2299 * config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): Remove.
2300 * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of
2301 the first sequence, the size of the second sequence, and a flag
2302 that says whether we should warn.
2303 (RELAX_OLD, RELAX_NEW, RELAX_RELOC[123]): Delete.
2304 (RELAX_FIRST, RELAX_SECOND): New.
2305 (mips_relax): New variable.
2306 (relax_close_frag, relax_start, relax_switch, relax_end): New fns.
2307 (append_insn): Remove "place" argument. Use mips_relax.sequence
2308 rather than "place" to check whether we're expanding the second
2309 alternative of a relaxable macro. Remove redundant check for
2310 branch relaxation. If generating a normal insn, and there
2311 is not enough room in the current frag, call relax_close_frag()
2312 to close it. Update mips_relax.sizes[]. Emit fixups for the
2313 second version of a relaxable macro. Record the first relaxable
2314 fixup in mips_relax. Remove tc_gen_reloc workaround.
2315 (macro_build): Remove all uses of "place". Use mips_relax.sequence
2316 in the same way as in append_insn.
2317 (mips16_macro_build): Remove "place" argument.
2318 (macro_build_lui): As for macro_build. Don't drop the add_symbol
2319 when generating the second version of a relaxable macro.
2320 (load_got_offset, add_got_offset): New functions.
2321 (load_address, macro): Use new relaxation machinery. Remove
2322 tc_gen_reloc workarounds.
2323 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
2324 version of a relaxable macro is needed. Return -RELAX_SECOND if the
2325 first version is needed.
2326 (tc_gen_reloc): Remove relaxation handling.
2327 (md_convert_frag): Go through the fixups for a relaxable macro and
2328 mark those that belong to the unneeded alternative as done. If the
2329 second alternative is needed, adjust the fixup addresses to account
2330 for the deleted first alternative.

2355
2356 * config/tc-mips.c (append_insn): Properly detect variant frags
2357 that preclude swapping of relaxed branches. Correctly swap
2358 instructions between frags when dealing with relaxed branches.
