58 branch relaxation. If generating a normal insn, and there
59 is not enough room in the current frag, call relax_close_frag()

75 (md_convert_frag): Go through the fixups for a relaxable macro and
76 mark those that belong to the unneeded alternative as done. If the
77 second alternative is needed, adjust the fixup addresses to account
78 for the deleted first alternative.
