2317 * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of

2319 that says whether we should warn.

2325 rather than "place" to check whether we're expanding the second
2326 alternative of a relaxable macro. Remove redundant check for
2327 branch relaxation. If generating a normal insn, and there
2328 is not enough room in the current frag, call relax_close_frag()
2329 to close it. Update mips_relax.sizes[]. Emit fixups for the
2330 second version of a relaxable macro. Record the first relaxable
2331 fixup in mips_relax. Remove tc_gen_reloc workaround.
2332 (macro_build): Remove all uses of "place". Use mips_relax.sequence
2333 in the same way as in append_insn.
2334 (mips16_macro_build): Remove "place" argument.

2336 when generating the second version of a relaxable macro.
2337 (load_got_offset, add_got_offset): New functions.
2338 (load_address, macro): Use new relaxation machinery. Remove
2339 tc_gen_reloc workarounds.
2340 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
2341 version of a relaxable macro is needed. Return -RELAX_SECOND if the
2342 first version is needed.
2343 (tc_gen_reloc): Remove relaxation handling.
2344 (md_convert_frag): Go through the fixups for a relaxable macro and
2345 mark those that belong to the unneeded alternative as done. If the
2346 second alternative is needed, adjust the fixup addresses to account
2347 for the deleted first alternative.
