2307 (RELAX_FIRST, RELAX_SECOND): Turn into 8-bit quantities.
2308 (RELAX_USE_SECOND): Bump to 0x10000.
2309 (RELAX_SECOND_LONGER, RELAX_NOMACRO, RELAX_DELAY_SLOT): New flags.
2310 (mips_macro_warning): New variable.
2311 (md_assemble): Wrap macro expansion in macro_start() and macro_end().
2312 (s_cpload, s_cpsetup, s_cprestore, s_cpreturn): Likewise.
2313 (relax_close_frag): Set mips_macro_warning.first_frag. Adjust use
2314 of RELAX_ENCODE.

2316 (macro_start, macro_warning, macro_end): New functions.
2317 (macro_build): Don't emit warnings here.

2320 needs a warning and the other doesn't. Emit a warning if the
2321 longer sequence was chosen.

2324
2325 * config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): Remove.
2326 * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of
2327 the first sequence, the size of the second sequence, and a flag
2328 that says whether we should warn.
2329 (RELAX_OLD, RELAX_NEW, RELAX_RELOC[123]): Delete.
2330 (RELAX_FIRST, RELAX_SECOND): New.
2331 (mips_relax): New variable.

2333 (append_insn): Remove "place" argument. Use mips_relax.sequence
2334 rather than "place" to check whether we're expanding the second
2335 alternative of a relaxable macro. Remove redundant check for
2336 branch relaxation. If generating a normal insn, and there
2337 is not enough room in the current frag, call relax_close_frag()
2338 to close it. Update mips_relax.sizes[]. Emit fixups for the
2339 second version of a relaxable macro. Record the first relaxable
2340 fixup in mips_relax. Remove tc_gen_reloc workaround.
2341 (macro_build): Remove all uses of "place". Use mips_relax.sequence
2342 in the same way as in append_insn.
2343 (mips16_macro_build): Remove "place" argument.
2344 (macro_build_lui): As for macro_build. Don't drop the add_symbol
2345 when generating the second version of a relaxable macro.
2346 (load_got_offset, add_got_offset): New functions.
2347 (load_address, macro): Use new relaxation machinery. Remove
2348 tc_gen_reloc workarounds.
2349 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
2350 version of a relaxable macro is needed. Return -RELAX_SECOND if the
2351 first version is needed.
2352 (tc_gen_reloc): Remove relaxation handling.
2353 (md_convert_frag): Go through the fixups for a relaxable macro and
2354 mark those that belong to the unneeded alternative as done. If the
2355 second alternative is needed, adjust the fixup addresses to account
2356 for the deleted first alternative.

2382 * config/tc-mips.c (append_insn): Properly detect variant frags
2383 that preclude swapping of relaxed branches. Correctly swap
2384 instructions between frags when dealing with relaxed branches.
