Hi all, Does anyone know how to recreate the DominanceFronter and PostDominanceFrontier structures using the API of the latest release? To my knowledge, these are needed to implement a PRE pass (as done in the past<https://llvm.org/svn/llvm-project/llvm/tags/RELEASE_13/lib/Transforms/Scalar/PRE.cpp>), but they were removed a while ago for efficiency r...

...be represented by some integers) o. step 3 is nothing as normally a block only have two immediate succ. Again this algorithm is just random idea. It is at your own risk if you try it.
