optab.c (maybe_emit_atomic_exchange): New.
2011-11-24 Andrew MacLeod <amacleod@redhat.com>
* optab.c (maybe_emit_atomic_exchange): New. Try to emit an
atomic_exchange pattern.
(maybe_emit_sync_lock_test_and_set): New. Try to emit an exchange
using __sync_lock_test_and_set.
(maybe_emit_compare_and_swap_exchange_loop): New. Try to emit an
exchange using a compare_and_swap loop.
(expand_sync_lock_test_and_set): New. Expand sync_lock_test_and_set.
(expand_atomic_test_and_set): New. Expand test_and_set operation.
(expand_atomic_exchange): Use new maybe_emit_* functions.
(expand_atomic_store): Use new maybe_emit_* functions.
* builtins.c (expand_builtin_sync_lock_test_and_set): Call
expand_sync_lock_test_and_set routine.
(expand_builtin_atomic_exchange): Remove parameter from call.
(expand_builtin_atomic_clear): Use atomic_clear pattern if present.
(expand_builtin_atomic_test_and_set): Add target and simply call
expand_atomic_test_and_set.
(expand_builtin): Add target to expand_builtin_atomic_test_and_set.
* expr.h (expand_atomic_exchange): Add parameter.
(expand_sync_lock_test_and_set): New prototype.
