Loop in Intel x86 Assembly going on forever

Question

I\'m currently learning Intel x86 Assembly, and I\'ve run into a problem while trying to construct a simple loop, which loops 10 times. It\'s supposed to stop after the 10 l

Answer 1

If the "overwriting"-problem is solved and if we are begining with a counter of 10 for decreasing the counter each circuit and if we branch if the value of the counter is greater or equal than 0, then we become a looping of 11 times.

Alternativly we can also use the zeroflag to branch (if the zeroflag is not set):

                dec     cl
                jnz     _loop_start

The "dec" instruction already involve the flag register, so we do not need the "cmp"-instruction, if we want to check if a value was decreasing to zero.
