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:253
An SCC of the call graph.
A lazily constructed view of the call graph of a module.
A Module instance is used to store all the information related to an LLVM module.
Definition: Module.h:65

Definition: OpenMPOpt.cpp:5829
OpenMPOptCGSCCPass(ThinOrFullLTOPhase LTOPhase)

PreservedAnalyses run(Module &M, ModuleAnalysisManager &AM)
Definition: OpenMPOpt.cpp:5716
A set of analyses that are preserved following a run of a transformation pass.
Definition: Analysis.h:111
A vector that has set insertion semantics.
Definition: SetVector.h:57
@ C
The default llvm calling convention, compatible with C.

bool isOpenMPDevice(Module &M)
Helper to determine if M is a OpenMP target offloading device module.
Definition: OpenMPOpt.cpp:5944
bool containsOpenMP(Module &M)
Helper to determine if M contains OpenMP.

KernelSet getDeviceKernels(Module &M)
Get OpenMP device kernels in M.
Definition: OpenMPOpt.cpp:5904
bool isOpenMPKernel(Function &Fn)
Return true iff Fn is an OpenMP GPU kernel; Fn has the "kernel" attribute.
Definition: OpenMPOpt.cpp:5900
This is an optimization pass for GlobalISel generic memory operations.
Definition: AddressRanges.h:18
ThinOrFullLTOPhase
This enumerates the LLVM full LTO or ThinLTO optimization phases.
Definition: Pass.h:76
@ None
No LTO/ThinLTO behavior needed.
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.
