The patch simply passes the destination address space through
to MODE_CODE_BASE_REG_CLASS and REGNO_MODE_CODE_OK_FOR_BASE_P,
to allow targets to make register allocation decisions based
on address space.
As long as m32c doesn't implement those, just applying the
patch wouldn't change anything. But if that capability
*would* be helpful on your target, it would certainly be
good if you could try it out ...
