     * DWARFDUMPCOPYRIGHT: Added GPL copyright text with

       explanation of the intended content.

     * COPYING: added text explaining confusion of GPL vs LGPL.

       Thanks to Chris Quenelle for pointing out the disconnect

       between DWARFDUMPCOPYRIGHT and the source files in dwarfdump.

2006-12-21 David Anderson <davea@sgi.com>

     * tag_tree.list: add tags to make allowed list more complete.

       Omission noticed by Marcel Mettes.

2006-06-14 David Anderson <davea@sgi.com>

     * print_frames.c: Clean up printing of augmentation data  by

       eliminating dangling 0x (for eh_frame).

2006-04-28 David Anderson <davea@sgi.com>

     * dwarfdump.conf: Now has x86_64 register names.

       x86_64 with help from Tom Hughes (verified

       from independent sources). 

       Added m68k register names and refined  x86 list

       by looking at various information-sources.

2006-04-18 David Anderson <davea@sgi.com>

     * *.c: Ran indent so all now follow a standard look.

       handling variable-size frame data and different 

       frame rule initialization value.

     * dwconf.c: Add a default print for CFA in case of

       an omission in dwarfdump.conf. 

     * dwarfdump.conf: Move setup and rename the ABIs slightly.

2006-04-17 David Anderson <davea@sgi.com>

     * dwarfdump.conf: Correct typos. Remove some register names.

     * dwarfdump.c: Fix compiler warnings, fix -x option usage message.

     * dwconf.h: Fix compiler warnings by changing types.

     * dwconf.c: Change error checking so we check all errors, do

       not stop at first error. Ran indent.  Added code to check

       for extra junk after operand(s).

     * print_frames.c: Fix compiler warnings.

     * Makefile.in: get <prefix> used in install rule and creating

       places to search for dwarfdump.conf

2006-04-16 David Anderson <davea@sgi.com>

     * dwarfdump.conf: New dwarfdump configuration file. Makes using frame

           information easy to read and correct for any ABI/ISA

           without rebuilding dwarfdump.

     * Makefile.in: Added new files dwconf.h dwconf.c

     * dwconf.h dwconf.c: New files implement reading dwarfdump.conf

       and help print_frames.c print frame information correctly

       for ABIs specified at runtime.

     * dwarfdump.1: document -x commands.

     * globals.h: Minor changes to support dwarfdump.conf

     * print_frames.c: Major changes to support a run-time description of 

       the frames info and dwarfdump.conf.

     * print_frames.h: Changes  to support a run-time description of 

       the frames info and dwarfdump.conf.

     * print_sections.c: Minor tweaks to support a run-time 

       description of the frames info and dwarfdump.conf.

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

     * Makefile.in globals.h print_sections.c: Refer to new

       print_frames.h print_frames.c.

     * print_frames.h print_frames.c: Extract cie, fde printing

       to separate file, separating loop logic from the printing

       of an entry from the loop.

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

     * dwarfdump.c global.h print_sections.c: Preparing for 

       dwarf3 frame interface.

     * print_die.c: Corrects handling of DW_AT_encoding (etc) value.

2006-03-29 David Anderson <davea@sgi.com>

     * print_sections.c: define DWARFDUMP_TURN_OFF_MIPS_REG_NAMES 

       at compile time

       to turn off the MIPS register names printing.  Instead

       (aside from cfa) use a name like  r4 (where the DWARF 

       register number follows the letter 'r').

       Indent. Initialize some local variables at declarations.

2006-03-13 David Anderson <davea@sgi.com>

     * print_sections.c: Now gets gnu eh_augmentation data by calling

       dwarf_get_cie_augmentation_data() or dwarf_get_fde_augmentation_data()

       and prints it (use -v to see cie data).

       Now prints DWARF3 frame information.

2006-03-08 David Anderson <davea@sgi.com>

     * print_sections.c: Add 'break;' at line 710.

       Thanks to Richard Stuckey for noticing.

2005-12-01 David Anderson <davea@sgi.com>

     * dwarf_names.awk: use snprintf instead of sprintf for safety.

2005-12-01 David Anderson <davea@sgi.com>

     * Makefile.in: Build attr/tag trees with

       individual commands to catch build errors.

     * tag_attr.c,tag_tree.c: Verify that

       tables fit in the generated C code and check for 

       format errors in the *.list files.

     * tag_attr.list, tag_tree.list: Added some valid entries. 

     * globals.h: add DWARF_ERROR3 macro for better diagnostics.

     * print_die.c: Show both sides of questionable tag relation

       in CHECK  -k diagnostic output.

2005-11-25 David Anderson <davea@sgi.com>

     * print_die.c: DW_AT_stride_size changed to DW_AT_bit_stride,

                    added DW_AT_byte_stride.

     * tag_attr.c,tag_tree.c: fixed array size now a #define for

	readability.

     * tag_attr.list: Added DWARF3  attributes, also new TAGs.

     * tag_tree.list: Added DWARF3 TAGs.

2005-11-08 David Anderson <davea@sgi.com>

      * makename.c: remove non-standard malloc.h include,

        stdlib.h suffices and is already included.

2005-10-24 David Anderson <davea@sgi.com>

      * tag_attr.c tag_tree.c: added DWARF3 TAGs to string array.

2005-08-01 David Anderson <davea@sgi.com>

      * Makefile.in: Add esb.o and test rule (test code for esb.c).

      * dwarfdump.c:  Remove old static buffer initialization.

      * print_die.c: Use esb now, avoid crash due to long loclist

        overrunning static buffer. Uses snprintf now, not sprintf.

        snprintf is for safety.

      * esb.h esb.c: Adding extensible string buffer (esb) code.

      * testesb.c: Test code for esb.c.

      * print_reloc.c: size field is now Elf64_Xword for 

        Elf64  as Elf64_Word is only 32 bits.

2005-07-15 David Anderson <davea@sgi.com>

      * dwarfdump.c: Add print of .debug_pubtypes, remove

        erroneous dealloc after dwarf_formstring() call.

      * globals.h: Add declarations for .debug_pubtypes print.  Add

        declaration for full dealloc.

      * print_die.c: Remove erroneous dealloc after dwarf_formstring() call.

      * print_exception_tables.c: Call dwarf_fde_cie_list_dealloc()

        for complete dealloc.

      * print_sections.c: Remove incorrect dealloc() call.

        Add calls to new dealloc routines. Add support of .debug_pubtypes

        print.

2005-07-14 David Anderson <davea@sgi.com>

      * print_sections.c (print_line_numbers_this_cu): Use new

        dwarf_srclines_dealloc() for deallocation after

        dwarf_srclines() called.

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

      * print_sections.c: Factors out common print code into

        a new routine. Avoid indexing past end of register names

        array.  Adds checks and prints so that certain errors

        in pubnames-like sections are printed usefully (and dwarfdump

        then stops if libdwarf gave an error).

2005-03-21 David Anderson <davea@sgi.com>

      * dwarfdump.c: Add -F flag to

        request .eh_frame section print. Changed -f flag meaning

        to print .debug_frame only. -a flag no longer

	prints .debug_frame by default.

      * print_sections.c: avoid printing an eh_frame we don't understand.

	Add new information per CU when printing line info: specifically

        the line section offset.  

      * globals.h: Added arguments to print_frames() for -F flag.

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

      * print_sections.c: Correct macro section printing.

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

      * DWARFDUMPCOPYRIGHT config.h defs.h dwarfdump.c globals.h

	makename.c makename.h print_die.c print_exception_tables.c 

	print_reloc.c print_sections.c tag_attr.c tag_attr.list

	tag_tree.c tag_tree.list: Copyright update, SGI

        corporate address change.

2004-10-26 David Anderson <davea@sgi.com>

      * acconfig.h: removed. Was old style autoconf usage.

      * configure.in: Updated AC_DEFINE usage, adding args 2 & 3.

      * config.guess: Updated. timestamp='2004-06-11'.

      * config.sub: Updated.  timestamp='2004-03-12'.

      * configure config.h.in: regenerated with autoconf 2.58.

2004-05-14 David Anderson <davea@sgi.com>

      * print_die.c (print_die_and_children): Change to iteration

        on siblings (still recursing on children).

2004-03-30 David Anderson <davea@sgi.com>

      * dwarfdump.c (main): getopt() string should contain k:g

        not kg:    Thanks to Peter Seiderer for pointing this out.

2003-12-31 David Anderson <davea@sgi.com>

      * README: Added configure example.

      * Makefile.in: Removed bogus LIBS line, updated copyright date.

      * acconfig.h: Added LGPL copyright to match libdwarf

	Silly, but it matches libdwarf version boilerplate.

      * config.guess config.sub: new versions from automake-1.6.

      * config.h.in configure: Regenerated.

2003-10-06   David Anderson <davea@sgi.com>

     * dwarfdump.c print_sections.c: applied indent(1).

     * print_die.c: applied indent and added ; after

       invocations of macros PUSH_DIE_STACK POP_DIE_STACK SPACE

       as these were confusing indent a bit.

       The indent control file .indent.pro contained:

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

  	-l72  -lc72  -hnl  -nprs

  	-fca -i4  -lp -psl -npcs 

2003-10-02   David Anderson <davea@sgi.com>

     * dwarfdump.c: Add -g to indicate use of older 

       location entry code in libdwarf.  So dwarf_loclist 

       and dwarf_loclist_n are testable.

     * globals.h: Added use_old_dwarf_loclist flag so one

       can choose the old dwarf_loclist() interface.

       For testing.

     * print_die.c: Rearranged to avoid code duplication.

       Now supports .debug_loc fully.

     * print_sections.c: Prints .debug_loc now.

2003-09-29   David Anderson <davea@sgi.com>

      * print_die.c: with -v, print 'loclist' start and

	end addr and also a hint that DW_FORM_indirect is used.

        No change for normal output (for now).

2003-05-19   David Anderson <davea@sgi.com>

      * dwarfdump.c call dwarf_srcfiles() to get file names

        per cu and pass down to die print routines.

	Removed incorrect tests for when to print ".debug_info",

	leaving simpler test.

      * print_die.c globals.h: print file name (from line info)

	with DW_AT_decl_file, adding data from dwarf_srcfiles

	to argument list of a few routines to make that possible. 

      * print_sections.c: moved "line number info" string print so

	it prints for -v as well as normal  line ouput.

2002-10-23   Amaury Le Leyzour amaury@sgi.com

      * print_sections.c (print_weaknames): Changed

        DW_DLA_TYPENAME to DW_DLA_WEAK at dwarf_dealloc().

2002-10-22  Tom Hughes <thh@cyberscience.com>

      * print_sections.c: macro printing now supported.

      * dwarfdump.c: removed erroneous dwarf_dealloc()

        of string returned by dwarf_errmsg().

2002-11-22  David Anderson <davea@sgi.com>

      * dwarf_names.awk at_list.awk: Allow an name to have two 

        spellings so the historical name preserved yet the dwarf3 

        version is supported. First name seen is used/reported

        by dwarfdump.

      * dwarf.h:   DW_TAG_template_type_param(eter)

        DW_TAG_template_value_param(eter) DW_AT_namelist_itm(s)   

        are the ones with alternate spellings now.

        Added Universal Parallel C TAGs/Attributes in

	user namespace.

      * tag_attr.c tag_attr.list tag_tree.c tag_tree.list:

        Use the DW_TAG_template_* dwarf3 spellings.

2002-05-08  David Anderson <davea@sgi.com>

      * tag_attr.list dwarf.h: DW_AT_namelist_items is

	wrong, changed to DW_AT_namelist_item

2002-04-29  Stephen Clarke <stephen.clarke@superh.com>

      * dwarfdump.c (main): #ifdef for __CYGWIN__ on open().

2001-06-14  David Anderson <davea@sgi.com>

      * print_sections.c: Calling the new libdwarf function

	dwarf_get_arange_cu_header_offset() so we can print

	the cu header offset for aranges.

2000-07-14  Fred Fish  <fnf@ninemoons.com>

      * configure.in (LOCATION_OF_LIBELFHEADER): Fix typo for configure

      variable to be tested and enclose libelf/libelf.h in <>.

      * configure: Regenerated.

2000-07-10  Fred Fish  <fnf@ninemoons.com>

      * Makefile.in (install): Install dwarfdump.1 from $(srcdir).

2000 June 12   davea@sgi.com

  print_sections.c the DW_CFA_offset_extended print 

	did not multiply by data-alignment factor in the

	-v -v detailed output.

	And the offsets used %2d when the values were

	unsigned int, so now %2u.

	And not all cfa prints of values had

	necessarily a type to match

	%llu or %lld where required. Depended on the size of Dwarf_Signed

	and Dwarf_Unsigned.

	So now explicitly use cast to the

	right type to match the % format.

2000 April 13 davea@sgi.com

  print_sections.c - 1.56

        - A single byte of zero is a perfectly legitmate null 

          abbreviation entry          (in .debug_abbrev) 

	 now we print those directly and avoid a warning

          from dwarfdump

  print_die.c - 1.42

        - Explain what combo checker is doing and make it 

	  more maintainable (and fix bug which would 

	  not be hit, but was real enough (in combo checker),

	  using too large a number as highest tag number).

  tag_tree.list - 1.2

        - Add valid parent/child relationships so checker 

	  does not report valid entries as bogus.

2000 Feb 24

  Jason Merrill <jason@cygnus.com> noticed that gcc did

  not like   gcc -E foo.list, so  incorporated his fix so

  now the Makefile.in makes a link and does gcc -E _tmp.c

2000 Jan 26

  elena.demikhovsky@intel.com noticed that 3 statements in

  print_sections.c got warnings from the compiler

  she was using. Simple casts  (provided by her) fixed these.

1999 July 21

  davea@sgi.com 

  print_sections changed to allow printing

  of dwarf-ish egcs c++ .eh_frame data

1999 June 14

  Fred Fish fnf@ninemoons.com contributed

  autoconf'ing of the libdwarf and dwarfdump source.
