Hi Rask, Basically the CPU has the 'SCALE_28_4' instruction which does the following: output = (operand1 >> 28) | (operand2 << 4)
From my understanding the OR operation (ior), doesn't get canonicalized since it's second operand (in this case (lshiftrt:SI (match_operand:SI 2 "register_operand" "r") (const_int 4)) ) is not a constant.
