problem with non-allocatable register classes
I am using some non-allocatable RegisterClasses to define lists of registers that are used for various non-allocation-related processing in the back end. For example, we have a post-allocation functional unit selection pass that is guided by the register assignment, which does things like 'myRegClass.contains(Reg)' to see if a register is in the set of registers accessible by a given unit.
