2006-12-05 David Anderson <davea@sgi.com>

      * dwarf_error.c, libdwarf.h: added 

        DW_DLE_FRAME_REGISTER_COUNT_MISMATCH.

      * dwarf_frame.c (_dwarf_exec_frame_instr): removed references

        to compile-time constants for register table size.  Now uses

        run-time-chosen sizes.  Now uses heap for reg table instead

        of stack. Now uses SIMPLE_ERROR_RETURN macro to simplify

        the code.

2006-11-08 David Anderson <davea@sgi.com>

      * pro_expr.c (dwarf_add_expr_gen): DW_OP_deref_size,

        DW_OP_xderef_size, and  DW_OP_pick were incorrect, missing

        & operator. Would coredump.  Thanks to Alan Chambers for mentioning

        the coredump.

2006-09-26 David Anderson <davea@sgi.com>

      * dwarf_die_deliv.c (dwarf_offdie): Now returns the

        correct die (worked before, almost always, but worked by accident).

        leave the defines visible (the defines are HP extensions).

      * libdwarf.h: Add new dwarf3 interface to frames.

        (which actually is also a better interface to dwarf2 info,

        not strictly for dwarf3).

      * dwarf_alloc.c: Add 'constructor/destructor' pointers 

        to the initialization table so we can handle a more 

        flexible (dwarf3) frame interface.Call the functions 

        at the appropriate times.

      * dwarf_frame.c: Using macro FDE_NULL_CHECKS_AND_SET_DBG

        using a macro BEGIN_LEN_SIZE to clarify and correct a few places.

2006-03-31 David Anderson <davea@sgi.com>

      * libdwarf.h: Added dwarf_get_fde_info_for_cfa_reg3() prototype

        preparing for dwarf3 frame interface.

      * dwarf_frame.c: Now uses separate rule, not DW_FRAME_CFA_COL, 

        to record CFA.

      * dwarf_frame.h: Add commentary on frame access.

2006-03-30 David Anderson <davea@sgi.com>

        Initialized some locals at declaration.

        Thanks to Mikael Vidstedt for noticing.

2006-03-23 David Anderson <davea@sgi.com>

      * dwarf_error.c: added error strings for codes 200,201

      * dwarf_line.c dwarf_line.h dwarf_print_lines.c dwarf_sort_line.c: Moved

        line prefix reading to a common routine, filling in a new internal

        struct to make it simple.  Removed much duplicate code.

        Added more support for dwarf3 line table standard opcodes.

        Now prints details (with -v -v) of standard opcodes it

      * dwarf_line.c: Added dwarf_srclines_dealloc and call it

        for dwarf_srclines output.  Does complete deallocation,

        unlike previous method, which was incomplete deallocation.

        Thanks to Alan Alexander for pointing out there was

        incomplete deallocation.

      * dwarf_print_lines.c: remove references and allocation

        of line_context. Memory was leaking due to unreferenced

        free elf resources with elf_end() call.

        Thanks to Cristi Vlasceanu for pointing out that a memory

        leak existed here.

2005-06-13 David Anderson <davea@sgi.com>

      * dwarf_frame.c (_dwarf_exec_frame_instr): Corrected test

        so that .o files (pre-relocation) are less likely to generate

2005-04-13 David Anderson <davea@sgi.com>

      * dwarf_error.c: Error  codes 194 and 195 were missing

	strings, added them to table.

          augmentation strings and avoid trying to handle these

          for now.

      * dwarf_global.c: Add an error check for

          pubnames-style sections for bad offset.

      * dwarf_init_finish.c: Add dwarf_get_section_max_offsets()

          to allow clients to do additional error checking.

          This code will have to change again, so leaving it

          undocumented. As written it's not useful for COMDAT

          style DWARF sections.

      * libdwarf.h: Added prototype for dwarf_get_section_max_offsets().

2005-03-31 David Anderson <davea@sgi.com>

      * dwarf_frame.h dwarf_frame.c: Added handling for 

        much (but not all) of gcc 3.3 gcc 3.4 .eh_frame

	'z' augmentation.  Gives error on attempting

        to get z augmentation data since such is not

        completely handled.

2005-03-18 David Anderson <davea@sgi.com>

      * dwarf_frame.h dwarf_frame.c: The gcc .eh_frame

        info did not print correctly so we now access the

	correct section data so it prints. Still no support

	for dwarf3 frame operators.

      * dwarf_macro.c: Detect end-of-macros properly

        (stopped too soon before).

2005-02-14 David Anderson <davea@sgi.com>

      * pro_incl.h: Added #elif defined(HAVE_LIBELF_H)

     *  configure.in libdwarfdefs.h: Now tests more precisely for __uint32_t

	and __uint64_t (previous test was not sufficient for debian/mips). 

	Regenerated configure config.h.in.

2004-10-28 David Anderson <davea@sgi.com>

      * dwarf_frame.c (_dwarf_exec_frame_instr):

        Was not setting ru_offset to 1 in DW_CFA_def_cfa_offset 

        case, now it does.

2004-02-24  David Anderson <davea@sgi.com>

      * dwarf_frame.c (_dwarf_exec_frame_instr):

        DW_CFA_def_cfa_register case, was setting offset, which

        is incorrect. Thanks to Tom Hughes <thh@cyberscience.com>

        for pointing this out.

2004-02-03 David Anderson <davea@sgi.com>

      * dwarf_util.h:  DECODE_LEB128_UWORD DECODE_LEB128_SWORD

        were simply wrong if  Dwarf_Word or

        Dwarf_Sword longer than 4 bytes. Upper bits left random. 

        Large values not extracted correctly.

2004-01-15 David Anderson <davea@sgi.com>

      * dwarf_alloc.c pro_alloc.c pro_init.c: changing BSD-ish bzero()

 	to posix-standard memset() calls.

      * configure.in: remove bstring.h test, add alloca.h test.

        No longer useing bzero, some environments have alloca 

	in malloc.h, no alloca.h.  If neither exist

2003-12-15 David Anderson <davea@sgi.com>

      * dwarf_init_finish.c (_dwarf_setup): test for (section_size)

        was wrong for eh_frame section. Changed this one to

	(section_size == 0) so it is like all the others testing 

	section_size.  Thanks to David Mosberger 

	for pointing out this inconsistency.

2003-12-08 David Anderson <davea@sgi.com>

      * dwarf_line.h: reference in comment to li_dbg meant to

      * dwarf_abbrev.c: Ensure the .debug_abbrev section is loaded.

      * dwarf_arange.c dwarf_global.c: Recent dwarf committee 

    	discussions have revealed we were wrong in not allowing 

	padding in aranges.

      * dwarf_die_deliv.c dwarf_query.c: handle DW_FORM_indirect.

      * dwarf_form.c: Add dwarf_whatform_direct() so folks

	can report on DW_FORM_indirect use.

	Fill in new Dwarf_Locdesc fields.

      * dwarf_loc.c: Handle .debug_loc  partially.

	Fill in new Dwarf_Locdesc fields.

	Load .debug_loc if not present and if it's needed.

      * dwarf_opaque.h: Added ar_attribute_form_direct field

  	so we can report DW_FORM_indirect

	in libdwarf-using code (where such wants to).

      * dwarf_util.c: Don't confuse DW_FORM_indirect uleb length 

	with other lengths.

      * libdwarf2.1.mm: Document new function dwarf_whatform_direct()

	Not needed by ordinary clients, just for clients

	wanting to print certain debug info.

2003-04-15 Brian Ford <ford@vss.fsi.com>

      * configure.in (AC_C_BIGENDIAN): Move after AC_PROG_CC so a proper

        working compiler is used for the test.

2003-01-21 David Anderson <davea@sgi.com>

      * dwarf_die_deliv.c (dwarf_next_cu_header, dwarf_offdie):

	Add calls to dwarf_load_object() to load .debug_info, 

        .debug_abbrev

      * dwarf_init_finish.c (_dwarf_setup): Remove calls to

        dwarf_load_object for .debug_info, .debug_abbrev sections.

      * dwarf_opaque.h: Add new fields to Dwarf_Debug so

        we don't need to pre-load .debug_info, .debug_abbrev

      * dwarf_util.h: Fix READ_AREA_LENGTH macro so it uses

        only length itself to determine which format the

        length is.

2003-01-14 David Anderson <davea@sgi.com>

      * dwarf_loc.c: Made comment at head of dwarf_loclist()

      a bit clearer.

2002-11-22 Tom Hughes <thh@cyberscience.com>

      * dwarf_macro.c: Corrected bugs in macro-info functions.

2002-10-29 David Anderson <davea@sgi.com>

      * dwarf_init_finish.c: The libelf_sgi mods

      left a HAVE_ELF64_GETSHDR ifdef in the wrong place 

      so folks without Elf64 could not build. Fixed.

2002-10-21 David Anderson <davea@sgi.com>

      * dwarf_form.c: the form_ref functions were failing to

      add in cc_extension_size when checking for offset

      legality. Thanks to Kelly O'Hair <kelly.ohair@sun.com>

      for pointing out the 4 places this was wrong.

      Used cu_context local pointer to avoid numerous

      double indirections.

2002-08-14 David Anderson <davea@sgi.com>

      * dwarf_string.c (dwarf_get_str): Return

      DW_DLV_NO_ENTRY when offset is just at the end of the

      sections, making it possible to use dwarf_get_str

      to print the section independently.

      * libdwarf2.1.mm, libdwarf2.1.ps: Document the

      revised dwarf_get_str interface (which was not

      fully thought thru before).

      * dwarf_line.c (dwarf_srcfiles): Avoid core dump

      when DW_AT_comp_dir absent (it's not required).

2002-07-31 David Anderson <davea@sgi.com>

      * pro_types.c (_dwarf_transform_simplename_to_disk): correct

      generation of .debug_info size field.

      Thanks to Kelly O'Hair <kelly.ohair@sun.com> for pointing out

      the bug.

2002-05-23 Daniel Gohman <gohmandj@sgi.com>

      * dwarf_init_finish.c: Add support for using SGI's

      ELF library as an alternative to using AT&T-style

      libelf.

      Add a new function _dwarf_load_section to handle

      loading of sections.

      * dwarf_opaque.h: Add entries to Dwarf_Debug_s to

      store section indicies.

      * most consumer files: Load sections on demand so

      that unneeded sections don't get loaded.

      * dwarf_init_finish.c: Fixed an incorrect check for

      duplicate .eh_frame sections.

2002-04-25 Kelly O'Hair <kelly.ohair@sun.com>

      * pro_section.c (_dwarf_pro_generate_debuginfo): add

      required dwarf2 sec 7.5.3 trailing null byte 

      to .debug_abbrev per compilation-unit.

2002-03-31 David Anderson <davea@sgi.com>

      * dwarf_abbref.c (dwarf_get_abbrev): change 

      DW_DLE_DEBUG_ABBREV_NULL to DW_DLE_DWARF_ABBREV_NULL. 

      Former was wrong code.

      * libdwarf2.1.mm: correct argument reference, returned_abbrev

      not returned_fde in dwarf_get_abbrev discussion.

2002-03-07 David Anderson <davea@sgi.com>

      * libdwarf.h: added struct Elf declaration

      to reduce dependency on header include ordering. 

2002-02-11 David Anderson <davea@sgi.com>

      * libdwarf2.1.mm libdwarf2.1.ps:

      dwarf_offdie can return DW_DLV_NO_ENTRY and that

      is now documented.

      * dwarf_loc.c: if the length of a location description

      is zero that is ok, not an error. dwarf2 sec 2.4.1.

2002-01-10 David Anderson <davea@sgi.com>

      * dwarf_opaque.h, dwarf_init_finish.c: if libdwarf does

      the elf_begin() it must also do the elf_end() to

      avoid a memory leak, and now does this correctly.

2002-01-10  David Anderson <davea@sgi.com>

      * dwarf_init_finish.c:  Using a variable to

      hold ELF_C_READ_MMAP.  Really motivated by

      code not added to this source. 

      * dwarf_die_deliv.c: Added comments, moved

      a couple variables to local scope from function scope.

      * dwarf.h: Added some #defines which were specified in the Dwarf

      2.1 Dwarf draft 5 (now called dwarf 3 draft 5).

2001-09-18  David Anderson davea@sgi.com

	* all files: applied gnu indent with

	-bad -bap -nbbo -br -ce -brs 

	-l72  -lc72  -hnl  -nprs  

	-fca -i4  -lp -psl -npcs 

	Code should use this set in libdwarf.

2001-08-21  "kelly o'hair" <kelly.ohair@eng.sun.com>

	* pro_section.c:  If one called dwarf_add_file_decl()

	  or dwarf_add_directory_decl() but never added a line,

	  .debug_line was not produced.  This was a mistake,

	  as if any file or directory was provided .debug_line

	  should be produced. 

2001-08-06  davea@sgi.com

	* libdwarf2.1.mm: documented dwarf_dealloc rules

	  more clearly. (.ps updated too)

	* mips_extensions.mm: documented the way SGI

	  gets frame stack pointer out of debug_frame.

	  (.ps updated too)

2001-06-14  davea@sgi.com

	* dwarf_leb.c: changed around where bytes counted in

	  _dwarf_decode_s_leb128 so it's easier to tell it is correct.
