+2009-12-30 DavidAnderson <davea42@earthlink.net>
+ * 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.mm: Document 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.

+2009-05-10 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

+ * libdwarf.h, dwarf_frame.c: Added dwarf_set_frame_cfa_value().
+ Added dwarf_set_frame_rule_initial_value() as proper
+ spelling of dwarf_set_frame_rule_inital_value(), keeping
+ the old spelling for compatibility.
+ * libdwarf2.1.mm: Documented Added dwarf_set_frame_cfa_value(),
+ corrected spelling to dwarf_set_frame_rule_initial_value().
+ * libdwarf2.1.pdf: Regenerated.
+ * dwarf_opaque.h: Added field de_frame_cfa_col_number so that
+ we do not need to use magic macros at execution time.
+ * dwarf_init_finish.c: Now sets de_frame_cfa_col_number,
+ de_frame_same_value_number, and de_frame_undefined_value_number.
+2009-02-02 DavidAnderson <davea42@earthlink.net>
+ * dwarf.h: Added dwarf extensions reported by
+ John Bishop.
+2009-03-30 DavidAnderson <davea42@earthlink.net>

+ * libdwarf.h: Expanded comments.
+ * dwarf_die_deliv.c: Expanded comments.
+2009-03-16 DavidAnderson <davea42@earthlink.net>
+ * libdwarf.h: Fixed several instances of
+ inconsistent indentation. Documented arguments
+ to dwarf_uncompress_integer_block().
+2009-02-17 DavidAnderson <davea42@earthlink.net>
+ * dwarf_print_lines.c,dwarf_line.c,dwarf_frame.c: C99-isms

+ * README: document --enable-nonstandardprintf
+
+2009-02-13 DavidAnderson <davea42@earthlink.net>
+ * libdwarf.h: Added argument to dwarf_print_lines()
+ for better error reporting. Added dwarf_check_lineheader()
+ which allows some error reporting when not calling dwarf_print_lines().
+ * dwarf_print_lines.c: Implements dwarf_check_lineheader() now.
+ * dwarf_sort_line.c: Match up with new arguments to
+ dwarf_read_line_table_prefix().
+ * dwarf_line.c: Implement new arguments to
