175 * som.c (som_prep_headers): Use CPU_PA_RISC1_0 for magic

393 check the result for NULL. Most set bfd_error to no_memory and
394 return in that case; a few are harder to fix, and are marked

729 * aoutx.h (aout_link_check_ar_symbols): Correct test for whether

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

873 bfd_som_set_subsection_attributes): Change parameters from char

1012 way to write exports, so add a write_export field to the backend
1013 data (and set it to NULL for everything but the sparc).

2260 * libbfd-in.h (artdata): Use long, not time_t for portability, at
2261 least to HPUX. File below is a derived file.
2263 Tue Nov 2 14:42:27 1993 Bill Cox (bill@tarkas.cygnus.com)
2265 * libbfd.h (artdata): Use long, not time_t for portability, at
2268 Tue Nov 2 09:32:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
2270 * config.bfd: Use bigmips for mips*-*-bsd*.
2272 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2274 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
2275 Handle symbol number of zero.
2277 * reloc.c (enum bfd_reloc_code_real): Added
2278 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
2279 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
2280 * bfd-in2.h: Rebuilt.
2281 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
2282 BFD_RELOC_MIPS_LITERAL.
2283 * elf32-mips.c (mips_reloc_map): Handle new relocs.
2284 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
2287 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
2288 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
2289 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
2290 MY_bfd_seclet_link): Define.
2291 (MY_bfd_reloc_type_lookup): Rename from
2292 MY_reloc_howto_type_lookup.
2293 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
2294 (MY(vec)): Use JUMP_TABLE rather than listing functions.
2295 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
2296 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
2297 terms of MY, because that causes a recusive invocation of CAT when
2298 expanded within JUMP_TABLE, and ANSI compilers don't expand
2300 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
2301 MY_reloc_howto_type_lookup, and don't define in terms of MY.
2302 (MY_canonicalize_reloc): Don't define in terms of MY.
2303 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
2304 than listing functions.
2306 Mon Nov 1 09:12:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
2308 * config.bfd: Use m68k-elf for m68*-*-sysv4*.
