3526 needs a warning and the other doesn't. Emit a warning if the
3527 longer sequence was chosen.
3529 2004-01-23 Richard Sandiford <rsandifo@redhat.com>
3531 * config/tc-mips.h (tc_frag_data_type, TC_FRAG_TYPE): Remove.
3532 * config/tc-mips.c (RELAX_ENCODE): Take three arguments: the size of
3533 the first sequence, the size of the second sequence, and a flag
3534 that says whether we should warn.
3535 (RELAX_OLD, RELAX_NEW, RELAX_RELOC[123]): Delete.
3536 (RELAX_FIRST, RELAX_SECOND): New.
3537 (mips_relax): New variable.
3538 (relax_close_frag, relax_start, relax_switch, relax_end): New fns.
3539 (append_insn): Remove "place" argument. Use mips_relax.sequence
3540 rather than "place" to check whether we're expanding the second
3541 alternative of a relaxable macro. Remove redundant check for
3542 branch relaxation. If generating a normal insn, and there
3543 is not enough room in the current frag, call relax_close_frag()
3544 to close it. Update mips_relax.sizes[]. Emit fixups for the
3545 second version of a relaxable macro. Record the first relaxable
3546 fixup in mips_relax. Remove tc_gen_reloc workaround.
3547 (macro_build): Remove all uses of "place". Use mips_relax.sequence
3548 in the same way as in append_insn.
3549 (mips16_macro_build): Remove "place" argument.
3550 (macro_build_lui): As for macro_build. Don't drop the add_symbol
3551 when generating the second version of a relaxable macro.
3552 (load_got_offset, add_got_offset): New functions.
3553 (load_address, macro): Use new relaxation machinery. Remove
3554 tc_gen_reloc workarounds.
3555 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
3556 version of a relaxable macro is needed. Return -RELAX_SECOND if the
3557 first version is needed.
3558 (tc_gen_reloc): Remove relaxation handling.
3559 (md_convert_frag): Go through the fixups for a relaxable macro and
3560 mark those that belong to the unneeded alternative as done. If the
3561 second alternative is needed, adjust the fixup addresses to account
3562 for the deleted first alternative.

3589 that preclude swapping of relaxed branches. Correctly swap
3590 instructions between frags when dealing with relaxed branches.
3592 2004-01-14 Maciej W. Rozycki <macro@ds2.pg.gda.pl>
