555 alternative of a relaxable macro. Remove redundant check for
556 branch relaxation. If generating a normal insn, and there
557 is not enough room in the current frag, call relax_close_frag()

571 first version is needed.
572 (tc_gen_reloc): Remove relaxation handling.
573 (md_convert_frag): Go through the fixups for a relaxable macro and
574 mark those that belong to the unneeded alternative as done. If the

576 for the deleted first alternative.
