The mapping from the C/C++ memory model to Ztso has not yet been ratified in any standards document.  There are multiple possible mappings, and they are *not* mutually ABI compatible.  The mapping LLVM implements is ABI compatible with the default WMO mapping.  This mapping may change and there is *explicitly* no ABI stability offered while the extension remains in experimental status.  User beware.
