(sort_reloc_map): New function.
(sparc_reloc_map): New variable.

someday.

different class, but the same index number occur consecutively.
(get_section_entry): nicer name for sections being forward
referenced. (ieee_archive_p): don't free the filename string,
since it was never malloced.
Tue Oct 27 12:24:34 1992 Ian Lance Taylor (ian@cygnus.com)
* coffcode.h (coff_swap_aux_out): set the fcnary info before
optionally setting the dimen info, since they are in the same
memory locations. Also zero out external auxent.

* coff-m68k.c (m68k_howto2type, SELECT_RELOC): new function to
work out a coff relocation type from a howto's attributes rather
than using the input r_type field. This fixes PR1677 and allows

TWO_DATA_SECS, check for .data2
(coff_set_section_contents): set vma of .lib section to number of
.lib sections.
* coff-i386.c: define TWO_DATA_SECS; use a special CALC_ADDEND;
don't define coff_write_armap to bsd_write_armap.
* hosts/i386v.h: don't include <utime.h>, since it is not provided
by SVR3.2.
coffcode.h, elf.c, ieee.c, libaout.h, libbfd.c, oasys.c,
sco-core.c: Lint: Second argument of bfd_seek is always file_ptr.

doesn't match. Don't lose if file sections have already been created.

(slurp_symbol_table): Use header byte order, not target byte order, for reading
symbol data.
Thu Oct 8 08:52:48 1992 Steve Chamberlain (sac@thepub.cygnus.com)
Now a bfd knows whether underscores are normally prepended
to symbols in its file format. Helps with error messages.
* aout-adobe.c, aout-target.h, bout.c, coff-a29k.c, coff-h8300.c,
coff-z8k.c: targets set so they have leading underscore

coffcode.h (coff_write_relocs): removed sanity check until it
works on all targets (per advice from sac).
config/hp9000.mh: new file to define USG.
hppa.c: #undef hppa before the JUMP_TABLE.
hosts/hppahpux.h: #define NATIVE_HPPAHPUX_COMPILER if not
__STDC__.
targets.c (bfd_target_list): if NATIVE_HPPAHPUX_COMPILER, make
local variable target volatile to avoid mysterious bug in
HP9000/700 cc.
* aout-adobe.c: New file. So far, only reads a.out.adobe. FIXME.
* config/adobe.mt: Add.
* configure.in (*-adobe-* target): Add.
* targets.c (a_out_adobe_vec): Add.
* Makefile.in: add aout-adobe.c.
* configure.in: Put two dashes in all entries to be matched.
Add comments to remind people to do this.
Reorder all entries that match manufacturer names, to occur
last, so they will only be matched if no more specific match
occurs. Remove manufacturers `aout', `bout', `coff', and `elf'.
* coff-z8k.c: getting closer
* coffcode.h (coff_get_relocated_section_contents): allow
EXTRA_CASES hooks for different arches to provide different reloc
types.
* seclet.h: #ifndef around it to allow multiple inclusion

FASCIST_FDOPEN.
* hosts/rs6000.h, hosts/tahoe.h, hosts/vaxbsd.h: Remove
all FASCIST_FDOPEN config defines.
* archive.c (bfd_slurp_bsd_armap): if the symdef_count is too
large, assume we're using a swapped byte order and fail with
wrong_format rather than dumping core.
* targets.c, config/i960-bout.mt, hosts/*: added
HOST_BIG_ENDIAN_DEFAULT_VECTOR and
HOST_LITTLE_ENDIAN_DEFAULT_VECTOR because bout archive format
depends on the endianness of the host. Added #define
HOST_BIG_ENDIAN_P and #undef HOST_BIG_ENDIAN_P to a number of
configuration files in hosts/ (it was already in some).
from a coff file (csym is null), dont deref them
* ieee.c (parse_expression): get the answer right when adding an
abs+(sec+off), (ieee_generic_stat_arch_elt): call ieee_object_p
on elts so that filename is filled in.
Tue Aug 18 12:57:45 1992 Ian Lance Taylor (ian@cygnus.com)
* Makefile.in: added FLAGS_TO_PASS, and used it for all recursive
invocations of make. Also, always create installation
directories.
* config/apollov68.mh: removed -g from CC definition.
* libaout.h (struct aout_backend_data): New callback "set_sizes".
* aout-target.h (callback): Don't set page/seg sizes.

(sunos4_aout_backend): Point to it.

the default. Given that we *write* the suckers (for long
archive member names), we really ought to be able to read them!
* trad-core.c: Don't include <machine/reg.h>. It doesn't
seem to be needed, and many machines don't have it.
pointers to bfd_byte* before performing arithmetic on them. Such
use with bare void* pointers is a gcc extension.
* cache.c (bfd_cache_delete): Forward decl with prototype form.
* archive (normalize): Add to CONST to match actual usages with
CONST.
* elf.c (bfd_section_from_shdr, elf_section_from_bfd_section,
section_from_elf_index): Add SHT_BEPROGBITS case for i860 in
big endian mode.
* elf.c (bfd_section_from_shdr): Test for the possibility that
section_from_elf_index returns NULL and don't dereference it.
* bout.c (bout_swap_exec_header_[in_out]): new field in exec
header e_relaxable, major hackery in callbacks
* libaout.h : add space for a_relaxable.

* reloc.c->libbfd.h: change protype of bfd_default_reloc_type_lookup
* targets.c: change jump table vector to above
its prototype will be included in libbfd.h. Change result type
to struct * (rather than equivalent typedef) so it can be used in
the prototype, where they typedef won't be known.
* libbfd.h: Updated version.
Correct misconception that there can be only one symbol table.
Only call elf_slurp_symbol_table on the full symbol table, not
the dynamic one which is only a subset of the full one.
(The bfd library was slurping in the first ELF symbol table it
found and then ignoring any others. For dynamically linked
executables, this happened to be the dynamic symbol table, which
is a subset of the full symbol table and only contains the
symbols that need to be used in dynamic linking.)
Various changes to get linker working again for a.out:
* don't set/adjust section file positions or vmas more than once
* use correct page size and segment size when calculating them
* deal with some variations in a.out implementations
Tested on sun4 and sun4->sun3 so far, will be testing further but
needed to get wider exposure&testing. See ChangeLog for details.
Also:
* coffcode.h (coff_write_relocs): Write out swapped reloc, not
pre-swapped version.
* hosts/sparc.h (abort, exit): Hide these names if compiling with
gcc version 2, to avoid warnings.
