        * config/i386/i386.md (cmpcc): New.
        * config/i386/sync.md (sync_compare_and_swap*): Set FLAGS_REG.
        (sync_compare_and_swap_cc*): Delete.

        * config/s390/s390.c (s390_compare_emitted): Remove.
        (s390_emit_compare): Handle MODE_CC s390_compare_op0 like
        s390_compare_emitted used to be handled.  Assert that modes match.
        (s390_emit_compare_and_swap): Use s390_emit_compare, do not
        refer to sync_compare_and_swap_ccsi.
        * config/s390/s390.h (s390_compare_emitted): Remove.
        * config/s390/s390.md (seq): Look for MODE_CC s390_compare_op0
        instead of s390_compare_emitted.
        (stack_protect_test, sync_compare_and_swap_cc): Set s390_compare_op0
        instead of s390_compare_emitted.
        * config/s390/s390.md (cmpcc): New.
        (sync_compare_and_swapqi, sync_compare_and_swaphi): Clobber
        CC_REGNUM, do not pretend it's set.
        (sync_compare_and_swap_cc*): Delete.
        * config/s390/predicates.md (cc_reg_operand): New.

        * expr.c (sync_compare_and_swap_cc): Delete.
        * optabs.h (sync_compare_and_swap_cc): Delete.
        * optabs.c (prepare_cmp_insn): Ignore which specific CCmode
        is being used with can_compare_p.
        (emit_cmp_and_jump_insn_1): Likewise when looking in the optab.
        (find_cc_set): New.
        (expand_bool_compare_and_swap): Do not use sync_compare_and_swap_cc,
        look for a MODE_CC set instead.  Use emit_store_flag.
        (expand_compare_and_swap_loop): Likewise, with some additional
        complication to avoid a force_reg when useless.  Use
        emit_cmp_and_jump_insns.
        * genopinit.c (optabs): Delete sync_compare_and_swap_cc.
        * doc/md.texi (sync_compare_and_swap_cc): Merge with
        sync_compare_and_swap documentation.
