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

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

773 (coff_write_symbols): Initialize debug_string_size to 0. If
774 bfd_coff_symname_in_debug returns true, don't put symbol name in

801 keep the value in the ECOFF symbol. This helps gas.
803 * linker.c (_bfd_generic_link_output_symbols,
804 _bfd_generic_link_write_global_symbol): Don't require that all

882 bfd_som_set_subsection_attributes): Change parameters from char
883 to int. Following a prototype with an old-style function definition
884 in the presence of widened parameters is a GCC-ism not supported

943 .pdata section based on lnnoptr field, not section header.

1021 way to write exports, so add a write_export field to the backend
1022 data (and set it to NULL for everything but the sparc).

2258 * From Pete Hoogenboom (hoogen@cs.utah.edu)
2259 * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
2260 in last change. Always rebuild symbol extension section the first
2261 time though if output sections exist (fixes ld -r problems).
2263 Thu Nov 04 08:08:46 1993 Jeffrey Wheat (cassidy@cygnus.com)
2265 * Makefile.in: Add .PHONY for check and installcheck rules.
2267 Tue Nov 2 14:42:27 1993 Bill Cox (bill@tarkas.cygnus.com)
2269 * libbfd-in.h (artdata): Use long, not time_t for portability, at
2270 least to HPUX. File below is a derived file.
2272 Tue Nov 2 14:42:27 1993 Bill Cox (bill@tarkas.cygnus.com)
2274 * libbfd.h (artdata): Use long, not time_t for portability, at
2277 Tue Nov 2 09:32:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
2279 * config.bfd: Use bigmips for mips*-*-bsd*.
2281 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2283 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
2284 Handle symbol number of zero.
2286 * reloc.c (enum bfd_reloc_code_real): Added
2287 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
2288 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
2289 * bfd-in2.h: Rebuilt.
2290 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
2291 BFD_RELOC_MIPS_LITERAL.
2292 * elf32-mips.c (mips_reloc_map): Handle new relocs.
2293 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
2296 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
2297 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
2298 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
2299 MY_bfd_seclet_link): Define.
2300 (MY_bfd_reloc_type_lookup): Rename from
2301 MY_reloc_howto_type_lookup.
2302 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
2303 (MY(vec)): Use JUMP_TABLE rather than listing functions.
2304 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
2305 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
2306 terms of MY, because that causes a recusive invocation of CAT when
2307 expanded within JUMP_TABLE, and ANSI compilers don't expand
2309 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
2310 MY_reloc_howto_type_lookup, and don't define in terms of MY.
2311 (MY_canonicalize_reloc): Don't define in terms of MY.
2312 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
2313 than listing functions.
2315 Mon Nov 1 09:12:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
2317 * config.bfd: Use m68k-elf for m68*-*-sysv4*.
