Description

Mark the start of a TSX (HLE/RTM) suspend load address tracking region. If this is used inside a transactional region, subsequent loads are not added to the read set of the transaction. If this is used inside a suspend load address tracking region it will cause transaction abort. If this is used outside of a transactional region it behaves like a NOP.
