+December 8, 2007
+ Had to add an ugly configure conditional as libelf has
+ unconditional use of off64_t in recent libelf.h
+July 3, 2007
+ Now with -v dwarf expression blocks in frame operations
+ are printed expanded out.
+July 2, 2007
+ Added a new abi -x abi=general usable for any cpu with
+ up to 1000 registers.
+May 7, 2007
+ Sun Microsystems contributes new dwarf.h extensions and a new -G option
+ to dwarfdump -i (so one can see the 'global' offset to DIEs).
+ Thanks to Chris Quenelle of Sun.
+April 17, 2006
+ New -x name=<conf file> -x abi=<abiname> and configuration file
+ enable sensible printing of a wide range of .debug_frame eh_frame
+ correctly without recompiling dwarfdump or touching libdwarf.h or
+ dwarf.h.
+March 29, 2005
+ Now handles DWARF3. For non-MIPS objects, the list of register
+ names in print_sections.c is not appropriate, #define
+ DWARFDUMP_TURN_OFF_MIPS_REG_NAMES to turn off the MIPS names.
+December 1, 2005
+ Added new DWARF3 TAGs and ATtributes to the -k lists,
+ clarified the -k reporting, and made the build more robust
+ in the face of errors in the *.list relationship-spec-files.
+
+August 1, 2005
+ Now print_die.c deals with long loclists without a coredump.
+ Added esb.h esb.c (and testesb.c for testing) to encapsulate
+ getting space for possibly-long strings.
+ Now print_die.c uses snprintf() not sprintf (hopefully this
+ will not inconvenience anyone, snprintf() has been available
+ on most systems for years now).
+ Altered print of location lists a little bit - for better appearance.
+
+July 15, 2005
+ Now completely frees all allocated memory. Various
+ routines were not calling dealloc() code and
+ new libdwarf dealloc routines are now used where those
+ are needed.
+
+ Now prints DWARF3 .debug_pubtypes section (with -a or -y).
+ The .debug_pubtypes section and SGI-specific .debug_typenames
+ are equvalent so they are treated alike.
+
+Mar 21, 2005
+ The -f flag now prints only .debug_frame data. The .eh_frame section
+ (GNU exceptions data) now prints with -F (not -a).
+ Printing gcc 3.3 or 3.4 .eh_frame with zR augmentation
+ does not work at this time, so do not use -F
+ to print such an object.
+ The line section print now prints a CU-DIE offset for each such DIEs
+ line information. This makes it much easier to correctly associate
+ -l (or -v -l) output with -v -v -l when debugging a faulty
+ linetable in an executable.
+ With -v -v -l (two -v) the output of line info continues to be a
+ completely different format than zero or one -v, the two-v
+ form showing the detailed line table opcodes.
+ With g++ 3.3.3 one sees bad line addresses at times as the
+ DW_LNE_set_address address for header files do not always
+ get their relocations applied. I am told this is fixed in 3.4.x.
+
+
+Mar 18, 2005
+ In correcting printing of macro information the format
+ of the macro (-m) output has changed substantially.
+ Much more complete now. Still could use enhancement.
+
+Oct 28, 2004
+ Updated contact address in copyright: SGI moved 1/4 mile
+ to a new address: 1500 Crittenden Lane.
+
+Oct 02, 2003
+ Now fully supports .debug_loc section.
+
+June 14, 2001
+ Now calling a new function dwarf_get_arange_cu_header_offset()
+ in libdwarf and printing the returned cu header offset for
+ aranges entries. Making it easier to track down internal
+ errors in the dwarf2 data. Also added small other
+ consistency checks, printing a message and exit()ing on
+ error.
+
+April 14, 2000
+ The libdwarf copyright has changed to
+ version 2.1 of the GNU Lesser General Public License.
+ Anyone holding a version of libdwarf that was published
+ before this new copyright
+ is allowed to use
+ the copyright published in that earlier libdwarf source
+ on the earlier source
+ or to use
+ this new copyright on the earlier source,
+ at their option.
+
+July 21, 1999
+ Added gnu extensions to the frame information printer
+ and handling for egcs eh_frame printing.
+ libdwarf changes mean this now can print little-endian
+ object dwarf on a big-endian system and vice-versa.
+
+December, 1998
+ added dwarfdump to the dwarf public source distribution.
+
+June, 1994
+ libdwarf consumer interface changed completely so updated to match.
+
+May, 1993
+ Initial version of dwarfdump for dwarf version 2
+ written at sgi.
