3203 * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of

3211 rather than "place" to check whether we're expanding the second
3212 alternative of a relaxable macro. Remove redundant check for
3213 branch relaxation. If generating a normal insn, and there
3214 is not enough room in the current frag, call relax_close_frag()
3215 to close it. Update mips_relax.sizes[]. Emit fixups for the
3216 second version of a relaxable macro. Record the first relaxable
3217 fixup in mips_relax. Remove tc_gen_reloc workaround.

3225 tc_gen_reloc workarounds.

3227 version of a relaxable macro is needed. Return -RELAX_SECOND if the
3228 first version is needed.
3229 (tc_gen_reloc): Remove relaxation handling.
3230 (md_convert_frag): Go through the fixups for a relaxable macro and
3231 mark those that belong to the unneeded alternative as done. If the
3232 second alternative is needed, adjust the fixup addresses to account
3233 for the deleted first alternative.
