551 alternative of a relaxable macro. Remove redundant check for
552 branch relaxation. If generating a normal insn, and there
553 is not enough room in the current frag, call relax_close_frag()
554 to close it. Update mips_relax.sizes[]. Emit fixups for the

564 tc_gen_reloc workarounds.

567 first version is needed.
568 (tc_gen_reloc): Remove relaxation handling.
569 (md_convert_frag): Go through the fixups for a relaxable macro and
570 mark those that belong to the unneeded alternative as done. If the
571 second alternative is needed, adjust the fixup addresses to account
572 for the deleted first alternative.
