2744 longer sequence was chosen.

2748 * config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): Remove.
2749 * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of
2750 the first sequence, the size of the second sequence, and a flag
2751 that says whether we should warn.
2752 (RELAX_OLD, RELAX_NEW, RELAX_RELOC[123]): Delete.
2753 (RELAX_FIRST, RELAX_SECOND): New.
2754 (mips_relax): New variable.
2755 (relax_close_frag, relax_start, relax_switch, relax_end): New fns.
2756 (append_insn): Remove "place" argument. Use mips_relax.sequence
2757 rather than "place" to check whether we're expanding the second
2758 alternative of a relaxable macro. Remove redundant check for
2759 branch relaxation. If generating a normal insn, and there
2760 is not enough room in the current frag, call relax_close_frag()
2761 to close it. Update mips_relax.sizes[]. Emit fixups for the
2762 second version of a relaxable macro. Record the first relaxable
2763 fixup in mips_relax. Remove tc_gen_reloc workaround.
2764 (macro_build): Remove all uses of "place". Use mips_relax.sequence
2765 in the same way as in append_insn.
2766 (mips16_macro_build): Remove "place" argument.

2768 when generating the second version of a relaxable macro.
2769 (load_got_offset, add_got_offset): New functions.
2770 (load_address, macro): Use new relaxation machinery. Remove
2771 tc_gen_reloc workarounds.
2772 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
2773 version of a relaxable macro is needed. Return -RELAX_SECOND if the
2774 first version is needed.
2775 (tc_gen_reloc): Remove relaxation handling.
2776 (md_convert_frag): Go through the fixups for a relaxable macro and
2777 mark those that belong to the unneeded alternative as done. If the
2778 second alternative is needed, adjust the fixup addresses to account
2779 for the deleted first alternative.
