* configure.in (i[34]86-*-sco*): use target i386-sco.
* config/i386-sco.mt: new file; define SCO_CORE.
application. Some of the linker flags ought to get moved to this field
someday.
archures.c (bfd_default_scan): Recognize a few more numbers: 80486, 80960,
and 960.
bfd-in.h, bfd.c, targets.c, coffcode.h, coff-mips.c, other targets: Moved COFF
swap table to backend data.
hosts/i386linux.h: Include unistd.h.
aoutx.h, libaout.h, stab-syms.c: stab names are now in constant storage.
trad-core.c: Fixed some `PARAMS' uses that were missing parentheses.

binutils, bfd or opcodes uses it.
Mon Nov 2 12:36:14 1992 Ian Lance Taylor (ian@cygnus.com)
* config/delta88.mh, config/hp300.mh, config/hppahpux.mh,
config/i386v.mh: removed -DUSG from HDEFINES.
hosts/delta88.h, hosts/hp300.h, hosts/hppahpux.h, hosts/i386v.h:
defined USE_UTIME.
hosts/i386v.h: don't define POSIX_UTIME.
* ieee.c (get_symbol): can now cope when two symbols of a
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_write_symbol): don't zero external auxent; now done in
coff_swap_aux_out.
* seclet.c (rel): don't load sections without the SEC_LOAD bit.
Thu Oct 15 10:16:35 1992 Steve Chamberlain (sac@thepub.cygnus.com)
* 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
conversion of a.out relocs to coff relocs.
* coffcode.h (coff_write_relocs): if supplied a relocation
relative to an absolute symbol, use the right symbol index.
* reloc.c (bfd_perform_relocation): do a partial link for coff
relocs right.
* changes to support i386-sysv with shared libraries:
* coffcode.h (sec_to_styp_flags): if TWO_DATA_SECS is defined,
check for .data2; if _LIB is defined, check for it; map

if section has contents, not just if it is loadable; if
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.
Third argument is SEEK_SET or SEEK_CUR. Result is always 0 or -1.

* config/i386bsd.mh: New file for core file support.
* hosts/i386bsd.h: Merge changes from Peter Schauer.
* bout.c (ALIGN): Rename to ALIGNER, since system header files
on BSD 4.4 define ALIGN (sigh!).
* aoutx.h (some_aout_object_p): Restore old aout_data value if this type
doesn't match. Don't lose if file sections have already been created.
(set_arch_mach): Set reloc_entry_size.
(slurp_symbol_table): Use bfd_h_get_{16,8} for reaeding symbol data.
* hosts/i386bsd.h: New file.

(MY_reloc_howto_type_lookup): Don't define it.
* aoutx.h (adjust_sizes_and_vmas): Don't bother with padding for OMAGIC files.
(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.

* 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
* srec.c: minor doc fix
* coffcode.h (coff_renumber_symbols): set the last renumbered
symbol pointer to NULL, as expected by coff_write_linenumbers.
(coff_write_relocs): apparently a non-zero addend is OK for reloc
type R_IHCONST used on the 29k.
update, based on how the underlying file was opened. Obsoletes
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.

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 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.

SEC_NEVER_LOAD, various other bfdgas newness
* 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

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.

fix problem where a relocation which crossed a modification byte
boundary did not work. Fix problem where a relocation near the end
of a data record did not work.

structure before initializing the fields that are used, so that the unused
fields are in a known state. Two of these structures are memcmp'd so
any fields not explicitly initialized must be set to a known state.

if they make sense as independent sections; symbols and relocs are
turned into BFD symbols and relocs; objects are now created.
objdump and copy mostly work on .o files.
this check-in will be followed by gdb testing.
the code has *not* yet been split up the way coff is to
support multiple architectures and bit widths.
no ChangeLog entries yet; too big... nearly everything changed.
* configure.in: Add new host and target configs.
* elf.c (bfd_prstatus, bfd_fpregset): Avoid typename of register
structs, which vary; just use member name.

symbol addresss for undefined symbols.
* coff-rs6000.c: Various updates (due to target-
independent changes).

table only gets it's linenumbers relocated once. Modifed
(coff_write_native_symbol) and (coff_make_empty_symbol) to make
* aout-target.h: Use TARGET_BIG_ENDIAN_P to set up vector.
