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.
Definition: PassManager.h:239
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:109
@ 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...
