Public Member Functions
PMDataManager ()
virtual ~PMDataManager ()
virtual Pass * getAsPass ()=0
void recordAvailableAnalysis (Pass *P)
Augment AvailableAnalysis by adding analysis made available by pass P.
void verifyPreservedAnalysis (Pass *P)
verifyPreservedAnalysis – Verify analysis presreved by pass P.
void removeNotPreservedAnalysis (Pass *P)
Remove Analysis that is not preserved by the pass.
void removeDeadPasses (Pass *P, StringRef Msg, enum PassDebuggingString)
Remove dead passes used by P.
void freePass (Pass *P, StringRef Msg, enum PassDebuggingString)
Remove P.
void add (Pass *P, bool ProcessAnalysis=true)
Add pass P into the PassVector.
virtual void addLowerLevelRequiredPass (Pass *P, Pass *RequiredPass)
Add RequiredPass into list of lower level passes required by pass P.
virtual std::tuple< Pass *, bool > getOnTheFlyPass (Pass *P, AnalysisID PI, Function &F)
void initializeAnalysisInfo ()
Initialize available analysis information.
bool preserveHigherLevelAnalysis (Pass *P)
void collectRequiredAndUsedAnalyses (SmallVectorImpl< Pass * > &UsedPasses, SmallVectorImpl< AnalysisID > &ReqPassNotAvailable, Pass *P)
Populate UsedPasses with analysis pass that are used or required by pass P and are available.
void initializeAnalysisImpl (Pass *P)
All Required analyses should be available to the pass as it runs! Here we fill in the AnalysisImpls member of the pass so that it can successfully use the getAnalysis() method to retrieve the implementations it needs.
Pass * findAnalysisPass (AnalysisID AID, bool Direction)
Find the pass that implements Analysis AID.

DenseMap< AnalysisID, Pass * > * getAvailableAnalysis ()
void populateInheritedAnalysis (PMStack &PMS)
unsigned initSizeRemarkInfo (Module &M, StringMap< std::pair< unsigned, unsigned > > &FunctionToInstrCount)
Set the initial size of the module if the user has specified that they want remarks for size.
void emitInstrCountChangedRemark (Pass *P, Module &M, int64_t Delta, unsigned CountBefore, StringMap< std::pair< unsigned, unsigned > > &FunctionToInstrCount, Function *F=nullptr)
Emit a remark signifying that the number of IR instructions in the module changed.
