Pass *	createPrinterPass (raw_ostream &OS, const std::string &Banner) const override
	createPrinterPass - Get a pass that prints the Module corresponding to a CallGraph.
virtual bool	doInitialization (CallGraph &CG)
	doInitialization - This method is called before the SCC's of the program has been processed, allowing the pass to do initialization as necessary.
virtual bool	doFinalization (CallGraph &CG)
	doFinalization - This method is called after the SCC's of the program has been processed, allowing the pass to do final cleanup as necessary.
void	assignPassManager (PMStack &PMS, PassManagerType PMT) override
	Assign pass manager to manager this pass.
PassManagerType	getPotentialPassManagerType () const override
	Return what kind of Pass Manager can manage this pass.
virtual bool	doInitialization (Module &)
	doInitialization - Virtual method overridden by subclasses to do any necessary initialization before any pass is run.
virtual bool	doFinalization (Module &)
	doFinalization - Virtual method overriden by subclasses to do any necessary clean up after all passes have run.

Detailed Description

This pass is required by interprocedural register allocation.

It forces codegen to follow bottom up order on call graph.

Member Function Documentation

◆ getAnalysisUsage()

void llvm::DummyCGSCCPass::getAnalysisUsage ( AnalysisUsage & AU ) const

inlineoverridevirtual

getAnalysisUsage - For this class, we declare that we require and preserve the call graph.

For this class, we declare that we require and preserve the call graph.

If the derived class implements this method, it should always explicitly call the implementation here.

Reimplemented from llvm::CallGraphSCCPass.

Definition at line 129 of file CallGraphSCCPass.h.

References llvm::AnalysisUsage::setPreservesAll().

◆ runOnSCC()

bool llvm::DummyCGSCCPass::runOnSCC ( CallGraphSCC & SCC )

inlineoverridevirtual

runOnSCC - This method should be implemented by the subclass to perform whatever action is necessary for the specified SCC.

Note that non-recursive (or only self-recursive) functions will have an SCC size of 1, where recursive portions of the call graph will have SCC size > 1.

SCC passes that add or delete functions to the SCC are required to update the SCC list, otherwise stale pointers may be dereferenced.

Implements llvm::CallGraphSCCPass.
