2309 * config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): Remove.
2310 * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of
2311 the first sequence, the size of the second sequence, and a flag
2312 that says whether we should warn.
2313 (RELAX_OLD, RELAX_NEW, RELAX_RELOC[123]): Delete.
2314 (RELAX_FIRST, RELAX_SECOND): New.
2315 (mips_relax): New variable.
2316 (relax_close_frag, relax_start, relax_switch, relax_end): New fns.
2317 (append_insn): Remove "place" argument. Use mips_relax.sequence
2318 rather than "place" to check whether we're expanding the second
2319 alternative of a relaxable macro. Remove redundant check for
2320 branch relaxation. If generating a normal insn, and there
2321 is not enough room in the current frag, call relax_close_frag()
2322 to close it. Update mips_relax.sizes[]. Emit fixups for the
2323 second version of a relaxable macro. Record the first relaxable
2324 fixup in mips_relax. Remove tc_gen_reloc workaround.
2325 (macro_build): Remove all uses of "place". Use mips_relax.sequence
2326 in the same way as in append_insn.
2327 (mips16_macro_build): Remove "place" argument.
2328 (macro_build_lui): As for macro_build. Don't drop the add_symbol
2329 when generating the second version of a relaxable macro.
2330 (load_got_offset, add_got_offset): New functions.
2331 (load_address, macro): Use new relaxation machinery. Remove
2332 tc_gen_reloc workarounds.
2333 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
2334 version of a relaxable macro is needed. Return -RELAX_SECOND if the
2335 first version is needed.
2336 (tc_gen_reloc): Remove relaxation handling.
2337 (md_convert_frag): Go through the fixups for a relaxable macro and
2338 mark those that belong to the unneeded alternative as done. If the
2339 second alternative is needed, adjust the fixup addresses to account
2340 for the deleted first alternative.
