.  There are five forms for this
+type of reference:
+one, two, four and eight byte offsets (respectively,
+.Cf DW_FORM_ref1 ,
+.Cf DW_FORM_ref2 ,
+.Cf DW_FORM_ref4 ,
+and
+.Cf DW_FORM_ref8 ).
+There are is also an unsigned variable length offset encoded
+using LEB128 numbers (\f(CWDW_FORM_ref_udata\fP).
+.P
+The second type of reference
+is the address of any debugging information entry within
+the same executable or shared object; it may refer to an entry
+in a different compilation unit from the unit containing the
+reference.  This type of reference (\f(CWDW_FORM_ref_addr\fP) is the
+size of an address on the target architecture; it is relocatable
+in a relocatable object file and relocated in an executable file
+or shared object.
+.P
+.I
+The use of compilation unit relative references will reduce
+the number of link-time relocations and so speed up linking.
+.P
+The use of address-type references allows for the commonization
+of information, such as types, across compilation units.
+.R
+.LI string
+.IX attributes, strings
+A string is a sequence of contiguous non-null bytes followed by one null
+byte.  A string may be represented immediately in the debugging information
+entry itself (\f(CWDW_FORM_string\fP), or may be represented as a 4-byte offset
+into a string table contained in the 
+.Cf .debug_str
+.IX \f(CW.debug_str\fP %debugas

+The special constant data forms
+.Cf DW_FORM_sdata
+and
+.Cf DW_FORM_udata
+are encoded using ``Little Endian Base 128'' (LEB128)
+numbers. LEB128 is a scheme for encoding integers densely that
+exploits the assumption that most integers are small in magnitude.
+(This encoding is equally suitable whether the target machine
+architecture represents data in big-endian or little-endian order.
+It is ``little endian'' only in the sense that it avoids using space
+to represent the ``big'' end of an unsigned integer, when the big
+end is all zeroes or sign extension bits).
+.P
+.Cf DW_FORM_udata
+(unsigned LEB128) numbers are encoded as follows:
+start at the
+low order end of an unsigned integer and chop it into 7-bit chunks.
+Place each chunk into the low order 7 bits of a byte.  Typically,
+several of the high order bytes will be zero; discard them.  Emit the
+remaining bytes in a stream, starting with the low order byte;
+set the high order bit on each byte except the last emitted byte.
+The high bit of zero on the last byte indicates to the decoder
+that it has encountered the last byte.
+.P
+The integer zero is a special case, consisting of a single zero byte.

+The encoding for 
+.Cf DW_FORM_sdata
+(signed, 2s complement LEB128) numbers is similar, except that the
+criterion for discarding high order bytes is not whether they are
+zero, but whether they consist entirely of sign extension bits.
+Consider the 32-bit integer 
+.Cf -2 .
+The three high level bytes of the number are sign extension, thus LEB128
+would represent it as a single byte containing the low order 7 bits,
+with the high order bit cleared to indicate the end of the byte
+stream.  Note that there is nothing within the LEB128 representation
+that indicates whether an encoded number is signed or unsigned.

+.H 1 "FUTURE DIRECTIONS"
+The \*(iX \*(tE is working on a specification for a set of interfaces
+for reading DWARF information, that will hide changes in the
+representation of that information from its consumers.  It is
+hoped that using these interfaces will make the transition from
+DWARF Version 1 to Version 2 much simpler and will make it
+easier for a single consumer to support objects using either
+Version 1 or Version 2 DWARF.
+.P
+A draft of this specification is available for review from
+\*(iX. The \*(tE wishes to stress, however, that the specification
+is still in flux.
+.OP
+.HU "Appendix 1 -- Current Attributes by Tag Value"
+.P
+The list below enumerates the attributes that are most applicable to each type
+of debugging information entry.
+DWARF does not in general require that a given debugging information
+entry contain a particular attribute or set of attributes.  Instead, a
+DWARF producer is free to generate any, all, or none of the attributes
+described in the text as being applicable to a given entry.  Other
+attributes (both those defined within this document but not explicitly
+associated with the entry in question, and new, vendor-defined ones)
+may also appear in a given debugging entry.
+Therefore, the list may be
+taken as instructive, but cannot be considered definitive.

+.LI
+Instruction operands are typically of the form:

+    This function is the heart of the debug_frame stuff.  Don't even
+    think of reading this without reading both the Libdwarf and 
+    consumer API carefully first.  This function basically executes     
+    frame instructions contained in a Cie or an Fde, but does in a      
+    number of different ways depending on the information sought.       
+    Start_instr_ptr points to the first byte of the frame instruction    
+    stream, and final_instr_ptr to the to the first byte after the       
+    last.                                                                
+                                                                        
+    The offsets returned in the frame instructions are factored.  That   
+    is they need to be multiplied by either the code_alignment_factor    
+    or the data_alignment_factor, as appropriate to obtain the actual      
+    offset.  This makes it possible to expand an instruction stream      
+    without the corresponding Cie.  However, when an Fde frame instr     
+    sequence is being expanded there must be a valid Cie with a pointer  
+    to an initial table row.                                             
+                                                                         
+
+    If successful, returns DW_DLV_OK
+        And sets returned_count thru the pointer
+        if make_instr is true.
+        If make_instr is false returned_count 
+        should NOT be used by the caller (returned_count
+        is set to 0 thru the pointer by this routine...)
+    If unsuccessful, returns DW_DLV_ERROR
+        and sets returned_error to the error code
+
+    It does not do a whole lot of input validation being a private 
+    function.  Please make sure inputs are valid.
+                                                                        
+    (1) If make_instr is true, it makes a list of pointers to              
+    Dwarf_Frame_Op structures containing the frame instructions          
+    executed.  A pointer to this list is returned in ret_frame_instr.    
+    Make_instr is true only when a list of frame instructions is to be   
+    returned.  In this case since we are not interested in the contents  
+    of the table, the input Cie can be NULL.  This is the only case
+    where the inpute Cie can be NULL.
+
+    (2) If search_pc is true, frame instructions are executed till       
+    either a location is reached that is greater than the search_pc_val
+    provided, or all instructions are executed.  At this point the       
+    last row of the table generated is returned in a structure.          
+    A pointer to this structure is supplied in table.                    
+                                                                    
+    (3) This function is also used to create the initial table row       
+    defined by a Cie.  In this case, the Dwarf_Cie pointer cie, is       
+    NULL.  For an FDE, however, cie points to the associated Cie.        
+
+    make_instr - make list of frame instr? 0/1
+    ret_frame_instr -  Ptr to list of ptrs to frame instrs
+    search_pc  - Search for a pc value?  0/1
+    search_pc_val -  Search for this pc value
+    initial_loc - Initial code location value.
+    start_instr_ptr -   Ptr to start of frame instrs.
+    final_instr_ptr -   Ptr just past frame instrs. 
+    table       -     Ptr to struct with last row. 
+    cie     -   Ptr to Cie used by the Fde.
+
+    Different cies may have distinct address-sizes, so the cie
+    is used, not de_pointer_size.

+/*  The dwarf 2.0 standard dictates that only the following
+    fields can be read when an unexpected augmentation string
+    (in the cie) is encountered: CIE length, CIE_id, version and
+    augmentation; FDE: length, CIE pointer, initial location and
+    address range. Unfortunately, with the above restrictions, it
+    is impossible to read the instruction table from a CIE or a FDE
+    when a new augmentation string is encountered.
+    To fix this problem, the following layout is used, if the
+    augmentation string starts with the string "z".
+        CIE                        FDE
+        length                     length
+        CIE_id                     CIE_pointer
+        version                    initial_location
+        augmentation               address_range
+
+        -                          length_of_augmented_fields (*NEW*)
+        code_alignment_factor      Any new fields as necessary
+        data_alignment_factor      instruction_table
+        return_address
+        length_of_augmented fields
+        Any new fields as necessary
+        initial_instructions
+  
+    The type of all the old data items are the same as what is
+    described in dwarf 2.0 standard. The length_of_augmented_fields
+    is an LEB128 data item that denotes the size (in bytes) of
+    the augmented fields (not including the size of
+    "length_of_augmented_fields" itself).
+ 
+    Handling of cie augmentation strings is necessarly a heuristic.
+    See dwarf_frame.c for the currently known augmentation strings.
+
+
+    ---START SGI-ONLY COMMENT:
+    SGI-IRIX versions of cie or fde  were intended to use "z1", "z2" as the
+    augmenter strings if required for new augmentation.
+    However, that never happened (as of March 2005).
+  
+    The fde's augmented by the string "z" have a new field 
+    (signed constant, 4 byte field)
+    called offset_into_exception_tables, following the 
+    length_of_augmented field.   This field contains an offset 
+    into the "_MIPS_eh_region", which describes
+    the IRIX CC exception handling tables.
+    ---END SGI-ONLY COMMENT
+ 
+
+    GNU .eh_frame has an augmentation string of z[RLP]* (gcc 3.4)
+    The similarity to IRIX 'z' (and proposed but never
+    implemented IRIX z1, z2 etc) was confusing things.
+    If the section is .eh_frame then 'z' means GNU exception
+    information 'Augmentation Data' not IRIX 'z'.
+    See The Linux Standard Base Core Specification version 3.0

+/*  gennames.c
+    Prints routines to return constant name for the associated value
+    (such as the TAG name string for a particular tag).
+  
+    The input is dwarf.h
+    For each set of names with a common prefix, we create a routine
+    to return the name given the value.
+    Also print header file that gives prototypes of routines.
+    To handle cases where there are multiple names for a single
+    value (DW_AT_* has some due to ambiguities in the DWARF2 spec)
+    we take the first of a given value as the definitive name.
+    TAGs, Attributes, etc are given distinct checks.
+  
+    There are multiple output files as some people find one
+    form more pleasant than the other.
+  
+    The doprinting argument is so that when used by tag_tree.c,
+    and tag_attr.c that we don't get irritating messages on stderr
+    when those dwarfdump built-time applications are run.
+  
+    Some compilers generate better code for switch statements than
+    others, so the -s and -t options let the user decide which
+    is better for their compiler (when building dwarfdump):
+    a simple switch or code doing binary search.
+    This choice affects the runtime speed of dwarfdump.  */

+.H 1 "INTRODUCTION"
+This document describes an interface to \fIlibdwarf\fP, a
+library of functions to provide access to DWARF debugging information
+records, DWARF line number information, DWARF address range and global 
+names information, weak names information, DWARF frame description 
+information, DWARF static function names, DWARF static variables, and 
+DWARF type information.
+.P
+The document has long mentioned the  
+"Unix International Programming Languages Special Interest Group" 
+(PLSIG), under whose auspices the
+DWARF committee was formed around 1991.
+"Unix International"  
+was disbanded in the 1990s and no longer exists.
+.P
+The DWARF committee published DWARF2 July 27, 1993.
+.P
+In the mid 1990s this document and the library it describes
+(which the committee never endorsed, having decided
+not to endorse or approve any particular library interface)
+was made available on the internet by Silicon Graphics, Inc.
+.P
+In 2005 the DWARF committee began an affiliation with FreeStandards.org.
+In 2007 FreeStandards.org merged with The Linux Foundation.
+The DWARF committee dropped its affiliation with FreeStandards.org
+in 2007 and established the dwarfstd.org website.
+See "http://www.dwarfstd.org" for current
+information on standardization activities 
+and a copy of the standard.

+
+.H 2 "Purpose and Scope"
+The purpose of this document is to document a library of functions 
+to access DWARF debugging information. There is no effort made in 
+this document to address the creation of these records as those
+issues are addressed separately 
+(see "A Producer Library Interface to DWARF").
+
+.P
+Additionally, the focus of this document is the functional interface,
+and as such, implementation as well as optimization issues are
+intentionally ignored.
+
+
+.H 2 "Document History"
+.P
+A document was written about 1991 which had similar
+layout and interfaces. 
+Written by people from Hal Corporation,
+That document described a library for reading DWARF1.
+The authors distributed paper copies to the committee
+with the clearly expressed intent to propose the document as
+a supported interface definition.
+The committee decided not to pursue a library definition.
+.P
+SGI wrote the document you are now reading in 1993
+with a similar layout and content and organization, but 
+it was complete document rewrite with the intent to read DWARF2
+(the DWARF version then in existence).
+The intent was (and is) to also cover
+future revisions of DWARF.
+All the function interfaces were changed 
+in 1994 to uniformly
+return a simple integer success-code (see DW_DLV_OK etc), 
+generally following
+the recommendations in the chapter titled "Candy Machine Interfaces"
+of "Writing Solid Code", a book by
+Steve Maguire (published by Microsoft Press).
+.H 2 "Definitions"
+DWARF debugging information entries (DIEs) are the segments of information 
+placed in the \f(CW.debug_*\fP sections by compilers, assemblers, and 
+linkage editors that, in conjunction with line number entries, are 
+necessary for symbolic source-level debugging.  
+Refer to the latest
+"\fIDWARF Debugging Information Format\fP" from www.dwarfstd.org for a more 
+complete description of these entries.
+
+.P
+This document adopts all the terms and definitions in "\fIDWARF Debugging 
+Information Format\fP" versions 2,3, and 4.  
+It originally focused on the implementation at
+Silicon Graphics, Inc., but now
+attempts to be more generally useful.
+
+.H 2 "Overview"
+The remaining sections of this document describe the proposed interface
+to \f(CWlibdwarf\fP, first by describing the purpose of additional types
+defined by the interface, followed by descriptions of the available 
+operations.  This document assumes you are thoroughly familiar with the 
+information contained in the \fIDWARF Debugging Information Format\fP 
+document. 
+.P
+We separate the functions into several categories to emphasize that not 
+all consumers want to use all the functions.  We call the categories 
+Debugger, Internal-level, High-level, and Miscellaneous not because one is more 
+important than another but as a way of making the rather large set of 
+function calls easier to understand.
+.P
+Unless otherwise specified, all functions and structures should be
+taken as being designed for Debugger consumers.
+.P
+The Debugger Interface of this library is intended to be used by debuggers. 
+The interface is low-level (close to dwarf) but suppresses irrelevant detail.
+A debugger will want to absorb all of some sections at startup and will 
+want to see little or nothing of some sections except at need.  And even 
+then will probably want to absorb only the information in a single compilation 
+unit at a time.  A debugger does not care about
+implementation details of the library.
+.P
+The Internal-level Interface is for a DWARF prettyprinter and checker.  
+A 
+thorough prettyprinter will want to know all kinds of internal things 
+(like actual FORM numbers and actual offsets) so it can check for 
+appropriate structure in the DWARF data and print (on request) all 
+that internal information for human users and libdwarf authors and 
+compiler-writers.  
+Calls in this interface provide data a debugger 
+does not care about.
+.P
+The High-level Interface is for higher level access
+(it is not really a high level interface!).  
+Programs such as 
+disassemblers will want to be able to display relevant information 
+about functions and line numbers without having to invest too much 
+effort in looking at DWARF.
+.P
+The miscellaneous interface is just what is left over: the error handler 
+functions.
+.P
+The following is a brief mention of the changes in this libdwarf from 
+the libdwarf draft for DWARF Version 1 and recent changes.
+.H 2 "Items Changed"
+.P
+Added new functions (some for libdwarf client code) 
+and internal logic support for the 
+DWARF4 .debug_types section.
+The new functions are
+dwarf_next_cu_header_c(),
+dwarf_siblingof_b(), dwarf_offdie_b(),
+dwarf_get_cu_die_offset_given_cu_header_offset_b(),
+dwarf_get_die_infotypes_flag(),
+dwarf_get_section_max_offsets_b().
+.P
+New functions and logic support additional detailed error reporting
+so that more compiler bugs can be reported sensibly 
+by consumer code (as opposed
+to having libdwarf just assume 
+things are ok and blindly continuing on
+with erroneous data).
+November 20, 2010
+.P
+It seems impossible to default to both DW_FRAME_CFA_COL
+and DW_FRAME_CFA_COL3 in a single build of libdwarf,
+so the default is now unambiguously DW_FRAME_CFA_COL3
+unless the configure option --enable-oldframecol 
+is specified at configure time.
+The function dwarf_set_frame_cfa_value()
+may be used to override the default : using that function gives
+consumer applications full control (its use is highly
+recommended). 
+(January 17,2010)
+.P
+Added dwarf_set_reloc_application() and the default
+automatic application of Elf 'rela' relocations
+to DWARF sections (such rela sections appear in .o files, not
+in executables or shared objects, in general).
+The  dwarf_set_reloc_application() routine lets a consumer
+turn off the automatic application of 'rela' relocations
+if desired (it is not clear why anyone would really want to do that,
+but possibly a consumer could write its own relocation application).
+An example application that traverses a set of DIEs
+was added to the new dwarfexample directory (not
+in this libdwarf directory, but in parallel to it).
+(July 10, 2009)
+.P
+Added dwarf_get_TAG_name() (and the FORM AT and so on)
+interface functions so applications can get the string
+of the TAG, Attribute, etc as needed. (June 2009)
+.P
+Added dwarf_get_ranges_a() and dwarf_loclist_from_expr_a()
+functions which add arguments allowing a correct address_size
+when the address_size varies by compilation unit (a varying
+address_size is quite rare as of May 2009).
+(May 2009)
+.P
+Added dwarf_set_frame_same_value(), and
+dwarf_set_frame_undefined_value() to complete
+the set of frame-information functions needed to allow
+an application get all frame information
+returned correctly (meaning that it
+can be correctly interpreted) for all ABIs.  
+Documented dwarf_set_frame_cfa_value().
+Corrected spelling to dwarf_set_frame_rule_initial_value().
+(April 2009).
+.P
+Added support for various DWARF3 features, but primarily
+a new frame-information interface tailorable at run-time
+to more than a single ABI.
+See dwarf_set_frame_rule_initial_value(), dwarf_set_frame_rule_table_size(),
+dwarf_set_frame_cfa_value().
+See also dwarf_get_fde_info_for_reg3() and
+dwarf_get_fde_info_for_cfa_reg3().  (April 2006)
+.P
+Added support for DWARF3 .debug_pubtypes section.
+Corrected various leaks (revising dealloc() calls, adding
+new functions) and corrected dwarf_formstring() documentation.
+.P 
+Added dwarf_srclines_dealloc() as the previous deallocation
+method documented for data returned by
+dwarf_srclines() was incapable of freeing
+all the allocated storage (14 July 2005).
+.P
+dwarf_nextglob(), dwarf_globname(), and dwarf_globdie() were all changed 
+to operate on the items in the .debug_pubnames section.
+.P
+All functions were modified to return solely an error code.
+Data is returned through pointer arguments.
+This makes writing safe and correct library-using-code far easier.
+For justification for this approach, see 
+the chapter titled "Candy Machine Interfaces"
+in the book "Writing Solid Code" by
+Steve Maguire.
+
+.H 2 "Items Removed"
+.P
+Dwarf_Type
+was removed since types are no longer special.
+.P
+dwarf_typeof()
+was removed since types are no longer special.
+.P
+Dwarf_Ellist
+was removed since element lists no longer are a special format.
+.P
+Dwarf_Bounds
+was removed since bounds have been generalized.
+.P
+dwarf_nextdie()
+was replaced by dwarf_next_cu_header() to reflect the
+real way DWARF is organized.
+The dwarf_nextdie() was only useful for getting to compilation
+unit beginnings, so it does not seem harmful to remove it in favor
+of a more direct function.
+.P
+dwarf_childcnt() is removed on grounds
+that no good use was apparent.
+.P
+dwarf_prevline() and dwarf_nextline() were removed on grounds this
+is better left to a debugger to do.
+Similarly, dwarf_dieline() was removed.
+.P
+dwarf_is1stline() was removed as it was not meaningful for the
+revised DWARF line operations.
+.P
+Any libdwarf implementation might well decide to support all the
+removed functionality and to retain the DWARF Version 1 meanings
+of that functionality.  
+This would be difficult because the
+original libdwarf draft
+specification used traditional C library interfaces which
+confuse the values returned by successful calls with
+exceptional conditions like failures and 'no more data' indications.

+.H 1 "Types Definitions"
+
+.H 2 "General Description"
+The \fIlibdwarf.h\fP header file contains typedefs and preprocessor 
+definitions of types and symbolic names used to reference objects 
+of \fIlibdwarf\fP. The types defined by typedefs contained in 
+\fIlibdwarf.h\fP all use the convention of adding \f(CWDwarf_\fP 
+as a prefix and can be placed in three categories: 
+
+.BL
+.LI
+Scalar types : The scalar types defined in \fIlibdwarf.h\fP are
+defined primarily for notational convenience and identification.
+Depending on the individual definition, they are interpreted as a 
+value, a pointer, or as a flag.
+.LI
+Aggregate types : Some values can not be represented by a single 
+scalar type; they must be represented by a collection of, or as a 
+union of, scalar and/or aggregate types. 
+.LI
+Opaque types : The complete definition of these types is intentionally
+omitted; their use is as handles for query operations, which will yield
+either an instance of another opaque type to be used in another query, or 
+an instance of a scalar or aggregate type, which is the actual result.
+.P
+
+.H 2 "Scalar Types"
+The following are the defined by \fIlibdwarf.h\fP:
+
+.DS
+\f(CW
+typedef int                Dwarf_Bool;
+typedef unsigned long long Dwarf_Off;
+typedef unsigned long long Dwarf_Unsigned;
+typedef unsigned short     Dwarf_Half;
+typedef unsigned char      Dwarf_Small;
+typedef signed long long   Dwarf_Signed;
+typedef unsigned long long Dwarf_Addr;
+typedef void 		   *Dwarf_Ptr;
+typedef void   (*Dwarf_Handler)(Dwarf_Error *error, Dwarf_Ptr errarg);
+.DE
+
+.nr aX \n(Fg+1
+Dwarf_Ptr is an address for use by the host program calling the library,
+not for representing pc-values/addresses within the target object file.
+Dwarf_Addr is for pc-values within the target object file.  The sample 
+scalar type assignments above are for a \fIlibdwarf.h\fP that can read 
+and write
+32-bit or 64-bit binaries on a 32-bit or 64-bit host machine.
+The types must be  defined appropriately
+for each implementation of libdwarf.
+A description of these scalar types in the SGI/MIPS
+environment is given in Figure \n(aX.

+.FG "Scalar Types"
+.DE
+
+.H 2 "Aggregate Types"
+The following aggregate types are defined by 
+\fIlibdwarf.h\fP:
+\f(CWDwarf_Loc\fP,
+\f(CWDwarf_Locdesc\fP,
+\f(CWDwarf_Block\fP, 
+\f(CWDwarf_Frame_Op\fP. 
+\f(CWDwarf_Regtable\fP. 
+\f(CWDwarf_Regtable3\fP. 
+While most of \f(CWlibdwarf\fP acts on or returns simple values or
+opaque pointer types, this small set of structures seems useful.
+
+.H 3 "Location Record"
+The \f(CWDwarf_Loc\fP type identifies a single atom of a location description
+or a location expression.
+
+.DS
+\f(CWtypedef struct {
+        Dwarf_Small        lr_atom;
+        Dwarf_Unsigned     lr_number;
+        Dwarf_Unsigned     lr_number2;
+        Dwarf_Unsigned     lr_offset;  
+} Dwarf_Loc;\fP
+.DE
+
+The \f(CWlr_atom\fP identifies the atom corresponding to the \f(CWDW_OP_*\fP 
+definition in \fIdwarf.h\fP and it represents the operation to be performed 
+in order to locate the item in question.
+
+.P
+The \f(CWlr_number\fP field is the operand to be used in the calculation
+specified by the \f(CWlr_atom\fP field; not all atoms use this field.
+Some atom operations imply signed numbers so it is necessary to cast 
+this to a \f(CWDwarf_Signed\fP type for those operations.
+
+.P
+The \f(CWlr_number2\fP field is the second operand specified by the 
+\f(CWlr_atom\fP field; only \f(CWDW_OP_BREGX\fP has this field.  Some 
+atom operations imply signed numbers so it may be necessary to cast 
+this to a \f(CWDwarf_Signed\fP type for those operations.
+.P
+For a \f(CWDW_OP_implicit_value\fP operator the \f(CWlr_number2\fP
+field is a pointer to the bytes of the value. The field pointed to
+is \f(CWlr_number\fP bytes long.  There is no explicit terminator.
+Do not attempt to \f(CWfree\fP the bytes which \f(CWlr_number2\fP
+points at and do not alter those bytes. The pointer value
+remains valid till the open Dwarf_Debug is closed.
+This is a rather ugly use of a host integer to hold a pointer. 
+You will normally have to do a 'cast' operation to use the value.

+.H 1 "Error Handling"
+The method for detection and disposition of error conditions that arise 
+during access of debugging information via \fIlibdwarf\fP is consistent
+across all \fIlibdwarf\fP functions that are capable of producing an
+error.  This section describes the method used by \fIlibdwarf\fP in
+notifying client programs of error conditions. 
+
+.P
+Most functions within \fIlibdwarf\fP accept as an argument a pointer to 
+a \f(CWDwarf_Error\fP descriptor where a \f(CWDwarf_Error\fP descriptor 
+is stored if an error is detected by the function.  Routines in the client 
+program that provide this argument can query the \f(CWDwarf_Error\fP 
+descriptor to determine the nature of the error and perform appropriate 
+processing. 
+
+.P
+A client program can also specify a function to be invoked upon detection 
+of an error at the time the library is initialized (see \f(CWdwarf_init()\fP). 
+When a \fIlibdwarf\fP routine detects an error, this function is called
+with two arguments: a code indicating the nature of the error and a pointer
+provided by the client at initialization (again see \f(CWdwarf_init()\fP).
+This pointer argument can be used to relay information between the error 
+handler and other routines of the client program.  A client program can 
+specify or change both the error handling function and the pointer argument 
+after initialization using \f(CWdwarf_seterrhand()\fP and 
+\f(CWdwarf_seterrarg()\fP.
+
+.P
+In the case where \fIlibdwarf\fP functions are not provided a pointer
+to a \f(CWDwarf_Error\fP descriptor, and no error handling function was 
+provided at initialization, \fIlibdwarf\fP functions terminate execution 
+by calling \f(CWabort(3C)\fP.
+
+.P
+The following lists the processing steps taken upon detection of an
+error:
+.AL 1
+.LI
+Check the \f(CWerror\fP argument; if not a \fINULL\fP pointer, allocate
+and initialize a \f(CWDwarf_Error\fP descriptor with information describing
+the error, place this descriptor in the area pointed to by \f(CWerror\fP,
+and return a value indicating an error condition.
+.LI
+If an \f(CWerrhand\fP argument was provided to \f(CWdwarf_init()\fP
+at initialization, call \f(CWerrhand()\fP passing it the error descriptor
+and the value of the \f(CWerrarg\fP argument provided to \f(CWdwarf_init()\fP. 
+If the error handling function returns, return a value indicating an 
+error condition.
+.LI
+Terminate program execution by calling \f(CWabort(3C)\fP.
+.LE
+.SP
+
+In all cases, it is clear from the value returned from a function 
+that an error occurred in executing the function, since
+DW_DLV_ERROR is returned.
+.P
+As can be seen from the above steps, the client program can provide
+an error handler at initialization, and still provide an \f(CWerror\fP
+argument to \fIlibdwarf\fP functions when it is not desired to have
+the error handler invoked.
+
+.P
+If a \f(CWlibdwarf\fP function is called with invalid arguments, the 
+behavior is undefined.  In particular, supplying a \f(CWNULL\fP pointer 
+to a \f(CWlibdwarf\fP function (except where explicitly permitted), 
+or pointers to invalid addresses or uninitialized data causes undefined 
+behavior; the return value in such cases is undefined, and the function 
+may fail to invoke the caller supplied error handler or to return a 
+meaningful error number.  Implementations also may abort execution for 
+such cases.
+
+.P
+Some errors are so inconsequential that it does not warrant
+rejecting an object or returning an error.
+An example would be a frame length not being a multiple of
+an address-size (right now this is the only such inconsequential
+error).  To make it possible for a client  to report such errors
+the function \f(CWdwarf_get_harmless_error_list\fP
+returns strings with error text in them.  This function
+may be ignored if client code does not want to bother with
+such error reporting. See \f(CWDW_DLE_DEBUG_FRAME_LENGTH_NOT_MULTIPLE\fP
+in the libdwarf source code.

+.P
+If \f(CWDW_DLV_ERROR\fP is returned and a pointer to a \f(CWDwarf_Error\fP

+After the \f(CWDwarf_Error\fP is no longer of interest,

+If \f(CWDW_DLV_NO_ENTRY\fP is returned no pointer value in the

+.P
+If \f(CWDW_DLV_OK\fP is returned, the \f(CWDwarf_Error\fP pointer, if

+In this case calls (depending on the exact function
+returning the error) to \f(CWdwarf_dealloc()\fP may be appropriate

+and this document refers to the function as 
+returning the value through *err or *return_lineoff or

+Sometimes other similar phrases are used.
+
+.H 1 "Memory Management"
+Several of the functions that comprise \fIlibdwarf\fP return pointers 
+(opaque descriptors) to structures that have been dynamically allocated 
+by the library.  To aid in the management of dynamic memory, the function 
+\f(CWdwarf_dealloc()\fP is provided to free storage allocated as a result 
+of a call to a \fIlibdwarf\fP function.  This section describes the strategy 
+that should be taken by a client program in managing dynamic storage.
+
+.H 2 "Read-only Properties"
+All pointers (opaque descriptors) returned by or as a result of a 
+\fIlibdwarf Consumer Library\fP 
+call should be assumed to point to read-only memory.  
+The results are undefined for \fIlibdwarf\fP  clients that attempt 
+to write to a region pointed to by a value returned by a 
+\fIlibdwarf Consumer Library\fP 
+call.
+
+.H 2 "Storage Deallocation"
+See the section "Returned values in the functional interface",
+above, for the general rules where 
+calls to \f(CWdwarf_dealloc()\fP
+is appropriate.
+.P
+In some cases the pointers returned by a \fIlibdwarf\fP call are pointers
+to data which is not freeable.  
+The library knows from the allocation type
+provided to it whether the space is freeable or not and will not free 
+inappropriately when \f(CWdwarf_dealloc()\fP is called.  
+So it is vital
+that \f(CWdwarf_dealloc()\fP be called with the proper allocation type.
+.P
+For most storage allocated by \fIlibdwarf\fP, the client can free the
+storage for reuse by calling \f(CWdwarf_dealloc()\fP, providing it with 
+the \f(CWDwarf_Debug\fP descriptor specifying the object for which the
+storage was allocated, a pointer to the area to be free-ed, and an 
+identifier that specifies what the pointer points to (the allocation
+type).  For example, to free a \f(CWDwarf_Die die\fP belonging the the
+object represented by \f(CWDwarf_Debug dbg\fP, allocated by a call to 
+\f(CWdwarf_siblingof()\fP, the call to \f(CWdwarf_dealloc()\fP would be:
+.DS
+    \f(CWdwarf_dealloc(dbg, die, DW_DLA_DIE);\fP
+.DE
+
+To free storage allocated in the form of a list of pointers (opaque 
+descriptors), each member of the list should be deallocated, followed 
+by deallocation of the actual list itself.  The following code fragment 
+uses an invocation of \f(CWdwarf_attrlist()\fP as an example to illustrate 
+a technique that can be used to free storage from any \fIlibdwarf\fP 
+routine that returns a list:
+.DS
+\f(CWDwarf_Unsigned atcnt;
+Dwarf_Attribute *atlist;
+int errv;
+
+errv = dwarf_attrlist(somedie, &atlist,&atcnt, &error);
+if (errv == DW_DLV_OK) {
+
+        for (i = 0; i < atcnt; ++i) {
+                /* use atlist[i] */
+                dwarf_dealloc(dbg, atlist[i], DW_DLA_ATTR);
+        }
+        dwarf_dealloc(dbg, atlist, DW_DLA_LIST);
+}\fP
+.DE
+
+The \f(CWDwarf_Debug\fP returned from \f(CWdwarf_init()\fP 
+or \f(CWdwarf_elf_init()\fP 
+cannot be freed using \f(CWdwarf_dealloc()\fP.
+The function \f(CWdwarf_finish()\fP will deallocate all dynamic storage
+associated with an instance of a \f(CWDwarf_Debug\fP type.  In particular,
+it will deallocate all dynamically allocated space associated with the
+\f(CWDwarf_Debug\fP descriptor, and finally make the descriptor invalid.
+
+An \f(CWDwarf_Error\fP returned from \f(CWdwarf_init()\fP
+or \f(CWdwarf_elf_init()\fP
+in case of a failure cannot be freed
+using \f(CWdwarf_dealloc()\fP.
+The only way to free the \f(CWDwarf_Error\fP from either of those
+calls is to use \f2free(3)\fP directly.
+Every \f(CWDwarf_Error\fP must be freed 
+by \f(CWdwarf_dealloc()\fP except those
+returned by \f(CWdwarf_init()\fP
+or \f(CWdwarf_elf_init()\fP.
+

+        Dwarf_Error *error)\fP
+.DE
+When it returns \f(CWDW_DLV_OK\fP,
+the function \f(CWdwarf_init()\fP returns through
+\f(CWdbg\fP a \f(CWDwarf_Debug\fP descriptor 
+that represents a handle for accessing debugging records associated with 
+the open file descriptor \f(CWfd\fP.  
+\f(CWDW_DLV_NO_ENTRY\fP is returned if the object
+does not contain DWARF debugging information.
+\f(CWDW_DLV_ERROR\fP is returned if
+an error occurred.
+The 
+\f(CWaccess\fP argument indicates what access is allowed for the section. 
+The \f(CWDW_DLC_READ\fP parameter is valid
+for read access (only read access is defined or discussed in this
+document).  
+The \f(CWerrhand\fP 
+argument is a pointer to a function that will be invoked whenever an error 
+is detected as a result of a \fIlibdwarf\fP operation.  The \f(CWerrarg\fP 
+argument is passed as an argument to the \f(CWerrhand\fP function.  
+The file 
+descriptor associated with the \f(CWfd\fP argument must refer to an ordinary 
+file (i.e. not a pipe, socket, device, /proc entry, etc.), be opened with 
+the at least as much permission as specified by the \f(CWaccess\fP argument, 
+and cannot be closed or used as an argument to any system calls by the 
+client until after \f(CWdwarf_finish()\fP is called.  
+The seek position of 
+the file associated with \f(CWfd\fP is undefined upon return of 
+\f(CWdwarf_init()\fP.
+
+With SGI IRIX, by default it is allowed that the app
+\f(CWclose()\fP \f(CWfd\fP immediately after calling \f(CWdwarf_init()\fP,
+but that is not  a portable approach (that it
+works is an accidental
+side effect of the fact that SGI IRIX uses \f(CWELF_C_READ_MMAP\fP 
+in its hidden internal call to \f(CWelf_begin()\fP).
+The portable approach is to consider that \f(CWfd\fP
+must be left open till after the corresponding dwarf_finish() call
+has returned.
+
+Since \f(CWdwarf_init()\fP uses the same error handling processing as other 
+\fIlibdwarf\fP functions (see \fIError Handling\fP above), client programs 
+will generally supply an \f(CWerror\fP parameter to bypass the default actions 
+during initialization unless the default actions are appropriate.

+descriptor.  
+In systems supporting \f(CWELF\fP object files this may be 
+more space or time-efficient than using \f(CWdwarf_init()\fP.
+The client is allowed to use the \f(CWElf *\fP pointer
+for its own purposes without restriction during the time the 
+\f(CWDwarf_Debug\fP

+When it returns \f(CWDW_DLV_OK\fP,

+pointer \f(CWelf\fP the \f(CWElf *\fP handle
+used to access the object represented by the \f(CWDwarf_Debug\fP
+descriptor \f(CWdbg\fP.  It returns \f(CWDW_DLV_ERROR\fP on error.
+
+Because \f(CWint dwarf_init()\fP opens an Elf descriptor
+on its fd and \f(CWdwarf_finish()\fP does not close that
+descriptor, an app should use \f(CWdwarf_get_elf\fP
+and should call \f(CWelf_end\fP with the pointer returned
+through the \f(CWElf**\fP handle created by \f(CWint dwarf_init()\fP.

+associated with the descriptor \f(CWdbg\fP, and invalidates \f(CWdbg\fP.  
+It returns \f(CWDW_DLV_ERROR\fP if there is an error during the
+finishing operation.  It returns \f(CWDW_DLV_OK\fP 
+for a successful operation.
+
+Because \f(CWint dwarf_init()\fP opens an Elf descriptor
+on its fd and \f(CWdwarf_finish()\fP does not close that

+\f(CWint dwarf_set_reloc_application()\fP sets a global flag
+and returns the previous value of the global flag.
+
+If the reloc_application global flag is non-zero (the default)
+then the applicable .rela section (if one exists) will be
+processed and applied to any DWARF section when it is read in.
+If the reloc_application global flag is zero no such

+(MIPS/IRIX 64bit dwarf was created years before DWARF3

+and returns 4 if the dwarf uses the standard 64bit
+extension (the 4 is the size in bytes of the 0xffffffff

+dwarf_set_frame_rule_table_size()
+dwarf_set_frame_cfa_value(), 
+dwarf_set_frame_same_value(),
+dwarf_set_frame_undefined_value(), and
+dwarf_set_frame_rule_initial_value() 
+is more flexible
+and will work for many more architectures.
+It is also entirely suitable for use with DWARF2 and DWARF4.
+The setting of  the 'frame cfa column number' 
+defaults to DW_FRAME_CFA_COL3
+and it can be set at runtime with dwarf_set_frame_cfa_value().
+.P
+Mixing use of the DWARF2 interface set with use
+of the new DWARF3 interface set
+on a single open Dwarf_Debug instance is a mistake.
+Do not do it.
+.P
+We will pretend, from here on unless otherwise
+specified, that 
+DW_FRAME_CFA_COL3, DW_FRAME_UNDEFINED_VAL,
+and DW_FRAME_SAME_VAL are the synthetic column numbers.
+These columns may be user-chosen by calls of
+dwarf_set_frame_cfa_value()
+dwarf_set_frame_undefined_value(), and
+dwarf_set_frame_same_value() respectively.
+
+.P
+Each cell in the table contains one of the following:
+
+.AL 
+.LI
+A register + offset(a)(b)
+
+.LI
+A register(c)(d)
+
+
+.LI
+A marker (DW_FRAME_UNDEFINED_VAL) meaning \fIregister value undefined\fP
+
+.LI
+A marker (DW_FRAME_SAME_VAL) meaning 
+\fIregister value same as in caller\fP
+.LE
+.P
+(a old DWARF2 interface) When  the column is DW_FRAME_CFA_COL: 
+the register
+number is a real hardware register, not a reference
+to DW_FRAME_CFA_COL, not  DW_FRAME_UNDEFINED_VAL,
+and not DW_FRAME_SAME_VAL. 
+The CFA rule value should be the stack pointer
+plus offset 0 when no other value makes sense.
+A value of DW_FRAME_SAME_VAL would
+be semi-logical, but since the CFA is not a real register,
+not really correct.
+A value of DW_FRAME_UNDEFINED_VAL would imply
+the CFA is undefined  --
+this seems to be a useless notion, as
+the CFA is a means to finding real registers,
+so those real registers should be marked DW_FRAME_UNDEFINED_VAL,
+and the CFA column content (whatever register it
+specifies) becomes unreferenced by anything.
+.P
+(a new April 2006 DWARF2/3 interface): The CFA is
+separately accessible and not part of the table.
+The 'rule number' for the CFA is a number outside the table. 
+So the CFA is a marker, not a register number.
+See  DW_FRAME_CFA_COL3 in libdwarf.h and
+dwarf_get_fde_info_for_cfa_reg3() and
+dwarf_set_frame_rule_cfa_value().
+.P
+(b) When the column is not DW_FRAME_CFA_COL3, the 'register'
+will and must be DW_FRAME_CFA_COL3(COL), implying that
+to get the final location for the column one must add
+the offset here plus the DW_FRAME_CFA_COL3 rule value.
+.P
+(c) When the column is DW_FRAME_CFA_COL3, then the 'register'
+number is (must be) a real hardware register .
+(This paragraph does not apply to the April 2006 new interface).
+If it were DW_FRAME_UNDEFINED_VAL or DW_FRAME_SAME_VAL
+it would be a marker, not a register number.
+.P
+(d) When the column is not DW_FRAME_CFA_COL3, the register
+may be a hardware register.
+It will not be DW_FRAME_CFA_COL3.
+.P
+There is no 'column' for DW_FRAME_UNDEFINED_VAL or DW_FRAME_SAME_VAL.
+Nor for DW_FRAME_CFA_COL3.

+The
+\f(CWdie\fP argument should be the value of 
+a \f(CWDwarf_Die\fP pointer of a \f(CWDwarf_Die\fP with

+has its own address_size field this argument is necessary to
+to correctly read ranges. (Most executables have the

+some ABIs allow multiple address sized in an executable).
+If a NULL pointer is passed in libdwarf assumes
+a single address_size is appropriate for all ranges records.

+The call sets
+\f(CW*ranges\fP to point to a block of \f(CWDwarf_Ranges\fP

+The choice of 'unsigned' for the value type argument (the code value)

+.DE
+The harmless errors are not denoted by error returns from
+the other libdwarf functions.  Instead, this function
+returns strings of any harmless errors that have been
+seen in the current object.  Clients never need call this, but
+if a client wishes to report any such errors it may call.
+
+Only a fixed number of harmless errors are recorded. It
+is a circular list, so if more than the current maximum
+is encountered older harmless error messages are lost.
+
+The caller passes in a pointer to an array of pointer-to-char 
+as the argument \f(CWerrmsg_ptrs_array\fP.  The caller
+must provide this array, libdwarf does not provide it.
+The caller need not initialize the array elements.
+
+The caller passes in the number of elements of the array of
+pointer-to-char thru \f(CWcount\fP.   Since the
+
+If there are no unreported harmless errors the function
+returns \f(CWDW_DLV_NO_ENTRY\fP and the function arguments
+are ignored.
+Otherwise the function returns \f(CWDW_DLV_OK\fP
+and uses the arguments.
+
+\f(CWlibdwarf\fP assigns error strings to the errmsg_ptrs_array.
+The MININUM(count-1, number of messages recorded) pointers are assigned
+to the array.  The array is terminated with a NULL pointer.
+(That is, one array entry is reserved for a NULL pointer).
+So if \f(CWcount\fP is 5 up to 4 strings may be returned through
+the array, and one array entry is set to NULL.
+
+Because the list is circular and messages may have been dropped
+the function also returns the actual error count of harmless
+errors encountered through \f(CWnewerr_count\fP
+(unless the argument is NULL, in which case it is ignored).
+
+Each call to this function resets the circular error buffer and
+the error count.   
+So think of this call as reporting harmless errors since the
+last call to it.
+
+The pointers returned through \f(CWerrmsg_ptrs_array\fP
+are only valid till the next call to libdwarf.  
+Do not save the pointers, they become invalid.  Copy the strings
+if you wish to save them.
+
+Calling this function neither allocates any space in memory nor
+frees any space in memory.

+This function is used to test 
+\f(CWdwarf_get_harmless_error_list\fP. It simply adds
+a harmless error string.  
+There is little reason client code should use this function.
+It exists so that the harmless error functions can be

+set to hold. 
+If \f(CWmaxcount\fP is non-zero the library changes the
+maximum it will record to be \f(CWmaxcount\fP.

+.H 1 "INTRODUCTION"
+This document describes an interface to \f(CWlibdwarf\fP, a
+library of functions to provide creation of DWARF debugging information
+records, DWARF line number information, DWARF address range and
+pubnames information, weak names information, and DWARF frame description 
+information.
+
+
+.H 2 "Copyright"
+Copyright 1993-2006 Silicon Graphics, Inc.
+
+Copyright 2007-2010 David Anderson.
+
+Permission is hereby granted to
+copy or republish or use any or all of this document without
+restriction except that when publishing more than a small amount
+of the document
+please acknowledge Silicon Graphics, Inc and David Anderson.
+
+This document is distributed in the hope that it would be useful, but
+WITHOUT ANY WARRANTY; without even the implied warranty of
+MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
+.H 2 "Purpose and Scope"
+The purpose of this document is to propose a library of functions to 
+create DWARF debugging information.  Reading (consuming) of such records 
+is discussed in a separate document.
+
+The functions in this document have mostly been implemented at 
+Silicon Graphics
+and are being used by the code generator to provide debugging information.
+Some functions (and support for some extensions) were provided
+by Sun Microsystems.
+
+Example code showing one use of the functionality
+may be found in the dwarfgen \f(CWdwarfgen\fP application
+(provided in the source distribution along with libdwarf).
+
+.P
+The focus of this document is the functional interface,
+and as such, implementation and optimization issues are
+intentionally ignored.
+
+.P
+Error handling, error codes, and certain \f(CWLibdwarf\fP codes are discussed
+in the "\fIA Consumer Library Interface to DWARF\fP", which should 
+be read (or at least skimmed) before reading this document.
+.P
+However the general style of functions here 
+in the producer library is rather C-traditional
+with various types as return values (quite different
+from the consumer library interfaces).   The style
+generally follows the style of the original DWARF1 reader
+proposed as an interface to DWARF.
+When the style of the reader interfaces was changed (1994) in the
+dwarf reader ( See the "Document History"
+section of "A Consumer Library Interface to DWARF")
+the interfaces here were not changed as it seemed like
+too much of a change for the two applications then using
+the interface!  So this interface remains in the traditional C style
+of returning various data types with various (somewhat inconsistent)
+means of indicating failure.
+.P
+The error handling code in the library may either
+return a value or abort. 
+The library user can provide a function that the producer code
+will call on errors (which would allow callers avoid testing
+for error returns if the user function exits or aborts).
+See the  \f(CWdwarf_producer_init_c()\fP
+description below for more details
+(possibly the older forms \f(CWdwarf_producer_init_b()\fP
+and \f(CWdwarf_producer_init()\fP may be of interest).
+
+
+.H 2 "Document History"
+This document originally prominently referenced
+"UNIX International Programming Languages Special Interest Group " 
+(PLSIG).
+Both  UNIX International and the
+affiliated  Programming Languages Special Interest Group
+are defunct
+(UNIX is a registered trademark of UNIX System Laboratories, Inc.
+in the United States and other countries).
+Nothing except the general interface style is actually
+related to anything shown to the PLSIG
+(this document was open sourced with libdwarf in the mid 1990's).
+.P
+See "http://www.dwarfstd.org" for information on current
+DWARF standards and committee activities.
+
+.H 2 "Definitions"
+DWARF debugging information entries (DIEs) are the segments of information 
+placed in the \f(CW.debug_info\fP  and related
+sections by compilers, assemblers, and linkage 
+editors that, in conjunction with line number entries, are necessary for 
+symbolic source-level debugging.  
+Refer to the document 
+"\fIDWARF Debugging Information Format\fP" from UI PLSIG for a more complete 
+description of these entries.
+
+.P
+This document adopts all the terms and definitions in
+"\fIDWARF Debugging Information Format\fP" version 2.
+and the "\fIA Consumer Library Interface to DWARF\fP".
+
+.P
+In addition, this document refers to Elf, the ATT/USL System V
+Release 4 object format.
+This is because the library was first developed for that object
+format.
+Hopefully the functions defined here can easily be
+applied to other object formats.
+
+.H 2 "Overview"
+The remaining sections of this document describe a proposed producer 
+(compiler or assembler) interface to \fILibdwarf\fP, first by describing 
+the purpose of additional types defined by the interface, followed by 
+descriptions of the available operations.  
+This document assumes you 
+are thoroughly familiar with the information contained in the 
+\fIDWARF 
+Debugging Information Format\fP document, and 
+"\fIA Consumer Library Interface to DWARF\fP".
+
+.P
+The interface necessarily knows a little bit about the object format
+(which is assumed to be Elf).  We make an attempt to make this knowledge 
+as limited as possible.  For example, \fILibdwarf\fP does not do the 
+writing of object data to the disk.  The producer program does that.
+
+.H 2 "Revision History"
+.VL 15
+.LI "March 1993"
+Work on dwarf2 sgi producer draft begins
+.LI "March 1999"
+Adding a function to allow any number of trips
+through the dwarf_get_section_bytes() call.
+.LI "April 10 1999"
+Added support for assembler text output of dwarf
+(as when the output must pass through an assembler).
+Revamped internals for better performance and
+simpler provision for differences in ABI.
+.LI "Sep 1, 1999"
+Added support for little- and cross- endian
+debug info creation.
+.LI "May 7  2007"
+This library interface now cleans up, deallocating
+all memory it uses (the application simply calls
+dwarf_producer_finish(dbg)).
+.LI "September 20  2010"
+Now documents the marker feature of DIE creation.
+.LE
+
+.H 1 "Type Definitions"
+
+.H 2 "General Description"
+The \fIlibdwarf.h\fP 
+header file contains typedefs and preprocessor 
+definitions of types and symbolic names 
+used to reference objects of \fI Libdwarf \fP .  
+The types defined by typedefs contained in \fI libdwarf.h\fP 
+all use the convention of adding \fI Dwarf_ \fP 
+as a prefix to
+indicate that they refer to objects used by Libdwarf.  
+The prefix \fI Dwarf_P_\fP is used for objects 
+referenced by the \fI Libdwarf\fP 
+Producer when there are similar but distinct 
+objects used by the Consumer.
+
+.H 2 "Namespace issues"
+Application programs should avoid creating names
+beginning with 
+\f(CWDwarf_\fP
+\f(CWdwarf_\fP
+or 
+\f(CWDW_\fP
+as these are reserved to dwarf and libdwarf.

+Much of the description below presumes that Elf is the object
+format in use.
+The library is probably usable with other object formats
+that allow arbitrary sections to be created.
+
+.H 2 "binary or assembler output"
+With 
+\f(CWDW_DLC_STREAM_RELOCATIONS\fP 
+(see below)
+it is assumed that the calling app will simply
+write the streams and relocations directly into
+an Elf file, without going through an assembler.
+
+With 
+\f(CWDW_DLC_SYMBOLIC_RELOCATIONS\fP 
+the calling app must either 
+A) generate binary relocation streams and write
+the generated debug information streams and
+the relocation streams direct to an elf file
+or
+B) generate assembler output text for an assembler
+to read and produce an object file. 
+
+With case B) the libdwarf-calling application must
+use the relocation information to change
+points of each binary stream into references to 
+symbolic names.  
+It is necessary for the assembler to be
+willing to accept and generate relocations
+for references from arbitrary byte boundaries.
+For example:
+.sp
+.nf
+.in +4
+ .data 0a0bcc    #producing 3 bytes of data.
+ .word mylabel   #producing a reference
+ .word endlabel - startlable #producing absolute length
+.in -4
+.fi
+.sp
+
+
+
+
+.H 2 "libdwarf relationship to Elf"
+When the documentation below refers to 'an elf section number'
+it is really only dependent on getting (via the callback
+function passed by the caller of
+\f(CWdwarf_producer_init_c()\fP and
+the older forms, \f(CWdwarf_producer_init_b()\fP or
+\f(CWdwarf_producer_init()\fP)
+a sequence of integers back (with 1 as the lowest).
+
+When the documentation below refers to 'an Elf symbol index'
+it is really dependent on 
+Elf symbol numbers
+only if
+\f(CWDW_DLC_STREAM_RELOCATIONS\fP 
+are being generated (see below).
+With 
+\f(CWDW_DLC_STREAM_RELOCATIONS\fP 
+the library is generating Elf relocations
+and the section numbers in binary form so
+the section numbers and symbol indices must really 
+be Elf (or elf-like) numbers.
+
+
+With
+\f(CWDW_DLC_SYMBOLIC_RELOCATIONS\fP 
+the values passed as symbol indexes can be any
+integer set or even pointer set.
+All that libdwarf assumes is that where values
+are unique they get unique values.
+Libdwarf does not generate any kind of symbol table
+from the numbers and does not check their
+uniqueness or lack thereof.
+
+.H 2 "libdwarf and relocations"
+With
+\f(CWDW_DLC_SYMBOLIC_RELOCATIONS\fP 
+libdwarf creates binary streams of debug information
+and arrays of relocation information describing
+the necessary relocation.
+The Elf section numbers and symbol numbers appear
+nowhere in the binary streams. Such appear
+only in the relocation information and the passed-back
+information from calls requesting the relocation information.
+As a consequence, the 'symbol indices' can be
+any pointer or integer value as the caller must
+arrange that the output deal with relocations.
+
+With 
+\f(CWDW_DLC_STREAM_RELOCATIONS\fP 
+all the relocations are directly created by libdwarf
+as binary streams (libdwarf only creates the streams
+in memory,
+it does not write them to disk).
+
+.H 2 "symbols, addresses, and offsets"
+The following applies to calls that
+pass in symbol indices, addresses, and offsets, such
+as
+\f(CWdwarf_add_AT_targ_address() \fP 
+\f(CWdwarf_add_arange_b()\fP 
+and
+\f(CWdwarf_add_frame_fde_b()\fP.
+
+With 
+\f(CWDW_DLC_STREAM_RELOCATIONS\fP 
+a passed in address is one of:
+a) a section offset and the (non-global) symbol index of
+a section symbol.
+b) A symbol index (global symbol) and a zero offset.
+
+With \f(CWDW_DLC_SYMBOLIC_RELOCATIONS\fP
+the same approach can be used, or, instead,
+a passed in address may be
+c) a symbol handle and an offset.
+In this case, since it is up to the calling app to
+generate binary relocations (if appropriate)
+or to turn the binary stream into 
+a text stream (for input to an assembler, if appropriate)
+the application has complete control of the interpretation
+of the symbol handles.
+
+
+
+.H 1 "Memory Management"
+
+Several of the functions that comprise the \fILibdwarf\fP 
+producer interface dynamically allocate values and some
+return pointers to those spaces.
+The dynamically allocated spaces 
+can not be reclaimed  (and must
+not be freed)  except by \f(CWdwarf_producer_finish(dbg)\fP.  
+
+All data for a particular \f(CWDwarf_P_Debug\fP descriptor
+is separate from the data for any other 
+\f(CWDwarf_P_Debug\fP descriptor in use in the library-calling
+application.
+
+.H 2 "Read-only Properties"
+All pointers returned by or as a result of a \fILibdwarf\fP call should 
+be assumed to point to read-only memory.  
+Except as defined by this document, the results are undefined for 
+\fILibdwarf\fP clients that attempt to write to a region pointed to by a 
+return value from a \fILibdwarf\fP call.
+
+.H 2 "Storage Deallocation"
+Calling \f(CWdwarf_producer_finish(dbg)\fP frees all the space, and 
+invalidates all pointers returned from \f(CWLibdwarf\fP functions on 
+or descended from \f(CWdbg\fP).
+
+.H 1 "Functional Interface"
+This section describes the functions available in the \fILibdwarf\fP
+library.  Each function description includes its definition, followed 
+by a paragraph describing the function's operation.
+
+.P
+The functions may be categorized into groups: 
+\fIinitialization and termination operations\fP,
+\fIdebugging information entry creation\fP,
+\fIElf section callback function\fP,
+\fIattribute creation\fP,
+\fIexpression creation\fP, 
+\fIline number creation\fP, 
+\fIfast-access (aranges) creation\fP, 
+\fIfast-access (pubnames) creation\fP, 
+\fIfast-access (weak names) creation\fP,
+\fImacro information creation\fP, 
+\fIlow level (.debug_frame) creation\fP, 
+and
+\fIlocation list (.debug_loc) creation\fP. 
+
+.P
+The following sections describe these functions.
+
+.H 2 "Initialization and Termination Operations"
+These functions setup \f(CWLibdwarf\fP to accumulate debugging information
+for an object, usually a compilation-unit, provided by the producer.
+The actual addition of information is done by functions in the other
+sections of this document.  Once all the information has been added,
+functions from this section are used to transform the information to
+appropriate byte streams, and help to write out the byte streams to
+disk.
+
+Typically then, a producer application 
+would create a \f(CWDwarf_P_Debug\fP 
+descriptor to gather debugging information for a particular
+compilation-unit using \f(CWdwarf_producer_init_c()\fP.  
+(Older code may use \f(CWdwarf_producer_init_b()\fP or
+\f(CWdwarf_producer_init()\fP).
+The producer application would 
+use this \f(CWDwarf_P_Debug\fP descriptor to accumulate debugging 
+information for this object using functions from other sections of 
+this document.  
+Once all the information had been added, it would 
+call \f(CWdwarf_transform_to_disk_form()\fP to convert the accumulated 
+information into byte streams in accordance with the \f(CWDWARF\fP 
+standard.  
+The application would then repeatedly call 
+\f(CWdwarf_get_section_bytes()\fP 
+for each of the \f(CW.debug_*\fP created.  
+This gives the producer 
+information about the data bytes to be written to disk.  
+At this point, 
+the producer would release all resource used by \f(CWLibdwarf\fP for 
+this object by calling \f(CWdwarf_producer_finish()\fP.
+
+It is also possible to create assembler-input character streams
+from the byte streams created by this library.
+This feature requires slightly different interfaces than
+direct binary output.
+The details are mentioned in the text.

+.DE
+This is the oldest form and code should migrate to the newest form,
+\f(CWdwarf_producer_init_c()\fP.
+.P
+The function \f(CWdwarf_producer_init() \fP returns a new 
+\f(CWDwarf_P_Debug\fP descriptor that can be used to add \f(CWDwarf\fP 
+information to the object.  
+On error it returns \f(CWDW_DLV_BADADDR\fP.  
+\f(CWflags\fP determine whether the target object is 64-bit or 32-bit.  
+\f(CWfunc\fP is a pointer to a function called-back from \f(CWLibdwarf\fP 
+whenever \f(CWLibdwarf\fP needs to create a new object section (as it will 
+for each .debug_* section and related relocation section).  
+.P
+\f(CWerrhand\fP 
+is a pointer to a function that will be used as
+a default fall-back function for handling errors detected 
+by \f(CWLibdwarf\fP.  
+.P
+\f(CWerrarg\fP is the default error argument used 
+by the function pointed to by \f(CWerrhand\fP.
+.P
+For historical reasons the error handling is complicated
+and the following three paragraphs describe the  three
+possible scenarios when a producer function detects an error.
+In all cases a short error message is printed on
+stdout if the error number
+is negative (as all such should be, see libdwarf.h).
+Then further action is taken as follows.
+.P
+First,
+if the  Dwarf_Error argument to any specific producer function
+(see the functions documented below)  is non-null
+the \f(CWerrhand\fP argument here is ignored in that call and
+the specific producer function sets the Dwarf_Error and returns
+some specific value (for dwarf_producer_init it is DW_DLV_BADADDR
+as mentioned just above) indicating there is an error.
+.P
+Second,
+if the  Dwarf_Error argument to any specific producer function 
+(see the functions documented below)  is NULL and the
+\f(CWerrarg\fP  to \f(CWdwarf_producer_init() \fP is non-NULL
+then on an error in the producer code the Dwarf_Handler function is called
+and if that called function returns the producer code returns
+a specific value (for dwarf_producer_init it is DW_DLV_BADADDR
+as mentioned just above) indicating there is an error.
+.P
+Third,
+if the  Dwarf_Error argument to any specific producer function
+(see the functions documented below)  is NULL and the
+\f(CWerrarg\fP  to \f(CWdwarf_producer_init() \fP is NULL
+then on an error \f(CWabort()\fP is called.
+.P
+The \f(CWflags\fP
+values are as follows:

+may be used (see next paragraph) to generate DWARF (if and only if
+DW_DLC_SIZE_64 is also ORed into \f(CWflags\fP).
+
+If \f(CWHAVE_STRICT_32BIT_OFFSET\fP is set at configure time

+The \f(CWDwarf_Rel_Type\fP enum is encoded (via casts if necessary)

+The unsigned char \f(CWdrd_length\fP field

+will be 4.  For objects with MIPS -64 contents,
+\f(CWdrd_length\fP will be 8.  
+For some dwarf 64 bit environments, such as ia64, \f(CWdrd_length\fP

+\f(CWdrd_length\fP gives the length of the field to be relocated.
+\f(CWdrd_offset\fP is an offset (of the

+MIPS Extensions to DWARF Version 2.0
+.AF ""
+.AU "Silicon Graphics Computer Systems"
+.PF "'\*(vE'- \\\\nP -''"
+.AS 1
+This document describes the MIPS/Silicon Graphics extensions 
+to the "DWARF Information Format" (version 2.0.0 dated July 27, 1993).
+DWARF3 draft 8 (or draft 9) is out as of 2005, and
+is mentioned below where applicable.
+MIPS/IRIX compilers emit DWARF2 (with extensions).
+.P
+Rather than alter the base documents to describe the extensions
+we provide this separate document.
+.P
+The extensions documented here are subject to change.
+.P
+It also describes known bugs resulting in incorrect dwarf usage.
+.P
+\*(vE

+
+.H 1 "INTRODUCTION"
+.P
+This 
+document describes MIPS extensions 
+to the DWARF debugging information format.  
+The extensions documented here are subject to change at
+any time.
+.H 1 "64 BIT DWARF"
+.P
+The DWARF2 spec has no provision for 64 bit offsets.
+SGI-IRIX/MIPS Elf64 objects contain DWARF 2 with all offsets
+(and addresses) as 64bit values.  
+This non-standard extension was adopted in 1992.
+Nothing in the dwarf itself identifies the dwarf as 64bit.
+This extension 64bit-offset dwarf cannot be mixed with 32bit-offset dwarf
+in a single object or executable, and SGI-IRIX/MIPS compilers
+and tools do not mix the sizes.
+.P
+In 2001 DWARF3 adopted a very different 64bit-offset
+format which can be mixed usefully with 32bit-offset DWARF2 or DWARF3.
+It is not very likely SGI-IRIX/MIPS compilers will switch to the 
+now-standard
+DWARF3 64bit-offset scheme, but such a switch is theoretically
+possible and would be a good idea.
+.P
+SGI-IRIX/MIPS Elf32 objects
+contain DWARF2 with all offsets (and addresses) 32 bits.
+.H 1 "How much symbol information is emitted"
+The following standard DWARF V2 sections may be emitted:
+.AL
+.LI 
+Section .debug_abbrev
+contains
+abbreviations supporting the .debug_info section.
+.LI
+Section .debug_info
+contains
+Debug Information Entries (DIEs).
+.LI 
+Section .debug_frame
+contains
+stack frame descriptions.
+.LI 
+Section .debug_line
+contains
+line number information.
+.LI 
+Section .debug_aranges
+contains
+address range descriptions.
+.LI 
+Section .debug_pubnames
+contains
+names of global functions and data.
+.P
+The following
+are MIPS extensions.
+Theses were created to allow debuggers to
+know names without having to look at
+the .debug_info section.
+.LI 
+Section .debug_weaknames
+is a MIPS extension
+containing .debug_pubnames-like entries describing weak
+symbols.
+.LI 
+Section .debug_funcnames
+is a MIPS extension
+containing .debug_pubnames-like entries describing file-static
+functions (C static functions).
+The gcc extension of nested subprograms (like Pascal)
+adds non-global non-static functions.  These should be treated like
+static functions and gcc should add such to this section
+so that IRIX libexc(3C) will work correctly.
+Similarly, Ada functions which are non-global should be here too
+so that libexc(3C) can work.
+Putting it another way, every function (other than inline code)
+belongs either in .debug_pubnames or in .debug_funcnames
+or else libexc(3C) cannot find the function name.
+.LI 
+Section .debug_varnames
+is a MIPS extension
+containing .debug_pubnames-like entries describing file-static
+data symbols (C static variables).
+.LI 
+Section .debug_typenames
+is a MIPS extension
+containing .debug_pubnames-like entries describing file-level
+types.
+.P
+The following are not currently emitted.
+.LI 
+Section .debug_macinfo
+Macro information is not currently emitted.
+.LI 
+Section .debug_loc
+Location lists are not currently emitted.
+.LI
+Section .debug_str
+The string section is not currently emitted.
+.LE
+.H 2 "Overview of information emitted"
+We emit debug information in 3 flavors.
+We mention C here.
+The situation is essentially identical for f77, f90, and C++.
+.AL
+.LI 
+"default C"
+We emit line information and DIEs for each subprogram.
+But no local symbols and no type information.
+Frame information is output.
+The DW_AT_producer string has the optimization level: for example
+"-O2".
+We put so much in the DW_AT_producer that the string
+is a significant user of space in .debug_info --
+this is perhaps a poor use of space.
+When optimizing the IRIX CC/cc option -DEBUG:optimize_space
+eliminates such wasted space.
+Debuggers only currently use the lack of -g
+of DW_AT_producer
+as a hint as to how a 'step' command should be interpreted, and
+the rest of the string is not used for anything (unless
+a human looks at it for some reason), so if space-on-disk
+is an issue, it is quite appropriate to use -DEBUG:optimize_space
+and save disk space.
+Every function definition (not inline instances though) is mentioned
+in either .debug_pubnames or .debug_funcnames.
+This is crucial to allow libexc(3C) stack-traceback to work and
+show function names (for all languages).
+.LI 
+"C with full symbols"
+All possible info is emitted.
+DW_AT_producer string has all options that might be of interest,
+which includes -D's, -U's, and the -g option.
+These options look like they came from the command line.
+We put so much in the DW_AT_producer that the string
+is a significant user of space in .debug_info.
+this is perhaps a poor use of space.
+Debuggers only currently use the -g
+of DW_AT_producer
+as a hint as to how a 'step' command should be interpreted, and
+the rest of the string is not used for anything (unless
+a human looks at it for some reason).
+Every function definition (not inline instances though) is mentioned
+in either .debug_pubnames or .debug_funcnames.
+This is crucial to allow libexc(3C) stack-traceback to work and
+show function names (for all languages).
+.LI 
+"Assembler (-g, non -g are the same)"
+Frame information is output.
+No type information is emitted, but DIEs are prepared
+for globals.
+.LE
+.H 2 "Detecting 'full symbols' (-g)"
+The debugger depends on the existence of
+the DW_AT_producer string to determine if the
+compilation unit has full symbols or not.
+It looks for -g or -g[123] and accepts these as
+full symbols but an absent -g or a present -g0 
+is taken to mean that only basic symbols are defined and there
+are no local symbols and no type information.
+.P
+In various contexts the debugger will think the program  is
+stripped or 'was not compiled with -g' unless the -g
+is in the DW_AT_producer string.
+.H 2 "DWARF and strip(1)"
+The DWARF section ".debug_frame" is marked SHF_MIPS_NOSTRIP
+and is not stripped by the strip(1) program.
+This is because the section is needed for doing
+stack back traces (essential for C++
+and Ada exception handling).
+.P
+All .debug_* sections are marked with elf type
+SHT_MIPS_DWARF.
+Applications needing to access the various DWARF sections
+must use the section name to discriminate between them. 
+
+.H 2 "Evaluating location expressions"
+When the debugger evaluates location expressions, it does so
+in 2 stages. In stage one it simply looks for the trivial
+location expressions and treats those as special cases.
+.P
+If the location expression is not trivial, it enters stage two.
+In this case it uses a stack to evaluate the expression.
+.P
+If the application is a 32-bit application, it does the operations
+on 32-bit values (address size values).  Even though registers
+can be 64 bits in a 32-bit program all evaluations are done in 
+32-bit quantities, so an attempt to calculate a 32-bit quantity
+by taking the difference of 2 64-bit register values will not
+work.  The notion is that the stack machine is, by the dwarf
+definition, working in address size units.
+.P
+These values are then expanded to 64-bit values (addresses or
+offsets).   This extension does not involve sign-extension.
+.P
+If the application is a 64-bit application, then the stack
+values are all 64 bits and all operations are done on 64 bits.
+.H 3 "The fbreg location op"
+Compilers shipped with IRIX 6.0 and 6.1
+do not emit the fbreg location expression
+and never emit the DW_AT_frame_base attribute that it
+depends on. 
+However, this changes
+with release 6.2 and these are now emitted routinely.
+
+.H 1 "Frame Information"
+.H 2 "Initial Instructions"
+The DWARF V2 spec 
+provides for "initial instructions" in each CIE (page 61,
+section 6.4.1).
+However, it does not say whether there are default
+values for each column (register).
+.P
+Rather than force every CIE to have a long list
+of bytes to initialize all 32 integer registers,
+we define that the default values of all registers
+(as returned by libdwarf in the frame interface)
+are 'same value'.
+This is a good choice for many non-register-windows
+implementations.
+.H 2 "Augmentation string in debug_frame"
+The augmentation string we use in shipped compilers (up thru
+irix6.2) is the empty string.
+IRIX6.2 and later has an augmentation string 
+the empty string ("")
+or "z" or "mti v1" 
+where the "v1" is a version number (version 1).
+.P
+We do not believe that "mti v1" was emitted  as the
+augmentation string in any shipped compiler.
+.P
+.H 3 "CIE processing based on augmentation string:"
+If the augmentation string begins with 'z', then it is followed
+immediately by a unsigned_leb_128 number giving the code alignment factor.
+Next is a signed_leb_128 number giving the data alignment factor.
+Next is a unsigned byte giving the number of the return address register.
+Next is an unsigned_leb_128 number giving the length of the 'augmentation'
+fields  (the length of augmentation bytes, not
+including the unsigned_leb_128 length itself).
+As of release 6.2, the length of the CIE augmentation fields is 0.
+What this means is that it is possible to add new
+augmentations, z1, z2, etc and yet an old consumer to
+understand the entire CIE as it can bypass the
+augmentation it does not understand because the
+length of the augmentation fields is present.
+Presuming of course that all augmentation fields are
+simply additional information, 
+not some 'changing of the meaning of 
+an existing field'.
+Currently there is no CIE data in the augmentation for things
+beginning with 'z'.
+.P
+If the augmentation string is "mti v1" or "" then it is followed
+immediately by a unsigned_leb_128 number giving the code alignment factor.
+Next is a signed_leb_128 number giving the data alignment factor.
+Next is a unsigned byte giving the number of the return address register.
+.P
+If the augmentation string is something else, then the
+code alignment factor is assumed to be 4 and the data alignment
+factor is assumed to be -1 and the return
+address register is assumed to be 31. Arbitrarily.
+The library (libdwarf) assumes it does not understand the rest of the CIE.
+.P
+.H 3 "FDE processing based on augmentation"
+If the CIE augmentation string 
+for an fde begins with 'z'
+then the next FDE field after the address_range field
+is an 
+unsigned_leb_128 number giving the length of the 'augmentation'
+fields, and those fields follow immediately.
+
+.H 4 "FDE augmentation fields"
+.P
+If the CIE augmentation string is "mti v1" or ""
+then the FDE is exactly as described in the Dwarf Document section 6.4.1.
+.P
+Else, if the CIE augmentation string begins with "z"
+then the next field after the FDE augmentation length field
+is a Dwarf_Sword size offset into
+exception tables.
+If the CIE augmentation string does not begin with "z"
+(and is neither "mti v1" nor "")
+the FDE augmentation fields are skipped (not understood).
+Note that libdwarf actually (as of MIPSpro7.3 and earlier)
+only tests that the initial character of the augmentation
+string is 'z', and ignores the rest of the string, if any.
+So in reality the test is for a _prefix_ of 'z'.
+.P
+If the CIE augmentation string neither starts with 'z' nor is ""
+nor is "mti v1" then libdwarf (incorrectly) assumes that the
+table defining instructions start next.  
+Processing (in libdwarf) will be incorrect.
+.H 2 "Stack Pointer recovery from debug_frame"
+There is no identifiable means in
+DWARF2 to say that the stack register is
+recovered by any particular operation.
+A 'register rule' works if the caller's
+stack pointer was copied to another
+register.
+An 'offset(N)' rule works if the caller's
+stack pointer was stored on the stack.
+However if the stack pointer is
+some register value plus/minus some offset,
+there is no means to say this in an FDE.
+For MIPS/IRIX, the recovered stack pointer
+of the next frame up the stack (towards main())
+is simply the CFA value of the current
+frame, and the CFA value is
+precisely a register (value of a register)
+or a register plus offset (value of a register
+plus offset).  This is a software convention.
+.H 1 "egcs dwarf extensions (egcs-1.1.2 extensions)"
+This and following egcs sections describe
+the extensions currently shown in egcs dwarf2.
+Note that egcs has chosen to adopt tag and
+attribute naming as if their choices were
+standard dwarf, not as if they were extensions.
+However, they are properly numbered as extensions.
+
+.H 2 "DW_TAG_format_label             0x4101" 
+For FORTRAN 77, Fortran 90.
+Details of use not defined in egcs source, so
+unclear if used.
+.H 2 "DW_TAG_function_template        0x4102"
+For C++.
+Details of use not defined in egcs source, so
+unclear if used.
+.H 2 "DW_TAG_class_template           0x4103" 
+For C++.
+Details of use not defined in egcs source, so
+unclear if used.
+.H 2 "DW_AT_sf_names                          0x2101"
+Apparently only output in DWARF1, not DWARF2.
+.H 2 "DW_AT_src_info                          0x2102"
+Apparently only output in DWARF1, not DWARF2.
+.H 2 "DW_AT_mac_info                          0x2103"
+Apparently only output in DWARF1, not DWARF2.
+.H 2 "DW_AT_src_coords                        0x2104"
+Apparently only output in DWARF1, not DWARF2.
+.H 2 "DW_AT_body_begin                        0x2105"
+Apparently only output in DWARF1, not DWARF2.
+.H 2 "DW_AT_body_end                          0x2106"
+Apparently only output in DWARF1, not DWARF2.
+
+.H 1 "egcs .eh_frame (non-sgi) (egcs-1.1.2 extensions)"
+egcs-1.1.2 (and earlier egcs)
+emits by default a section named .eh_frame 
+for ia32 (and possibly other platforms) which
+is nearly identical to .debug_frame in format and content.
+This section is used for helping handle C++ exceptions.
+.P
+Because after linking there are sometimes zero-ed out bytes
+at the end of the eh_frame section, the reader code in
+dwarf_frame.c considers a zero cie/fde length as an indication
+that it is the end of the section.
+.P
+.H 2 "CIE_id 0"
+The section is an ALLOCATED section in an executable, and
+is therefore mapped into memory at run time.
+The CIE_pointer (aka CIE_id, section 6.4.1
+of the DWARF2 document) is the field that 
+distinguishes a CIE from an FDE.
+The designers of the egcs .eh_frame section
+decided to make the CIE_id
+be 0 as the CIE_pointer definition is
+.in +2
+the number of bytes from the CIE-pointer in the FDE back to the
+applicable CIE.
+.in -2
+In a dwarf .debug_frame section, the CIE_pointer is the
+offset in .debug_frame of the CIE for this fde, and
+since an offset can be zero of some CIE, the CIE_id
+cannot be 0, but must be all 1 bits .
+Note that the dwarf2.0 spec does specify the value of CIE_id
+as 0xffffffff
+(see section 7.23 of v2.0.0),
+though earlier versions of this extensions document
+incorrectly said it was not specified in the dwarf
+document.
+.H 2 "augmentation eh"
+The augmentation string in each CIE is "eh"
+which, with its following NUL character, aligns
+the following word to a 32bit boundary.
+Following the augmentation string is a 32bit
+word with the address of the __EXCEPTION_TABLE__,
+part of the exception handling data for egcs.
+.H 2 "DW_CFA_GNU_window_save   0x2d"
+This is effectively a flag for architectures with
+register windows, and tells the unwinder code that
+it must look to a previous frame for the
+correct register window set.
+As of this writing, egcs  gcc/frame.c
+indicates this is for SPARC register windows.
+.H 2 "DW_CFA_GNU_args_size     0x2e"
+DW_CFA_GNU_args_size has a single uleb128 argument
+which is the size, in bytes, of the function's stack
+at that point in the function.
+.H 2 "__EXCEPTION_TABLE__"
+A series of 3 32bit word entries by default:
+0 word: low pc address
+1 word: high pc address
+2 word: pointer to exception handler code
+The end of the table is 
+signaled by 2 words  of -1 (not 3 words!).
+.H 1 "Interpretations of the DWARF V2 spec"
+.H 2 "template TAG spellings"
+The DWARF V2 spec spells two attributes in two ways.
+DW_TAG_template_type_param 
+(listed in Figure 1, page 7)
+is spelled DW_TAG_template_type_parameter
+in the body of the document (section 3.3.7, page 28).
+We have adopted the spelling 
+DW_TAG_template_type_param.
+.P
+DW_TAG_template_value_param
+(listed in Figure 1, page 7)
+is spelled DW_TAG_template_value_parameter
+in the body of the document (section 3.3.7, page 28).
+We have adopted the spelling 
+DW_TAG_template_value_parameter.
+.P
+We recognize that the choices adopted are neither consistently
+the longer nor the shorter name.
+This inconsistency was an accident.
+.H 2 DW_FORM_ref_addr confusing
+Section 7.5.4, Attribute Encodings, describes
+DW_FORM_ref_addr.
+The description says the reference is the size of an address
+on the target architecture.
+This is surely a mistake, because on a 16bit-pointer-architecture
+it would mean that the reference could not exceed
+16 bits, which makes only
+a limited amount of  sense as the reference is from one
+part of the dwarf to another, and could (in theory)
+be *on the disk* and not limited to what fits in memory.
+Since MIPS is 32 bit pointers (at the smallest) 
+the restriction is not a problem for MIPS/SGI.
+The 32bit pointer ABIs are limited to 32 bit section sizes
+anyway (as a result of implementation details).
+And the 64bit pointer ABIs currently have the same limit
+as a result of how the compilers and tools are built
+(this has not proven to be a limit in practice, so far).
+.P
+This has been clarified in the DWARF3 spec and the IRIX use
+of DW_FORM_ref_addr being an offset is correct.
+.H 2 "Section .debug_macinfo in a debugger"
+It seems quite difficult, in general, to
+tie specific text(code) addresses to points in the
+stream of macro information for a particular compilation unit.
+So it's been difficult to see how to design a consumer
+interface to libdwarf for macro information.
+.P
+The best (simple to implement, easy for a debugger user to
+understand) candidate seems to be that
+the debugger asks for macros of a given name in a compilation
+unit, and the debugger responds with *all* the macros of that name.
+.H 3 "only a single choice exists"
+If there is exactly one, that is usable in expressions, if the
+debugger is able to evaluate such.
+.H 3 "multiple macros with same name".
+If there are multiple macros with the same name
+in a compilation unit, 
+the debugger (and the debugger user and the application
+programmer) have
+a problem: confusion is quite possible.
+If the macros are simple the
+debugger  user can simply substitute by hand in an expression.
+If the macros are complicated hand substitution will be
+impractical, and the debugger will have to identify the
+choices and let the debugger user choose an interpretation.
+.H 2 "Section 6.1.2 Lookup by address problem"
+Each entry is a beginning-address followed by a length.
+And the distinguished entry 0,0 is used to denote
+the end of a range of entries.
+.P
+This means that one must be careful not to emit a zero length,
+as in a .o (object file) the beginning address of
+a normal entry might be 0 (it is a section offset after all),
+and the resulting 0,0 would be taken as end-of-range, not
+as a valid entry.
+A dwarf dumper would have trouble with such data
+in an object file.
+.P
+In an a.out or shared object (dynamic shared object, DSO)
+no text will be at address zero so in such this problem does
+not arise.
+.H 2 "Section 5.10 Subrange Type Entries problem"
+It is specified that  DW_AT_upper_bound (and lower bound)
+must be signed entries if there is no object type
+info to specify the bound type (Sec 5.10, end of section). 
+One cannot tell (with some
+dwarf constant types) what the signedness is from the
+form itself (like DW_FORM_data1), so it is necessary
+to determine the object and type according to the rules 
+in 5.10 and then if all that fails, the type is signed.
+It's a bit complicated and earlier versions of  mips_extensions
+incorrectly said signedness was not defined.
+.H 2 "Section 5.5.6 Class Template Instantiations problem"
+Lots of room for implementor to canonicalize
+template declarations.  Ie various folks won't agree.
+This is not serious since a given compiler
+will be consistent with itself and  debuggers
+will have to cope!
+.H 2 "Section 2.4.3.4  # 11. operator spelling"  
+DW_OP_add should be DW_OP_plus (page 14)
+(this mistake just one place on the page).
+.H 2 "No clear specification of C++ static funcs"
+There is no clear way to tell if a C++ member function
+is a static member or a non-static member function.
+(dwarf2read.c in gdb 4.18, for example, has this observation)
+.H 2 "Misspelling of DW_AT_const_value"
+Twice in appendix 1, DW_AT_const_value is misspelled
+as DW_AT_constant_value.
+.H 2 "Mistake in Atribute Encodings"
+Section 7.5.4, "Attribute Encodings"
+has a brief discussion of "constant"
+which says there are 6 forms of constants.
+It is incorrect in that it fails to mention (or count)
+the block forms, which are clearly allowed by
+section 4.1 "Data Object Entries" (see entry number 9 in
+the numbered list, on constants).
+.H 2 "DW_OP_bregx"
+The description of DW_OP_bregx in 2.4.3.2 (Register Based
+Addressing) is slightly misleading, in that it
+lists the offset first.
+As section 7.7.1 (Location Expression)
+makes clear, in the encoding the register number
+comes first.
+.H 1 "MIPS attributes"
+.H 2 "DW_AT_MIPS_fde"
+This extension to Dwarf appears only on subprogram TAGs and has as
+its value the offset, in the .debug_frame section, of the fde which
+describes the frame of this function.  It is an optimization of
+sorts to have this present.
+
+.H 2 "DW_CFA_MIPS_advance_loc8 0x1d"
+This obvious extension to dwarf line tables enables encoding of 8 byte
+advance_loc values (for cases when such must be relocatable, 
+and thus must be full length).  Applicable only to 64-bit objects.
+
+.H 2 "DW_TAG_MIPS_loop        0x4081"
+For future use. Not currently emitted.

+.H 2 "DW_AT_MIPS_linkage_name                 0x2007"
+The rules for mangling C++ names are not part of the
+C++ standard and are different for different versions
+of C++.  With this extension, the compiler emits
+both the DW_AT_name for things with mangled names 
+(recall that DW_AT_name is NOT the mangled form)
+and also emits DW_AT_MIPS_linkage_name whose value
+is the mangled name.
+.P
+This makes looking for the mangled name in other linker
+information straightforward.
+It also is passed (by the debugger) to the
+libmangle routines to generate names to present to the
+debugger user.
+.H 2 "DW_AT_MIPS_stride            0x2008"
+F90 allows assumed shape arguments and pointers to describe
+non-contiguous memory. A (runtime) descriptor contains address,
+bounds and stride information - rank and element size is known
+during compilation. The extent in each dimension is given by the
+bounds in a DW_TAG_subrange_type, but the stride cannot be
+represented in conventional dwarf. DW_AT_MIPS_stride was added as
+an attribute of a DW_TAG_subrange_type to describe the
+location of the stride.
+Used in the MIPSpro 7.2 (7.2.1 etc) compilers.
+.P
+If the stride is constant (ie: can be inferred from the type in the
+usual manner) DW_AT_MIPS_stride is absent. 
+.P
+If DW_AT_MIPS_stride is present, the attribute contains a reference
+to a DIE which describes the location holding the stride, and the
+DW_AT_stride_size field of DW_TAG_array_type is ignored if
+present.  The value of the stride is the number of 
+4 byte words between
+elements along that axis.
+.P
+This applies to 
+.nf
+a) Intrinsic types whose size is greater 
+   or equal to 4bytes ie: real*4,integer*8 
+   complex etc, but not character types.
+
+b) Derived types (ie: structs) of any size, 
+   unless all components are of type character.
+.fi
+
+.H 2 "DW_AT_MIPS_abstract_name              0x2009"
+This attribute only appears in a DA_TAG_inlined_subroutine DIE.
+The value of this attribute is a string.
+When IPA inlines a routine and the abstract origin is
+in another compilation unit, there is a problem with putting
+in a reference, since the ordering and timing of the 
+creation of references is unpredicatable with reference to
+the DIE and compilation unit the reference refers to. 
+.P
+Since there may be NO ordering of the compilation units that
+allows a correct reference to be done without some kind of patching,
+and since even getting the information from one place to another
+is a problem, the compiler simply passes the problem on to the debugger.
+.P
+The debugger must match the DW_AT_MIPS_abstract_name 
+in the concrete
+inlined instance DIE 
+with the  DW_AT_MIPS_abstract_name
+in the abstract inlined subroutine DIE.
+.P
+A dwarf-consumer-centric view of this  and other inline
+issues could be expressed as follows:
+.nf
+If DW_TAG_subprogram
+  If has DW_AT_inline is abstract instance root
+  If has DW_AT_abstract_origin, is out-of-line instance
+    of function (need abstract origin for some data)
+    (abstract root in same CU (conceptually anywhere
+    a ref can reach, but reaching outside of CU is
+    a problem for ipa: see DW_AT_MIPS_abstract_name))
+  If has DW_AT_MIPS_abstract_name is abstract instance
+    root( must have DW_AT_inline) and this name is used to
+    match with the abstract root
+
+If DW_TAG_inline_subroutine
+  Is concrete inlined subprogram instance.
+  If has DW_AT_abstract_origin, it is a CU-local inline.
+  If it has DW_AT_MIPS_abstract_name it is an
+    inline whose abstract root is in another file (CU).
+.fi
+
+.H 2 "DW_AT_MIPS_clone_origin               0x200a"
+This attribute appears only in a cloned subroutine.
+The procedure is cloned from the same compilation unit.
+The value of this attribute is a reference to 
+the original routine in this compilation unit.
+.P
+The 'original' routine means the routine which has all the
+original code.  The cloned routines will always have
+been 'specialized' by IPA.   
+A routine with DW_AT_MIPS_clone_origin
+will also have the DW_CC_nocall value of the DW_AT_calling_convention
+attribute.
+
+.H 2 "DW_AT_MIPS_has_inlines               0x200b"
+This attribute  may appear in a DW_TAG_subprogram DIE.
+If present and it has the value True, then the subprogram
+has inlined functions somewhere in the body.
+.P
+By default, at startup, the debugger may not look for 
+inlined functions in scopes inside the outer function.
+.P
+This is a hint to the debugger to look for the inlined functions
+so the debugger can set breakpoints on these in case the user
+requests 'stop in foo' and foo is inlined.
+.H 2 "DW_AT_MIPS_stride_byte                  0x200c"
+Created for f90 pointer and assumed shape
+arrays.
+Used in the MIPSpro 7.2 (7.2.1 etc) compilers.
+A variant of DW_AT_MIPS_stride. 
+This stride is interpreted as a byte count. 
+Used for integer*1 and character arrays
+and arrays of derived type
+whose components are all character.
+.H 2 "DW_AT_MIPS_stride_elem                  0x200d"
+Created for f90 pointer and assumed shape
+arrays.
+Used in the MIPSpro 7.2 (7.2.1 etc) compilers.
+A variant of DW_AT_MIPS_stride. 
+This stride is interpreted as a byte-pair (2 byte) count.

+See following.
+.H 2 "DW_AT_MIPS_assumed_shape_dopetype       0x2010"
+DW_AT_MIPS_assumed_shape_dopetype, DW_AT_MIPS_allocatable_dopetype,
+and DW_AT_MIPS_ptr_dopetype have an attribute value
+which is a reference to a Fortran 90 Dope Vector.
+These attributes are introduced in MIPSpro7.3.
+They only apply to f90 arrays (where they are
+needed to describe arrays never properly described
+before in debug information).
+C, C++, f77, and most f90 arrays continue to be described
+in standard dwarf.
+.P
+The distinction between these three attributes is the f90 syntax
+distinction: keywords 'pointer' and 'allocatable' with the absence
+of these keywords on an assumed shape array being the third case.
+.P
+A "Dope Vector" is a struct (C struct) which describes
+a dynamically-allocatable array.
+In objects with full debugging the C struct will be
+in the dwarf information (of the f90 object, represented like C).
+A debugger will use the link to find the main struct DopeVector
+and will use that information to decode the dope vector.
+At the outer allocatable/assumed-shape/pointer
+the DW_AT_location points at the dope vector (so debugger
+calculations use that as a base).
+.H 2 "Overview of debugger use of dope vectors"
+Fundamentally, we build two distinct
+representations of the arrays and pointers.
+One, in dwarf, represents the statically-representable
+information (the types and
+variable/type-names, without type size information).
+The other, using dope vectors in memory, represents
+the run-time data of sizes.
+A debugger must process the two representations
+in parallel (and merge them) to deal with  user expressions in
+a debugger.
+.H 2 "Example f90 code for use in explanation"
+[Note
+We want dwarf output with *exactly* 
+this little (arbitrary) example.
+Not yet available.
+end Note]
+Consider the following code.
+.nf
+       type array_ptr
+	  real   :: myvar
+          real, dimension (:), pointer :: ap
+       end type array_ptr
+
+       type (array_ptr), allocatable, dimension (:) :: arrays
+
+       allocate (arrays(20))
+       do i = 1,20
+          allocate (arrays(i)%ap(i))
+       end do
+.fi
+arrays is an allocatable array (1 dimension) whose size is
+not known at compile time (it has
+a Dope Vector).  At run time, the
+allocate statement creats 20 array_ptr dope vectors
+and marks the base arrays dopevector as allocated.
+The myvar variable is just there to add complexity to
+the example :-)
+.nf
+In the loop, arrays(1)%ap(1) 
+    is allocated as a single element array of reals.
+In the loop, arrays(2)%ap(2) 
+    is allocated as an array of two reals.
+...
+In the loop, arrays(20)%ap(20) 
+    is allocated as an array of twenty reals.
+.fi
+.H 2 "the problem with standard dwarf and this example"
+.sp
+In dwarf, there is no way to find the array bounds of arrays(3)%ap,
+for example, (which are 1:3 in f90 syntax)
+since any location expression in an ap array lower bound
+attribute cannot involve the 3 (the 3 is known at debug time and
+does not appear in the running binary, so no way for the
+location expression to get to it).
+And of course the 3 must actually index across the array of
+dope vectors in 'arrays' in our implementation, but that is less of
+a problem than the problem with the '3'.
+.sp
+Plus dwarf has no way to find the 'allocated' flag in the
+dope vector (so the debugger can know when the allocate is done
+for a particular arrays(j)%ap).
+.sp
+Consequently, the calculation of array bounds and indices
+for these dynamically created f90 arrays
+is now pushed of into the debugger, which must know the
+field names and usages of the dope vector C structure and
+use the field offsets etc to find data arrays.
+C, C++, f77, and most f90 arrays continue to be described
+in standard dwarf.
+At the outer allocatable/assumed-shape/pointer
+the DW_AT_location points at the dope vector (so debugger
+calculations use that as a base).
+.P
+It would have been nice to design a dwarf extension
+to handle the above problems, but
+the methods considered to date were not
+any more consistent with standard dwarf than
+this dope vector centric approach: essentially just
+as much work in the debugger appeared necessary either way.
+A better (more dwarf-ish) 
+design would be welcome information.

+Here is dwarf information from the compiler for
+the example above, as printed by dwarfdump(1)
+.nf
+[Note:
+The following may not be the test.
+Having field names with '.' in the name is 
+not such a good idea, as it conflicts with the
+use of '.' in dbx extended naming.
+Something else, like _$, would be much easier
+to work with in dbx (customers won't care about this,
+for the most part, 
+but folks working on dbx will, and in those
+rare circumstances when a customer cares,
+the '.' will be a real problem in dbx.).
+Note that to print something about .base., in dbx one
+would have to do
+	whatis `.base.`
+where that is the grave accent, or back-quote I am using.
+With extended naming one do
+	whatis `.dope.`.`.base.`
+which is hard to type and hard to read.

+.H 2 "The dope vector structure details"
+A dope vector is the following C struct, "dopevec.h".
+Not all the fields are of use to a debugger.
+It may be that not all fields will show up
+in the f90 dwarf (since not all are of interest to debuggers).
+.nf
+[Note:
+Need details on the use of each field.
+And need to know which are really 32 bits and which
+are 32 or 64.
+end Note]
+The following
+struct 
+is a representation of all the dope vector fields.
+It suppresses irrelevant detail and may not
+exactly match the layout in memory (a debugger must
+examine the dwarf to find the fields, not
+compile this structure into the debugger!).
+.nf
+struct .dope. {
+ void *base;   // pointer to data
+ struct .flds. {
+  long el_len; // length of element in bytes?
+  unsigned int assoc:1;     //means?
+  unsigned int ptr_alloc:1;     //means?
+  unsigned int p_or_a:2;    //means?
+  unsigned int a_contig:1;  // means?
+  unsigned int num_dims: 3; // 0 thru 7
+  unsigned int type_code:32; //values?
+  unsigned int orig_base; //void *? means?
+  long         orig_size; // means?
+ } .flds;
+ 
+ struct .dope_bnd. {
+   long lb   ; // lower bound 
+   long ext  ;  // means?
+   long str_m; // means?
+ } .dims[7];
+}
+.fi
+
+.H 2 "DW_AT_MIPS_assumed_size       0x2011"
+This flag was invented to deal with f90 arrays.
+For example:
+
+.nf
+      pointer (rptr, axx(1))
+      pointer (iptr, ita(*))
+      rptr = malloc (100*8)
+      iptr = malloc (100*4)
+.fi
+
+This flag attribute has the value 'yes' (true, on) if and only if
+the size is unbounded, as iptr is.
+Both may show an explicit upper bound of 1 in the dwarf,
+but this flag notifies the debugger that there is explicitly
+no user-provided size.
+
+So if a user asks for a printout of  the rptr allocated
+array, the default will be of a single entry (as
+there is a user slice bound in the source).
+In contrast, there is no explicit upper bound on the iptr
+(ita) array so the default slice will use the current bound
+(a value calculated from the malloc size, see the dope vector).
+
+Given explicit requests, more of rptr(axx) can me shown
+than the default.
+
+.H 1 "Line information and Source Position"
+DWARF does not define the meaning of the term 'source statement'.
+Nor does it define any way to find the first user-written
+executable code in a function.
+.P
+It does define that a source statement  has a file name,
+a line number, and a column position (see Sec 6.2, Line Number
+Information of the Dwarf Version 2 document).
+We will call those 3 source coordinates a 'source position'
+in this document.  We'll try not to accidentally call the
+source position a 'line number' since that is ambiguous
+as to what it means.
+
+.H 2 "Definition of Statement"
+.P
+A function prolog is a statement.
+.P
+A C, C++, Pascal, or Fortran statement is a statement.
+.P
+Each initialized local variable in C,C++ is a statement
+in that its initialization generates a source position.
+This means that
+	x =3, y=4;
+is two statements.
+.P
+For C, C++:
+The 3 parts a,b,c in for(a;b;c) {d;} are individual statements.
+The condition portion of a while() and do {} while() is
+a statement.  (of course d; can be any number of statements)
+.P
+For Fortran, the controlling expression of a DO loop is a statement.
+Is a 'continue' statement in Fortran a DWARF statement?
+.P
+Each function return, whether user coded or generated by the
+compiler, is a statement.  This is so one can step over (in
+a debugger) the final user-coded statement 
+(exclusive of the return statement if any) in a function
+wile not leaving the function scope.
+.P
+
+.H 2 "Finding The First User Code in a Function"
+
+.nf
+Consider:
+int func(int a)
+{                    /* source position 1 */
+	float b = a; /* source position 2 */
+	int x;       
+	x = b + 2;   /* source position 3 */
+}                    /* source position 4 */
+.fi
+.P
+The DIE for a function gives the address range of the function,
+including function prolog(s) and epilog(s)
+.P
+Since there is no scope block for the outer user scope of a
+function (and thus no beginning address range for the outer
+user scope:  the DWARF committee explicitly rejected the idea
+of having a user scope block)
+it is necessary to use the source position information to find
+the first user-executable statement.
+.P
+This means that the user code for a function must be presumed
+to begin at the code location of the second source position in
+the function address range.
+.P
+If a function has exactly one source position, the function
+presumably consists solely of a return.
+.P
+If a function has exactly two source positions, the function
+may consist of a function prolog and a return or a single user
+statement and a return (there may be no prolog code needed in a
+leaf function).  In this case, there is no way to be sure which
+is the first source position of user code, so the rule is to
+presume that the first address is user code.
+.P
+If a function consists of 3 or more source positions, one
+should assume that the first source position is function prolog and
+the second is the first user executable code.
+
+.H 2 "Using debug_frame Information to find first user statement"
+In addition to the line information, the debug_frame information
+can be
+useful in determining the first user source line.
+.P
+Given that a function has more than 1 source position,
+Find the code location of the second source position, then
+examine the debug_frame information to determine if the Canonical
+Frame Address (cfa) is updated before the second source position
+code location.
+If the cfa is updated, then one can be pretty sure that the
+code for the first source position is function prolog code.
+.P
+Similarly, if the cfa is restored in the code for
+a source position, the source position is likely to
+represent a function exit block.
+
+.H 2 "Debugger Use Of Source Position"
+Command line debuggers, such as dbx and gdb, will ordinarily
+want to consider multiple statements on one line to be a single
+statement: doing otherwise is distressing to users since it
+causes a 'step' command to appear to have no effect.
+.P
+An exception for command line debuggers is in determining the
+first user statement: as detailed above, there one wants to
+consider the full  source position and will want to consider
+the function return a separate statement.  It is difficult to
+make the function return a separate statement 'step' reliably
+however if a function is coded all on one line or if the last
+line of user code before the return  is on the same line as the
+return.
+.P
+A graphical debugger has none of these problems if it simply
+highlights the portion of the line being executed.  In that
+case, stepping will appear natural even stepping within a
+line.
+.H 1 "Known Bugs"
+Up through at least MIPSpro7.2.1
+the compiler has been emitting form DW_FORM_DATA1,2, or 4
+for DW_AT_const_value in DW_TAG_enumerator.
+And dwarfdump and debuggers have read this with dwarf_formudata()
+or form_sdata() and gotten some values incorrect.
+For example, a value of 128 was printed by debuggers as a negative value.
+Since dwarfdump and the compilers were not written to use the
+value the same way, their output differed.
+For negative enumerator values the compiler has been emitting 32bit values
+in a DW_FORM_DATA4.
+The compiler should probably be emitting a DW_FORM_sdata for
+enumerator values.
+And consumers of enumerator values should then call form_sdata().
+However, right now, debuggers should call form_udata() and only if
+it fails, call form_sdata().
+Anything else will break backward compatibility with
+the objects produced earlier.
