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

1434 expanded within JUMP_TABLE, and ANSI compilers don't expand
1436 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
1437 MY_reloc_howto_type_lookup, and don't define in terms of MY.
1438 (MY_canonicalize_reloc): Don't define in terms of MY.
