* 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.

* builtins.c (compareAndSwapLong_builtin,
compareAndSwapInt_builtin, compareAndSwapObject_builtin,
VMSupportsCS8_builtin): Do not look at sync_compare_and_swap_cc.
