Some CISC processors include string operators so the XOR might actually be a single instruction.
They still loop, just at the microcode level.
There is always a conditional test; address register(s) get incremented; and often a count register gets decremented; for some number of repetitions or until some condition is met. It's still a 'loop' by any standard.
