 113         (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
 114         version of a relaxable macro is needed.  Return -RELAX_SECOND if the
 115         first version is needed.
 116         (tc_gen_reloc): Remove relaxation handling.
 117         (md_convert_frag): Go through the fixups for a relaxable macro and
 118         mark those that belong to the unneeded alternative as done.  If the
 119         second alternative is needed, adjust the fixup addresses to account
 120         for the deleted first alternative.

 134
 135         * config/tc-m68hc11.c (build_indexed_byte): movb and movw cannot
