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.

And you spoke about looping in C as well :-)
You're right! I did.

While it might be a single instruction, I'm pretty sure the number of ticks that is used up is still proportional to the length of the strings - you just can't wrap an O(n) operation in O(1) with finite hardware.
