Hi, all. I'm using void LoopBase::getExitBlocks (SmallVectorImpl< BlockT * > &ExitBlocks) const to get all exit blocks for a loop. The problem I find with this API is that it returns repetitive basic blocks in certain situations. Should repetitive basic blocks be removed? I have an example to show the problem. Following is the source code and the CFG is enclosed. int main() { int

...ered and iteration order needs to be reproducible. We would need to keep a SmallPtrSet for membership checking while populating the result vector. -Andy -------------- next part -------------- An HTML attachment was scrubbed...
