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. | |

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. | |

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. | |
