+ * We support four variants:
+ *
+ * - Fully ordered: The default implementation, no suffix required.
+ * - Acquire: Provides ACQUIRE semantics, _acquire suffix.
+ * - Release: Provides RELEASE semantics, _release suffix.
+ * - Relaxed: No ordering guarantees, _relaxed suffix.
+ *
+ * For compound atomics performing both a load and a store, ACQUIRE
+ * semantics apply only to the load and RELEASE semantics only to the
+ * store portion of the operation. Note that a failed cmpxchg_acquire
