abbreviations table.
2008-04-04 DavidAnderson <davea42@earthlink.net>
* libdwarf.h: A trivial change to make a declaration look better.
* dwarf_abbrev.h: We record tags in more than 16 bits now just in case
we encounter such a thing (increased ab_tag field size), though
we should not find such.
* dwarf_abbrev.c: Adding a comment about the dwarf TAG value.
* dwarf_util.c: Initialize local variables at declaration for safety.
Removed truncation of some values: internally record more bits.
Rewrote handling of the abbrev table as the old one did not scale
to large numbers of abbreviations (things got very slow).
* dwarf_util.h: Now has a larger field size in the argument to
_dwarf_get_abbrev_for_code (not quite necessary but not harmful).
* dwarf_die_deliv.c: Initializing local variables at declaration and
removing truncation of bits from some uleb values.
* dwarf_die_deliv.h: Increased size of ab_code field.
* dwarf_opaque.h: Added a comment about abbreviations.
* dwarf_base_types.h: Revised to match addition of new
allocation table entry.
* dwarf_alloc.h: Document macro definitions and increase one to
match new table size.
* dwarf_alloc.c: Arrange handling of new DW_DLA_HASH_TABLE_ENTRY
(most of the work done in dwarf_util.c).
2008-02-27 DavidAnderson <davea42@earthlink.net>

and dwarf_elf_access.c.

have been removed.
* dwarf_opaque.h: The elf related info is removed and Dwarf_Debug_s
now contains a new structure (from libdwarf.h) to hide object
information.
* dwarf_elf_access.c: All the Elf-using code is now in this
source file and elf details are kept in a struct defined and
used here. Non-libelf and non-elf object access code would
write a new source file with their own details using this
as an example.
* dwarf_elf_access.h: Prototypes for calling between
dwarf_original_elf_init.c and dwarf_elf_access.c.
2008-02-18 DavidAnderson <davea42@earthlink.net>

moved here from dwarf_init_finish.c.

and dwarf_original_elf_init.c can communicate.
2008-02-08 DavidAnderson <davea42@earthlink.net>
* dwarf_print_lines.c: Added commentary to clarify that
dwarf_print_lines() and _dwarf_print_lines are intentionally
identical. Initialized local variables so they are alll
visibly set to some sensible value.
2008-02-07 DavidAnderson <davea42@earthlink.net>
* dwarf_frame.c (_dwarf_fde_section_offset): A typo
in the last release made this an infinite loop.
A one character change fixed it. Thanks to Carlos Alberto
Enciso for noticing the bug.

selection of DWARF3 64bit extension producer offset generation.

* pro_init.c (dwarf_producer_init): Now standard DWARF3 is the default.
* configure.in: Add --enable-dwarf-format-sgi-irix for those
wanting IRIX offset-style DWARF2. Add --enable-dwarf-format-strict-32bit
for those wanting strictly 32bit offsets.
Otherwise default to generating 64bit offsets from the producer code,
but allow the DWARF3 extended 64bit offsets if the flag
DW_DLC_OFFSET_SIZE_64 is turned on in the call to dwarf_producer_init().
* config.h.in: Provide undefs for the offset macros.
2008-01-25 DavidAnderson <davea42@earthlink.net>
* pro_die.c: Changed leading tabs to spaces.
2008-01-23 DavidAnderson <davea42@earthlink.net>
* pro_die.c: Using di_last_child field dwarf_die_link
goes from O(N) to O(1) in adding a child.
Thanks to Daniel Gollub for the suggestion.
An omission in linking left/right children is fixed.
