...ical 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 exist in the MC layer, see Register::isStackSlot() for the more information on them."
The reason there's still an MCRegister::isStackSlot() function despite that is an implementation detail. The checks for invalid and phys reg historically tested for ==0 and >0 respectively. At the same time conversion from Register to unsigned/MCReg...

What happens in that case to the
