You need a way to type the lock semantics by memory region, and a working hardware solution can not perform as well as a careful software solution. As was pointed out earlier, you can't use memory type attributes to infer lock semantics, you must assume them in the decoder or implement complex deadlock detection and recovery in silicon.

Sure you can. You just have to be prepared to take a microop exception if you speculate incorrectly.
