Public Member Functions
CallGraphSCCPass (char &pid)
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 runOnSCC (CallGraphSCC &SCC)=0
runOnSCC - This method should be implemented by the subclass to perform whatever action is necessary for the specified SCC.
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.
void getAnalysisUsage (AnalysisUsage &Info) const override
getAnalysisUsage - For this class, we declare that we require and preserve the call graph.
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.

virtual ~Pass ()
PassKind getPassKind () const
virtual StringRef getPassName () const
getPassName - Return a nice clean name for a pass.
StringRef getPassArgument () const
Return a nice clean name for a pass corresponding to that used to enable the pass in opt.
AnalysisID getPassID () const
getPassID - Return the PassID number that corresponds to this pass.
virtual void print (raw_ostream &OS, const Module *M) const
print - Print out the internal state of the pass.
void dump () const
virtual void preparePassManager (PMStack &)
Check if available pass managers are suitable for this pass or not.
void setResolver (AnalysisResolver *AR)
AnalysisResolver * getResolver () const
virtual void releaseMemory ()
releaseMemory() - This member can be implemented by a pass if it wants to be able to release its memory when it is no longer needed.
virtual ImmutablePass * getAsImmutablePass ()
virtual PMDataManager * getAsPMDataManager ()
virtual void verifyAnalysis () const
verifyAnalysis() - This member can be implemented by a analysis pass to check state of analysis information.

template
AnalysisType * getAnalysisIfAvailable () const
getAnalysisIfAvailable() - Subclasses use this function to get analysis information that might be around, for example to update it.
bool mustPreserveAnalysisID (char &AID) const
mustPreserveAnalysisID - This method serves the same function as getAnalysisIfAvailable, but works if you just have an AnalysisID.

getAnalysis() - This function is used by subclasses to get to the analysis information that they claim to use by overriding the getAnalysisUsage function.
template

◆ createPrinterPass()

◆ doFinalization() [1/2]

virtual bool llvm::CallGraphSCCPass::doFinalization ( CallGraph & CG) inlinevirtual

doFinalization - This method is called after the SCC's of the program has been processed, allowing the pass to do final cleanup as necessary.

Definition at line 64 of file CallGraphSCCPass.h.

◆ doFinalization() [2/2]

virtual bool llvm::Pass::doFinalization ( Module & ) inlinevirtual

doFinalization - Virtual method overriden by subclasses to do any necessary clean up after all passes have run.

Reimplemented from llvm::Pass.

Definition at line 132 of file Pass.h.

◆ doInitialization() [1/2]

virtual bool llvm::CallGraphSCCPass::doInitialization ( CallGraph & CG) inlinevirtual

doInitialization - This method is called before the SCC's of the program has been processed, allowing the pass to do initialization as necessary.

Definition at line 49 of file CallGraphSCCPass.h.

◆ doInitialization() [2/2]

virtual bool llvm::Pass::doInitialization ( Module & ) inlinevirtual

doInitialization - Virtual method overridden by subclasses to do any necessary initialization before any pass is run.

Reimplemented from llvm::Pass.

Definition at line 128 of file Pass.h.

◆ getAnalysisUsage()

void CallGraphSCCPass::getAnalysisUsage ( AnalysisUsage & AU) const overridevirtual

◆ getPotentialPassManagerType()

PassManagerType llvm::CallGraphSCCPass::getPotentialPassManagerType ( ) const inlineoverridevirtual

◆ runOnSCC()

virtual bool llvm::CallGraphSCCPass::runOnSCC ( CallGraphSCC & SCC) pure virtual

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.

Implemented in llvm::DummyCGSCCPass.
