* 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.
