A container for analyses that lazily runs them and caches their results.
Run instruction simplification across each instruction in the function.
PreservedAnalyses run(Function &F, FunctionAnalysisManager &AM)
A set of analyses that are preserved following a run of a transformation pass.
This is an optimization pass for GlobalISel generic memory operations.
A CRTP mix-in to automatically provide informational APIs needed for passes.
