That's almost correct. MCRegisters can only be invalid ($noreg) or physical registers. The lack of support for vregs is indicated by the lack of any vreg API's while the lack of support for stack slots is indicated by the lack of all (except one) stack slot API's and is mentioned in a comment: "StackSlot values do not...
