Hi Sankaran, I hope you don't mean that the compiler won't generate software pipeline when it doesn't know the number of times the loop will iterate? If yes, then you are certainly wrong. I have lots of code where the loop count(trip count) is not explicitly defined or known beforehand, but the compiler still generates software pipline. Yong, I think that your original guess is almost certainly right. It is impossible for the compiler to generate software pipeline in case of branching withing the loop. I you are coding in linear asm, try using condition execution instead if possible.
