141 * nlmcode.h, liblnm.h, nlm32-alpha.c nlm32-i386.c nlm32-sparc.c:
142 The sparc (and possibly other?) NLM format requires a different
143 way to write exports, so add a write_export field to the backend
144 data (and set it to NULL for everything but the sparc).
146 Fri Jan 21 14:11:16 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
148 * sunos.c (MY(read_dynamic_relocs)): Compare info->dynrel with NULL,

1429 expanded within JUMP_TABLE, and ANSI compilers don't expand
1431 * mipsbsd.c (MY_bfd_reloc_type_lookup): Rename from
1432 MY_reloc_howto_type_lookup, and don't define in terms of MY.
1433 (MY_canonicalize_reloc): Don't define in terms of MY.
