ModuleAnalysisManager MAM

A Module instance is used to store all the information related to an LLVM module.

A set of analyses that are preserved following a run of a transformation pass.

static PreservedAnalyses all()

Construct a special preserved set that preserves all passes.

PreservedAnalyses run(Module &M, ModuleAnalysisManager &MAM)
