Both are atomic, but the cmpxchg has memory ordering hints. We give this acquire semantics. NOTE: The unlock in libc_r is implemented by a "normal" assign statement. This is not correct on ia64 due to the memory ordering characteristics of the architecture. We need release semantics for an unlock. |
