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

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

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

811 symbol has a value in the ECOFF symbol but not in the BFD symbol,
812 keep the value in the ECOFF symbol. This helps gas.
814 * linker.c (_bfd_generic_link_output_symbols,
815 _bfd_generic_link_write_global_symbol): Don't require that all
816 references to a common symbol be themselves common symbols.

860 * gen-aout.c (main): Set DEFAULT_ARCH based on preprocessor macros
861 (only testing for m68k and vax at the moment); do verify that the

864 compiling. Derive BYTES_IN_WORD and ARCH values from sizeof
866 * Makefile.in (aout-params.h): Pass gen-aout a dummy target name.
867 (check, installcheck): Identify directory in "no testsuites"

882 * linker.c (generic_link_add_symbol_list): If symbol is common,

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

1031 The sparc (and possibly other?) NLM format requires a different
1032 way to write exports, so add a write_export field to the backend
1033 data (and set it to NULL for everything but the sparc).

2267 Thu Nov 4 08:54:30 1993 Jeffrey A. Law (law@snake.cs.utah.edu)
2269 * From Pete Hoogenboom (hoogen@cs.utah.edu)
2270 * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
2271 in last change. Always rebuild symbol extension section the first
2272 time though if output sections exist (fixes ld -r problems).
2274 Thu Nov 04 08:08:46 1993 Jeffrey Wheat (cassidy@cygnus.com)

2280 * libbfd-in.h (artdata): Use long, not time_t for portability, at
2281 least to HPUX. File below is a derived file.
2283 Tue Nov 2 14:42:27 1993 Bill Cox (bill@tarkas.cygnus.com)
2285 * libbfd.h (artdata): Use long, not time_t for portability, at
2288 Tue Nov 2 09:32:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
2290 * config.bfd: Use bigmips for mips*-*-bsd*.
2292 Mon Nov 1 14:30:09 1993 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2294 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
2295 Handle symbol number of zero.
2297 * reloc.c (enum bfd_reloc_code_real): Added
2298 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
2299 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
2300 * bfd-in2.h: Rebuilt.
2301 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
2302 BFD_RELOC_MIPS_LITERAL.
2303 * elf32-mips.c (mips_reloc_map): Handle new relocs.
2304 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
2307 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
2308 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
2309 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
2310 MY_bfd_seclet_link): Define.
2311 (MY_bfd_reloc_type_lookup): Rename from
2312 MY_reloc_howto_type_lookup.
2313 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
2314 (MY(vec)): Use JUMP_TABLE rather than listing functions.
2315 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
2316 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
2317 terms of MY, because that causes a recusive invocation of CAT when
2318 expanded within JUMP_TABLE, and ANSI compilers don't expand
2320 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
2321 MY_reloc_howto_type_lookup, and don't define in terms of MY.
2322 (MY_canonicalize_reloc): Don't define in terms of MY.
2323 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
2324 than listing functions.
2326 Mon Nov 1 09:12:25 1993 Jim Kingdon (kingdon@lioth.cygnus.com)
