2356 alternative of a relaxable macro. Remove redundant check for
2357 branch relaxation. If generating a normal insn, and there
2358 is not enough room in the current frag, call relax_close_frag()
2359 to close it. Update mips_relax.sizes[]. Emit fixups for the
2360 second version of a relaxable macro. Record the first relaxable

2369 tc_gen_reloc workarounds.

2371 version of a relaxable macro is needed. Return -RELAX_SECOND if the
2372 first version is needed.
2373 (tc_gen_reloc): Remove relaxation handling.
2374 (md_convert_frag): Go through the fixups for a relaxable macro and
2375 mark those that belong to the unneeded alternative as done. If the
2376 second alternative is needed, adjust the fixup addresses to account
2377 for the deleted first alternative.
