This header provides classes for managing passes over SCCs of the call graph.
Implements a lazy call graph analysis and related passes for the new pass manager.
This header defines various interfaces for pass management in LLVM.
A container for analyses that lazily runs them and caches their results.

Argument promotion pass.
ArgumentPromotionPass(unsigned MaxElements=2u)
PreservedAnalyses run(LazyCallGraph::SCC &C, CGSCCAnalysisManager &AM, LazyCallGraph &CG, CGSCCUpdateResult &UR)
An SCC of the call graph.
A lazily constructed view of the call graph of a module.
A set of analyses that are preserved following a run of a transformation pass.
Definition: Analysis.h:111
@ C
The default llvm calling convention, compatible with C.
Definition: CallingConv.h:34
This is an optimization pass for GlobalISel generic memory operations.
Definition: AddressRanges.h:18
Support structure for SCC passes to communicate updates the call graph back to the CGSCC pass manager...
A CRTP mix-in to automatically provide informational APIs needed for passes.
