        * elf32-hppa.c (hppa_elf_get_section_contents): Fix logic error
        in last change.  Always rebuild symbol extension section the first

        * config.bfd: Use bigmips for mips*-*-bsd*.

Mon Nov  1 14:30:09 1993  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)

        * elfcode.h (elf_slurp_reloca_table, elf_slurp_reloc_table):
        Handle symbol number of zero.

        * reloc.c (enum bfd_reloc_code_real): Added
        BFD_RELOC_MIPS_LITERAL, BFD_RELOC_MIPS_GOT16,
        BFD_RELOC_MIPS_CALL16, BFD_RELOC_MIPS_GPREL32.
        * bfd-in2.h: Rebuilt.
        * coff-mips.c (mips_bfd_reloc_type_lookup): Handle
        BFD_RELOC_MIPS_LITERAL.
        * elf32-mips.c (mips_reloc_map): Handle new relocs.

        MY_canonicalize_reloc, MY_write_object_contents): Don't define in
        terms of MY, because that causes a recusive invocation of CAT when
        expanded within JUMP_TABLE, and ANSI compilers don't expand
        recursive macros.
        * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
        MY_reloc_howto_type_lookup, and don't define in terms of MY.
