4// SI did not actually support flat addressing, but we can codegen the address
5// space test builtins. The target specfic part is a load from the implicit
6// argument buffer to use for the high pointer bits. It's just that buffer won't
7// be initialized to something useful. The proper way to diagnose invalid flat
8// usage is to forbid flat pointers on unsupported targets.
