Currently I'm attempting to describe the 8-bit PRU subregisters as the "real" target register set, and then work on defining 16-bit and 32-bit ALU operations. But I'm not sure if that would be efficient for a 32-bit PRU target, or feasible at all.
this is what occurred to me as the way to go. Some existing targets do the moral equivalent of that to hold a 64-bit double in an even/odd pair of 32 bit regs. Don't think there's one that's quite as extreme as what you describe.
