Hi! As the title suggests, I'd like to generalize llvm::IDFCalculator to be able to calculate control dependencies on clang's CFG. The issue is however, that many data structures it uses are "hardcoded" to use llvm::BasicBlock, and requires a lot of code to turn it into template arguments. I managed to pull this off by hammering the code until it compi...

Some question: 1. IDFCalculator already allows reverse graphs, and gets used for that, so what did you have to change? (this change was made in the past year, so i wonder if you were working on a branch or something). 2. What are the actual numbers here in terms of calculation of IDF vs your method. IDF calculator is linear ti...
