## loop

    rip = dest if rcx is not 0

The loop instruction decrements rcx and transfers control (modifies rip) to the location specified by its single operand if rcx is not 0 after the decrement. The only choice is for the destination to be an 8 bit rip-relative offset. For this reason it can only be used for moderate sized loops.

mov ecx, 100 ; set rcx to 100 loop_top: ... loop loop_top ; loop executes 100 times
