130 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic
131 number rather than HP9000S800_ID. Note som.c is careful

250 use for bounds checking.
252 * linker.c (default_indirect_link_order): In assertion, compare
253 link_order size field against cooked size, not raw size, of input
256 * bout.c (b_out_get_reloc_upper_bound): For BSS section, just
258 (aligncode): When shrinking, the addend should be set to the
259 current offset in the section plus the number of bytes of padding
260 that will actually be retained.
261 (b_out_relax_section): If a section contains no relocations, don't
262 bother processing them.

347 Make all callers of malloc or realloc (including via obstacks)
348 check the result for NULL. Most set bfd_error to no_memory and
349 return in that case; a few are harder to fix, and are marked

720 bfd_coff_symname_in_debug returns true, don't put symbol name in

828 bfd_som_set_subsection_attributes): Change parameters from char

966 The sparc (and possibly other?) NLM format requires a different
967 way to write exports, so add a write_export field to the backend
968 data (and set it to NULL for everything but the sparc).

1018 read_dynamic_relocs fields.
1019 * aout-target.h (MY(backend_data)): Initialize

1129 * ecofflink.c: Extensive changes to compress and merge debugging

1134 sym_filepos as well.
1135 (ecoff_get_extr): Use ifdmap instead of ifdbase.

1201 * nlmcode.h (nlm_object_p): If we can't read the fixed header,
1202 count it as a wrong format error, not a system call error, since

1310 to unsigned int, because size_t may not be defined in bfd.h.

1351 and do the swapping here rather than calling ntohl from the N_*

2249 (MY(vec)): Use JUMP_TABLE rather than listing functions.
2250 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
2251 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
2252 terms of MY, because that causes a recusive invocation of CAT when
2253 expanded within JUMP_TABLE, and ANSI compilers don't expand
2255 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
2256 MY_reloc_howto_type_lookup, and don't define in terms of MY.
2257 (MY_canonicalize_reloc): Don't define in terms of MY.
2258 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
2259 than listing functions.
