2246 to close it. Update mips_relax.sizes[]. Emit fixups for the
2247 second version of a relaxable macro. Record the first relaxable
2248 fixup in mips_relax. Remove tc_gen_reloc workaround.
2249 (macro_build): Remove all uses of "place". Use mips_relax.sequence
2250 in the same way as in append_insn.
2251 (mips16_macro_build): Remove "place" argument.
2252 (macro_build_lui): As for macro_build. Don't drop the add_symbol
2253 when generating the second version of a relaxable macro.
2254 (load_got_offset, add_got_offset): New functions.
2255 (load_address, macro): Use new relaxation machinery. Remove
2256 tc_gen_reloc workarounds.
2257 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
2258 version of a relaxable macro is needed. Return -RELAX_SECOND if the
2259 first version is needed.

2261 (md_convert_frag): Go through the fixups for a relaxable macro and
2262 mark those that belong to the unneeded alternative as done. If the
2263 second alternative is needed, adjust the fixup addresses to account
2264 for the deleted first alternative.
