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.

      * dwarf_print_lines.c pro_section.c dwarf_query.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.
