WebPerforms a loop operation using the RCX, ECX or CX register as a counter (depending on whether address size is 64 bits, 32 bits, or 16 bits). Note that the LOOP instruction ignores REX.W; but 64-bit address size can be over-ridden using a 67H prefix. Each time the LOOP instruction is executed, the count register is decremented, then checked for 0. WebLike if statements, loops in assembly are also implemented using jump instructions. However, loops enable instructions to be revisited based on the result of an evaluated condition. The sumUp function shown in the following example sums up all the positive integers from 1 to a user-defined integer.
