2322 * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of

2330 rather than "place" to check whether we're expanding the second
2331 alternative of a relaxable macro. Remove redundant check for
2332 branch relaxation. If generating a normal insn, and there
2333 is not enough room in the current frag, call relax_close_frag()
2334 to close it. Update mips_relax.sizes[]. Emit fixups for the
2335 second version of a relaxable macro. Record the first relaxable
2336 fixup in mips_relax. Remove tc_gen_reloc workaround.
2337 (macro_build): Remove all uses of "place". Use mips_relax.sequence
2338 in the same way as in append_insn.
2339 (mips16_macro_build): Remove "place" argument.

2341 when generating the second version of a relaxable macro.
2342 (load_got_offset, add_got_offset): New functions.
2343 (load_address, macro): Use new relaxation machinery. Remove
2344 tc_gen_reloc workarounds.
2345 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
2346 version of a relaxable macro is needed. Return -RELAX_SECOND if the
2347 first version is needed.
2348 (tc_gen_reloc): Remove relaxation handling.
2349 (md_convert_frag): Go through the fixups for a relaxable macro and
2350 mark those that belong to the unneeded alternative as done. If the
2351 second alternative is needed, adjust the fixup addresses to account
2352 for the deleted first alternative.
