Methods

¶RegionInfo()

Declared at: llvm/include/llvm/Analysis/RegionInfo.h:908

¶RegionInfo(llvm::RegionInfo&& Arg)

Declared at: llvm/include/llvm/Analysis/RegionInfo.h:910

Parameters

llvm::RegionInfo&& Arg

¶bool invalidate(
    llvm::Function& F,
    const llvm::PreservedAnalyses& PA,
    FunctionAnalysisManager::Invalidator&)

Description

Handle invalidation explicitly.

Declared at: llvm/include/llvm/Analysis/RegionInfo.h:923

Parameters

llvm::Function& F

const llvm::PreservedAnalyses& PA

FunctionAnalysisManager::Invalidator&

¶void recalculate(llvm::Function& F,
                 llvm::DominatorTree* DT,
                 llvm::PostDominatorTree* PDT,
                 llvm::DominanceFrontier* DF)

Declared at: llvm/include/llvm/Analysis/RegionInfo.h:929

Parameters

llvm::Function& F

llvm::DominatorTree* DT

llvm::PostDominatorTree* PDT

llvm::DominanceFrontier* DF

¶void updateStatistics(llvm::Region* R)

Declared at: llvm/include/llvm/Analysis/RegionInfo.h:927

Parameters

llvm::Region* R

¶void view()

Description

Opens a viewer to show the GraphViz visualization of the regions. Useful during debugging as an alternative to dump().

Declared at: llvm/include/llvm/Analysis/RegionInfo.h:936

¶void viewOnly()

Description

Opens a viewer to show the GraphViz visualization of this region without instructions in the BasicBlocks. Useful during debugging as an alternative to dump().
