3646 (RELAX_FIRST, RELAX_SECOND): New.
3647 (mips_relax): New variable.
3648 (relax_close_frag, relax_start, relax_switch, relax_end): New fns.
3649 (append_insn): Remove "place" argument. Use mips_relax.sequence
3650 rather than "place" to check whether we're expanding the second
3651 alternative of a relaxable macro. Remove redundant check for
3652 branch relaxation. If generating a normal insn, and there
3653 is not enough room in the current frag, call relax_close_frag()
3654 to close it. Update mips_relax.sizes[]. Emit fixups for the
3655 second version of a relaxable macro. Record the first relaxable
3656 fixup in mips_relax. Remove tc_gen_reloc workaround.
3657 (macro_build): Remove all uses of "place". Use mips_relax.sequence
3658 in the same way as in append_insn.
3659 (mips16_macro_build): Remove "place" argument.
3660 (macro_build_lui): As for macro_build. Don't drop the add_symbol
3661 when generating the second version of a relaxable macro.
3662 (load_got_offset, add_got_offset): New functions.
3663 (load_address, macro): Use new relaxation machinery. Remove
3664 tc_gen_reloc workarounds.
3665 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
3666 version of a relaxable macro is needed. Return -RELAX_SECOND if the
3667 first version is needed.
3668 (tc_gen_reloc): Remove relaxation handling.
3669 (md_convert_frag): Go through the fixups for a relaxable macro and
3670 mark those that belong to the unneeded alternative as done. If the
3671 second alternative is needed, adjust the fixup addresses to account
3672 for the deleted first alternative.
