WebLOOPZ/LOOPE decrements CX and jumps to the location specified in the target operand if CX is not 0 and the Zero flag ZF is 1. Otherwise, execution falls through to the next instruction. What this means is that the loop is pretty much controlled by ZF. If ZF remains 1, the loop is looped until CX is decremented to 0. WebPerforms a loop operation using the ECX or CX register as a counter. Each time the LOOP instruction is executed, the count register is decremented, then checked for 0. If the …

This document was uploaded by user and they confirmed that they have the permission … WebThese instructions automatically decrement the ECX register before testing ECX and ZF for the branch conditions. If ECX is non-zero and ZF=1, the program branches to the target label specified in the instruction. If LOOPE or LOOPZ finds that ECX=0 or ZF=0, control transfers to the instruction immediately following the LOOPE or LOOPZ instruction. ls-k901 レビュー
