+2007-12-09 DavidAnderson <davea42@earthlink.net>
+ * 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
+ recent DWARF4 DW_AT_high_pc change.
+ Correct FSF address.
+ * libdwarf2p.1.mm: Document dwarf_add_AT_dataref()
+ and dwarf_add_AT_ref_address().
+ * libdwarf2p.1.pdf: Regenerate.
+ * dwarf.h: Update FSF address.
+ * dwarf_opaque.h: Add DWARF4 entry (version stamp).
+ Update FSF address.
+ * dwarf_die_deliv.c: Add check for .debug_info version 4
+ (version stamp). Update FSF address.

+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.
