Public Member Functions
LoopPass (char &pid)
Pass * createPrinterPass (raw_ostream &O, const std::string &Banner) const override
getPrinterPass - Get a pass to print the function corresponding to a Loop.
virtual bool runOnLoop (Loop *L, LPPassManager &LPM)=0
virtual bool doInitialization (Loop *L, LPPassManager &LPM)
virtual bool doFinalization ()
void preparePassManager (PMStack &PMS) override
Check if available pass managers are suitable for this pass or not.
void assignPassManager (PMStack &PMS, PassManagerType PMT) override
Assign pass manager to manage 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.

Pass (PassKind K, char &pid)
Pass (const Pass &)=delete
Pass & operator= (const Pass &)=delete
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
void setResolver (AnalysisResolver *AR)
AnalysisResolver * getResolver () const
virtual void getAnalysisUsage (AnalysisUsage &) const
getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job.
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.
virtual void dumpPassStructure (unsigned Offset=0)
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.
template
AnalysisType & getAnalysis () const
getAnalysis() - This function is used by subclasses to get to the analysis information that they claim to use by overriding the getAnalysisUsage function.
template
AnalysisType & getAnalysis (Function &F, bool *Changed=nullptr)
getAnalysis() - This function is used by subclasses to get to the analysis information that they claim to use by overriding the getAnalysisUsage function.
template
AnalysisType & getAnalysisID (AnalysisID PI) const
template
AnalysisType & getAnalysisID (AnalysisID PI, Function &F, bool *Changed=nullptr)
Protected Member Functions
bool skipLoop (const Loop *L) const
Optional passes call this function to check whether the pass should be skipped.
