+/*
+ * From Oracle SPARC Architecture 2015:
+ *
+ *   Compatibility notes: The PSO memory model described in SPARC V8 and
+ *   SPARC V9 compatibility architecture specifications was never implemented
+ *   in a SPARC V9 implementation and is not included in the Oracle SPARC
+ *   Architecture specification.
+ *
+ *   The RMO memory model described in the SPARC V9 specification was
+ *   implemented in some non-Sun SPARC V9 implementations, but is not
+ *   directly supported in Oracle SPARC Architecture 2015 implementations.
+ *
+ * Therefore always use TSO in QEMU.
+ *
+ * D.5 Specification of Partial Store Order (PSO)
+ *   ... [loads] are followed by an implied MEMBAR #LoadLoad | #LoadStore.
+ *
+ * D.6 Specification of Total Store Order (TSO)
+ *   ... PSO with the additional requirement that all [stores] are followed
+ *   by an implied MEMBAR #StoreStore.
