Methods

¶DOTGraphTraitsViewer<AnalysisT,
                     IsSimple,
                     GraphT,
                     AnalysisGraphTraitsT>(
    llvm::StringRef GraphName)

Declared at: llvm/include/llvm/Analysis/DOTGraphTraitsPass.h:46

Parameters

llvm::StringRef GraphName

¶virtual bool processFunction(
    llvm::Function& F,
    const typename AnalysisT::Result& Result)

Description

Return true if this function should be processed. An implementation of this class my override this function to indicate that only certain functions should be viewed.

Declared at: llvm/include/llvm/Analysis/DOTGraphTraitsPass.h:54

Parameters

llvm::Function& F

const typename AnalysisT::Result& Result

The current analysis result for this function.

¶llvm::PreservedAnalyses run(
    llvm::Function& F,
    llvm::FunctionAnalysisManager& FAM)

Declared at: llvm/include/llvm/Analysis/DOTGraphTraitsPass.h:59

Parameters

llvm::Function& F

llvm::FunctionAnalysisManager& FAM

¶~DOTGraphTraitsViewer<AnalysisT,
                      IsSimple,
                      GraphT,
                      AnalysisGraphTraitsT>()

Description

Avoid compiler warning "has virtual functions but non-virtual destructor [-Wnon-virtual-dtor]" in derived classes. DOTGraphTraitsViewer is also used as a mixin for avoiding repeated implementation of viewer passes, ie there should be no runtime-polymorphisms/downcasting involving this class and hence no virtual destructor needed. Making this dtor protected stops accidental invocation when the derived class destructor should have been called. Those derived classes sould be marked final to avoid the warning.
