[llvm-dev] Let CallGraphSCCPass Use Function-Level Analysis

Dear all,

I would like to use the PostDominatorTree in ArgPromotion. I did not find an example of how to use function level analysis inside CallGraphSCCPass. I tried to follow an example of how to use function-level pass in a module pass, but I hit "llvm_unreachable" in PMDataManager::addLowerLevelRequiredPass.

What would be a proper way to make PostDominatorTree available in ArgPromotion?

Thanks in advance,
