#83208 - optimiser Responding to: ???'s previous message |
But cntr_1 and cntr_2 variables are very much part of my Delay routine and how do you say they are never used ? But the only thing they are used for is as loop counters - the loops do nothing, and the counters are not used after the loops finish. Thus, in terms of any observable effects outside the delay function (or even outside the loops), they do nothing. Therefore the optimiser could legitimately remove them. Adding 'volatile' will not cost you anything, but will certainly ensure that you don't lose anything! |
