This header provides classes for managing per-loop analyses.
This header defines various interfaces for pass management in LLVM.
A container for analyses that lazily runs them and caches their results.

This class provides an interface for updating the loop pass manager based on mutations to the loop ne...
This class represents a loop nest and can be used to query its properties.
A simple loop rotation transformation.
PreservedAnalyses run(LoopNest &L, LoopAnalysisManager &AM, LoopStandardAnalysisResults &AR, LPMUpdater &U)
A set of analyses that are preserved following a run of a transformation pass.
Definition: Analysis.h:111
This is an optimization pass for GlobalISel generic memory operations.
Definition: AddressRanges.h:18
The adaptor from a function pass to a loop pass computes these analyses and makes them available to t...
