read. (bfd_error_system_call or bfd_error_file_truncated).
* som.c: Do not blindly set bfd_error_system_call after a
failing bfd_read, bfd_write, or bfd_seek. In a few places
(like som_object_p) override the error status set by bfd_read.
* aix386-core.c, aout-encap,c archive.c, bout.c: Likewise.
* coff-rs6000.c, coffgen.c ecoff.c, elf.c: Likewise.
* elf32-hppa.c, elfcode.h, hp300hpux.c, i386lynx.c: Likewise.

* som.c: Check return values from several bfd_{seek,read,write}
calls that we just assumed were not failing.
cruft (like the #pragma alloca for AIX).
In addition to that problem, the C alloca calls xmalloc, which
means checking for being out of memory can't work right. The
following changes remove all uses of alloca from BFD.
* hosts/solaris2.h: Remove alloca cruft.
* som.c: Replace alloca with a fixed size auto array.
* aoutx.h, elfcode.h, nlmcode.h, bout.c, coff-alpha.c, ecoff.c,
ecofflink.c, elf32-hppa.c, elf32-mips.c, linker.c, reloc.c, som.c:
Replace alloca with malloc and appropriate error checking and
freeing.
* linker.c: Replace alloca with obstack_alloc.
* libbfd.h: Rebuilt.
(aligncode): When shrinking, the addend should be set to the current offset in
the section plus the number of bytes of padding that will actually be retained.
(b_out_relax_section): If a section contains no relocations, don't bother
processing them.
(b_out_get_relocated_section_contents): Set reloc_done. Assert that
bfd_get_section_contents returns true. Check that relocs are properly ordered.
(b_out_get_relocated_section_contents, case ALIGNDONE): Assert that reloc's
addend falls between the current source offset and the raw size of the input
section.
Changed some indentation, deleted trailing whitespace, fixed some comments,
removed some "#if 1" lines.
(output_addr): New macro.
(calljx_callback, callj_callback, get_value, abs32code, aligncode,
b_out_get_relocated_section_contents): Use it for readability.
the symbol value and check for undefined symbols.
(get_value): If the symbol is undefined, look it up in the linker
hash table.
(b_out_get_relocated_section_contents): For PCREL24 and PCREL13
use get_value to get the symbol value and check for undefined
symbols.
* reloc16.c (bfd_coff_reloc16_get_value): If the symbol is
undefined, look it up in the linker hash table.
bfd_make_debug_symbol; they were already in the target structure.
* Adjusted all uses of JUMP_TABLE.
* coffgen.c, libcoff-in.h (coff_bfd_make_debug_symbol): Renamed
from coff_make_debug_symbol.
* libcoff.h: Updated accordingly.
* section.c (SEC_IS_COMMON): New section flag, needed for MIPS
ECOFF which has two common sections.
(bfd_com_section): Set SEC_IS_COMMON flag.
* bfd-in.h (bfd_is_com_section): New macro to test SEC_IS_COMMON.
* aoutx.h, archive.c, bout.c, coff-a29k.c, coff-m88k.c,
coff-mips.c, coffgen.c, ieee.c, oasys.c, reloc.c, syms.: Use
bfd_is_com_section macro rather than checking for equality to
bfd_com_section.
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.

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
* coff-i386.c, coff-i960.c, coff-m68k.c, coff-mips.c, coff-m88k.c,
coff-rs6000.c, coff-we32k.c, elf.c, ieee.c, srec.c: targets set
without leading underscore flag
* targets.c: add symbol leading char to xvec description
* bfd-in.h (bfd_get_symbol_leading_char): new macro.
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.
bout.c (b_out_squirt_out_relocs): treat abs sumbols the right way.
* reloc.c (bfd_perform-relocation): don't relocate refs to
absolute symbols if doing a partial link.
coff-h8300.c, coff-i386.c, coff-i960.c, coff-m68k.c, coff-m88k.c,
coff-mips.c, coff-rs6000.c, cpu-h300.c, elf.c, i386aout.c,
newos3.c, stab-syms.c, syms.c: All these files have had their
#includes altered to point to the new places.
* elf.c: Remove elf_set_section_contents, use generic one. Lint.
* libbfd-in.h, libbfd.c: Add bfd_generic_set_section_contents.
* libbfd.c (bfd_generic_{get,set}_section_contents): Check that
last byte of transfer, not first byte, is within the section.
* host-aout.c: Remove `BSD' archive support. Lint.
* archures.c: Rename `struct bfd_arch_info_struct' to `struct
bfd_arch_info'. Rename `typedef bfd_arch_info_struct_type' to
`bfd_arch_info_type'. All uses changed.
* reloc.c: Rename `bfd_reloc_status_enum_type' to
`bfd_reloc_status_type'. Rename `bfd_reloc_code_enum_real_type'
to `bfd_reloc_code_real_type'. (This seems to be a misnomer,
it needs a better name.) All uses changed.
* targets.c: Rename `enum target_flavour_enum' to `enum
target_flavour', and remove the `_enum' from all of the enum
values themselves. All uses changed.
* configure.in, config/h-i386mach: i386 mach host.
* config/t-i386-aout: Use host-aout.c.
* trad-core.c: Give it its own xvec's to make it independent
of other file formats.
* ecoff.c, host-aout.c: Remove refs to trad-core.
* config/t-dec3100, t-hp300bsd, t-tahoe, t-vax: Define TRAD_CORE.
* targets.c: #ifdef TRAD_CORE, include it in the vector.
