Ah, sorry Jim, I already had a patch. Ramana pointed out this bug but I didn't
expect anyone else to actually investigate it. The overflow case can only occur
in a failure case if the operand can't be renamed, so I've chosen to just
record that fact.
Someone might want to take a look at the aarch64 backend to see if it needs to
take the new "failed" bit into account.
