Public Member Functions inherited from llvm::Pass | |
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. | |
AnalysisID | getPassID () const |
getPassID - Return the PassID number that corresponds to 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. | |
virtual void | print (raw_ostream &OS, const Module *M) const |
print - Print out the internal state of the pass. | |
void | dump () const |
virtual Pass * | createPrinterPass (raw_ostream &OS, const std::string &Banner) const =0 |
createPrinterPass - Get a Pass appropriate to print the IR this pass operates on (Module, Function or MachineFunction). | |
virtual void | assignPassManager (PMStack &, PassManagerType) |
Each pass is responsible for assigning a pass manager to itself. | |
virtual void | preparePassManager (PMStack &) |
Check if available pass managers are suitable for this pass or not. | |
virtual PassManagerType | getPotentialPassManagerType () const |
Return what kind of Pass Manager can manage this pass. | |
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 void * | getAdjustedAnalysisPointer (AnalysisID ID) |
getAdjustedAnalysisPointer - This method is used when a pass implements an analysis interface through multiple inheritance. | |
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<typename AnalysisType > | |
AnalysisType * | getAnalysisIfAvailable () const |
getAnalysisIfAvailable<AnalysisType>() - 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<typename AnalysisType > | |
AnalysisType & | getAnalysis () const |
getAnalysis<AnalysisType>() - This function is used by subclasses to get to the analysis information that they claim to use by overriding the getAnalysisUsage function. | |
template<typename AnalysisType > | |
AnalysisType & | getAnalysis (Function &F, bool *Changed=nullptr) |
getAnalysis<AnalysisType>() - This function is used by subclasses to get to the analysis information that they claim to use by overriding the getAnalysisUsage function. | |
