From 744accb21bd7b45ad5d0bfd63dda028d86e2a09b Mon Sep 17 00:00:00 2001 From: Andrew MacLeod Date: Thu, 24 Nov 2011 23:14:31 +0000 Subject: optab.c (maybe_emit_atomic_exchange): New. 2011-11-24 Andrew MacLeod * 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. (expand_atomic_test_and_set, expand_atomic_clear): New prototypes.
