What is the status of this issue? There still appears to be excessive loop unrolling even when it does not enable other optimizations.
What can I do to draw attention to this important issue? Nothing has happened for three years. I have made a comparison of different x86 compilers and tested how well...
@davidbolvansky: No, a heuristic that calculates the advantage of unrolling. If there is no significant advantage in unrolling beyond the max vector size, then don't.
@davidbolvansky. Many test cases and benchmarks tend to focus on a single loop without considering how cache use affects other parts of a code. If you test one loop in...
