2739 * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of
2740 the first sequence, the size of the second sequence, and a flag
2741 that says whether we should warn.
2742 (RELAX_OLD, RELAX_NEW, RELAX_RELOC[123]): Delete.
2743 (RELAX_FIRST, RELAX_SECOND): New.
2744 (mips_relax): New variable.
2745 (relax_close_frag, relax_start, relax_switch, relax_end): New fns.
2746 (append_insn): Remove "place" argument. Use mips_relax.sequence
2747 rather than "place" to check whether we're expanding the second
2748 alternative of a relaxable macro. Remove redundant check for
2749 branch relaxation. If generating a normal insn, and there
2750 is not enough room in the current frag, call relax_close_frag()
2751 to close it. Update mips_relax.sizes[]. Emit fixups for the
2752 second version of a relaxable macro. Record the first relaxable
2753 fixup in mips_relax. Remove tc_gen_reloc workaround.
2754 (macro_build): Remove all uses of "place". Use mips_relax.sequence
2755 in the same way as in append_insn.
2756 (mips16_macro_build): Remove "place" argument.
2757 (macro_build_lui): As for macro_build. Don't drop the add_symbol
2758 when generating the second version of a relaxable macro.
2759 (load_got_offset, add_got_offset): New functions.
2760 (load_address, macro): Use new relaxation machinery. Remove
2761 tc_gen_reloc workarounds.
2762 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
2763 version of a relaxable macro is needed. Return -RELAX_SECOND if the
2764 first version is needed.
2765 (tc_gen_reloc): Remove relaxation handling.
2766 (md_convert_frag): Go through the fixups for a relaxable macro and
2767 mark those that belong to the unneeded alternative as done. If the
2768 second alternative is needed, adjust the fixup addresses to account
2769 for the deleted first alternative.
