2009-12-30 DavidAnderson * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * 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 * libdwarf2p.1.mm: Improved the discussion of dwarf_transform_to_disk_form. * libdwarf2p.1.pdf: Regenerated. 2009-08-12 DavidAnderson * 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 * 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 * 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 * gennames.c: Change include from getopt.h to unistd.h so the code is more universally compilable. 2009-07-24 DavidAnderson * dwarf_frame.c: Change debug printf to use libdwarf.h DW_PR macros instead of %d. 2009-07-20 DavidAnderson * 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 * 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 * dwarf_elf_access.c: some cases had = where == was needed in the reloc switch code. 2009-07-05 DavidAnderson * 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 * 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 * 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 * 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 * dwarf.h: added new DWARF4 attribute (etc) defines. 2009-05-10 DavidAnderson * 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 * Makefile.in: Ensure temp files all get deleted. 2009-05-04 DavidAnderson * 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 * 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 * dwarf.h: Added dwarf extensions reported by John Bishop. 2009-03-30 DavidAnderson * dwarf.h: Added dwarf extensions reported on the dwarf-workgroup mailing list by John DelSignore. 2009-03-19 DavidAnderson * libdwarf.h: Expanded comments. * dwarf_die_deliv.c: Expanded comments. 2009-03-16 DavidAnderson * libdwarf.h: Fixed several instances of inconsistent indentation. Documented arguments to dwarf_uncompress_integer_block(). 2009-02-17 DavidAnderson * dwarf_print_lines.c,dwarf_line.c,dwarf_frame.c: C99-isms of // comments and declarations-in-code do not belong in libdwarf. 2009-02-14 DavidAnderson * libdwarf.h: Add support for compile-time definition of the format for Dwarf_Unsigned types. Using macros for DW_PR_DUx etc. * dwarf_print_lines.c: Use the DW_PR_DUx macros. * 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. * dwarf_line.c: Use the DW_PR_DUx macros. * dwarf_frame2.c: Use the DW_PR_DUx macros. * README: document --enable-nonstandardprintf 2009-02-13 DavidAnderson * 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 dwarf_read_line_table_prefix() for better error reporting. Allow erroneous ARM-compiler line table header to be used. * dwarf_line.h: Adding new argument to dwarf_read_line_table_prefix so we can report back on minor errors in the line table prefix. 2009-01-31 DavidAnderson * libdwarf.h: Corrected DW_DLE_LAST. * dwarf_frame.c: Remove accidental use of C99 mid-block variable definition.
