PreservedAnalyses run(LazyCallGraph::SCC &C, CGSCCAnalysisManager &AM, LazyCallGraph &CG, CGSCCUpdateResult &UR)
This header provides classes for managing passes over SCCs of the call graph.
An SCC of the call graph.
A container for analyses that lazily runs them and caches their results.
This header defines various interfaces for pass management in LLVM.
