91 * Makefile.in (BFD32_BACKENDS): Remove nlm32-alpha.o.

1055 * configure.bfd: make unixware equivalent to sysv4.
1057 * config/i386-nlm.mt: bring in elf config; make it the default.
1061 * libbfd.c (bfd_put_8): Add parens around reference to "val"
1066 * hosts/i386mach3.h (HOST_SEGMENT_SIZE),
1067 i386mach3.c (SEGMENT_SIZE, TEXT_START_ADDR): Correct values (?).
1071 * coffcode.h (coff_write_object_contents): Zero out internal_a.
1075 * aoutx.h, archive.c, archures.c, bfd.c, cache.c, coffcode.h,
1076 core.c, ctor.c, format.c, init.c, libbfd.c, opncls.c, reloc.c,
1077 section.c, syms.c, targets.c:
1078 Doc cleanup (spelling, punctuation, grammar, formatting).
1079 * bfd-in2.h, libbfd.h: Rebuild.
1083 * bfd-in.h (bfd_get_cacheable, bfd_set_cacheable): New accessors.
1084 * bfd.c, opncls.c: Improve comments on file descriptor cacheing.
1089 * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
1090 in last change. Always rebuild symbol extension section the first
1091 time though if output sections exist (fixes ld -r problems).
1095 * Makefile.in: Add .PHONY for check and installcheck rules.
1099 * libbfd-in.h (artdata): Use long, not time_t for portability, at
1100 least to HPUX. File below is a derived file.
1104 * libbfd.h (artdata): Use long, not time_t for portability, at
1109 * config.bfd: Use bigmips for mips*-*-bsd*.
1113 * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
1114 Handle symbol number of zero.
1116 * reloc.c (enum bfd_reloc_code_real): Added
1117 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
1118 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
1119 * bfd-in2.h: Rebuilt.
1120 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
1121 BFD_RELOC_MIPS_LITERAL.
1122 * elf32-mips.c (mips_reloc_map): Handle new relocs.
1123 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
1126 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
1127 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
1128 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
1129 MY_bfd_seclet_link): Define.
1130 (MY_bfd_reloc_type_lookup): Rename from
1131 MY_reloc_howto_type_lookup.
1132 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
1133 (MY(vec)): Use JUMP_TABLE rather than listing functions.
1134 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
1135 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
1136 terms of MY, because that causes a recusive invocation of CAT when
1137 expanded within JUMP_TABLE, and ANSI compilers don't expand
1139 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
1140 MY_reloc_howto_type_lookup, and don't define in terms of MY.
1141 (MY_canonicalize_reloc): Don't define in terms of MY.
1142 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
1143 than listing functions.
1147 * config.bfd: Use m68k-elf for m68*-*-sysv4*.
