3 * config/tc-ia64.c (emit_one_bundle): Snapshot manual bundling state
4 before actually using it. Don't generate an error in manual bundling
5 mode when looking at an insn requiring slot 2 but not yet at slot 2.
6 Don't generate an error in manual bundling mode when looking at an
7 insn required to be last in its group but the required slot hasn't
8 been reached, yet. Allow conversion from MII to MI;I for bundle
9 consisting of only 2 insns with the stop between them. Suppress
10 various meaningless errors resulting from detecting earlier ones.

2689 (append_insn): Remove "place" argument. Use mips_relax.sequence
2690 rather than "place" to check whether we're expanding the second
2691 alternative of a relaxable macro. Remove redundant check for
2692 branch relaxation. If generating a normal insn, and there
2693 is not enough room in the current frag, call relax_close_frag()
2694 to close it. Update mips_relax.sizes[]. Emit fixups for the
2695 second version of a relaxable macro. Record the first relaxable
2696 fixup in mips_relax. Remove tc_gen_reloc workaround.
2697 (macro_build): Remove all uses of "place". Use mips_relax.sequence
2698 in the same way as in append_insn.
2699 (mips16_macro_build): Remove "place" argument.
2700 (macro_build_lui): As for macro_build. Don't drop the add_symbol
2701 when generating the second version of a relaxable macro.
2702 (load_got_offset, add_got_offset): New functions.
2703 (load_address, macro): Use new relaxation machinery. Remove
2704 tc_gen_reloc workarounds.
2705 (md_estimate_size_before_relax): Set RELAX_USE_SECOND if the second
2706 version of a relaxable macro is needed. Return -RELAX_SECOND if the
2707 first version is needed.
2708 (tc_gen_reloc): Remove relaxation handling.
2709 (md_convert_frag): Go through the fixups for a relaxable macro and
2710 mark those that belong to the unneeded alternative as done. If the
2711 second alternative is needed, adjust the fixup addresses to account
2712 for the deleted first alternative.
