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