2251 (RELAX_FIRST, RELAX_SECOND): New.
2252 (mips_relax): New variable.
2253 (relax_close_frag, relax_start, relax_switch, relax_end): New fns.
2254 (append_insn): Remove "place" argument. Use mips_relax.sequence
2255 rather than "place" to check whether we're expanding the second
2256 alternative of a relaxable macro. Remove redundant check for
2257 branch relaxation. If generating a normal insn, and there
2258 is not enough room in the current frag, call relax_close_frag()
2259 to close it. Update mips_relax.sizes[]. Emit fixups for the
2260 second version of a relaxable macro. Record the first relaxable
2261 fixup in mips_relax. Remove tc_gen_reloc workaround.
2262 (macro_build): Remove all uses of "place". Use mips_relax.sequence
2263 in the same way as in append_insn.
2264 (mips16_macro_build): Remove "place" argument.
2265 (macro_build_lui): As for macro_build. Don't drop the add_symbol
2266 when generating the second version of a relaxable macro.
2267 (load_got_offset, add_got_offset): New functions.
2268 (load_address, macro): Use new relaxation machinery. Remove
2269 tc_gen_reloc workarounds.
2270 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
2271 version of a relaxable macro is needed. Return -RELAX_SECOND if the
2272 first version is needed.
2273 (tc_gen_reloc): Remove relaxation handling.
2274 (md_convert_frag): Go through the fixups for a relaxable macro and
2275 mark those that belong to the unneeded alternative as done. If the
2276 second alternative is needed, adjust the fixup addresses to account
2277 for the deleted first alternative.
