4096 * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of

4104 rather than "place" to check whether we're expanding the second
4105 alternative of a relaxable macro. Remove redundant check for
4106 branch relaxation. If generating a normal insn, and there
4107 is not enough room in the current frag, call relax_close_frag()
4108 to close it. Update mips_relax.sizes[]. Emit fixups for the
4109 second version of a relaxable macro. Record the first relaxable
4110 fixup in mips_relax. Remove tc_gen_reloc workaround.

4112 in the same way as in append_insn.

4118 tc_gen_reloc workarounds.
4119 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
4120 version of a relaxable macro is needed. Return -RELAX_SECOND if the
4121 first version is needed.
4122 (tc_gen_reloc): Remove relaxation handling.
4123 (md_convert_frag): Go through the fixups for a relaxable macro and
4124 mark those that belong to the unneeded alternative as done. If the
4125 second alternative is needed, adjust the fixup addresses to account
4126 for the deleted first alternative.
