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

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

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

848 bfd_som_set_subsection_attributes): Change parameters from char

933 * elfcode.h (swap_out_syms): Use elf_section_from_bfd_section to

2252 * reloc.c (enum bfd_reloc_code_real): Added
2253 BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
2254 BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
2255 * bfd-in2.h: Rebuilt.
2256 * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
2257 BFD_RELOC_MIPS_LITERAL.
2258 * elf32-mips.c (mips_reloc_map): Handle new relocs.
2259 (mips_elf_hi16_reloc, mips_elf_lo16_reloc): Rearrange _gp_disp
2262 * aout-target.h (MY_bfd_debug_info_start, MY_bfd_debug_info_end,
2263 MY_bfd_debug_info_accumulat [sic]): Remove unused definitions.
2264 (MY_bfd_get_relocated_section_contents, MY_bfd_relax_section,
2265 MY_bfd_seclet_link): Define.
2266 (MY_bfd_reloc_type_lookup): Rename from
2267 MY_reloc_howto_type_lookup.
2268 (MY_bfd_make_debug_symbol): Rename from MY_make_debug_symbol.
2269 (MY(vec)): Use JUMP_TABLE rather than listing functions.
2270 * hp300hpux.c (MY_get_symtab, MY_get_symtab_upper_bound,
2271 MY_canonicalize_reloc, MY_write_object_contents): Don't define in
2272 terms of MY, because that causes a recusive invocation of CAT when
2273 expanded within JUMP_TABLE, and ANSI compilers don't expand
2275 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
2276 MY_reloc_howto_type_lookup, and don't define in terms of MY.
2277 (MY_canonicalize_reloc): Don't define in terms of MY.
2278 (aout_mips_little_vec, aout_mips_big_vec): Use JUMP_TABLE rather
2279 than listing functions.
