Ztso Extension

The Ztso extension provides Total Store Ordering (TSO) memory consistency semantics for RISC-V systems. This is an optional extension that complements the baseline RISC-V Weak Memory Ordering (RVWMO) model by providing stricter memory ordering guarantees.

When Ztso is implemented, all loads and stores behave as if they have implicit acquire and release semantics, respectively. This provides a familiar programming model for software developed on architectures that natively support TSO, such as x86.
