...iler to automatically figure out which branches are divergent or not. However, doing that precisely is extremely hard and can be expensive. Therefore, I am proposing a compromise to have programmers provide some optimization hints. The annotation in my mind is in the format of “#pragma clang branch non_divergence”. Programmers can add this annotation right before a control statement (such as if, for, and while), indicating the branch derived from the control statement is not divergent.For example, #pragma clang branch non_divergenceif (a > 0) { …}indicates the condition (a > 0) is uniform across...
