This header provides classes for managing per-loop analyses.
This header defines various interfaces for pass management in LLVM.
raw_pwrite_stream & OS
A container for analyses that lazily runs them and caches their results.
Definition: PassManager.h:253
This class provides an interface for updating the loop pass manager based on mutations to the loop ne...
A simple loop rotation transformation.
Definition: LoopRotation.h:24
void printPipeline(raw_ostream &OS, function_ref< StringRef(StringRef)> MapClassName2PassName)
PreservedAnalyses run(Loop &L, LoopAnalysisManager &AM, LoopStandardAnalysisResults &AR, LPMUpdater &U)
Represents a single loop in the control flow graph.
Definition: LoopInfo.h:39
A set of analyses that are preserved following a run of a transformation pass.
Definition: Analysis.h:111
StringRef - Represent a constant reference to a string, i.e.
Definition: StringRef.h:50
An efficient, type-erasing, non-owning reference to a callable.
This class implements an extremely fast bulk output stream that can only output to a stream.
Definition: raw_ostream.h:52
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...
A CRTP mix-in to automatically provide informational APIs needed for passes.
