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 + 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> + * dwarf.h: Added dwarf extensions reported + on the dwarf-workgroup mailing list by John DelSignore. +2009-03-19 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.
