marcel 448c522a41 Implement the lock with a cmpxchg instruction instead of a xchg. ... 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.		2002-11-16 17:05:06 +00:00
