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.
