LLVM_ABI ExternalAAWrapperPass ()
LLVM_ABI ExternalAAWrapperPass (CallbackT CB, bool RunEarly=false)
void getAnalysisUsage (AnalysisUsage &AU) const override
getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job.
Public Member Functions inherited from llvm::ImmutablePass
ImmutablePass (char &pid)
~ImmutablePass () override
virtual void initializePass ()
initializePass - This method may be overriden by immutable passes to allow them to perform various initialization actions they require.
ImmutablePass * getAsImmutablePass () override
bool runOnModule (Module &) override
ImmutablePasses are never run.
Public Member Functions inherited from llvm::ModulePass
ModulePass (char &pid)
~ModulePass () override
Pass * createPrinterPass (raw_ostream &OS, const std::string &Banner) const override
createPrinterPass - Get a module printer pass.
void assignPassManager (PMStack &PMS, PassManagerType T) override
Find appropriate Module Pass Manager in the PM Stack and add self into that manager.
PassManagerType getPotentialPassManagerType () const override
Return what kind of Pass Manager can manage this 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.
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 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 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 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)
Public Attributes

bool RunEarly = false
Flag indicating whether this external AA should run before Basic AA.

A wrapper pass for external alias analyses.

This just squirrels away the callback used to run any analyses and register their results.

◆ ID

◆ RunEarly

bool llvm::ExternalAAWrapperPass::RunEarly = false

Flag indicating whether this external AA should run before Basic AA.

This flag is for LegacyPassManager only. To run an external AA early with the NewPassManager, override the registerEarlyDefaultAliasAnalyses method on the target machine.

By default, external AA passes are run after Basic AA. If this flag is set to true, the external AA will be run before Basic AA during alias analysis.

For some targets, we prefer to run the external AA early to improve compile time as it has more target-specific information. This is particularly useful when the external AA can provide more precise results than Basic AA so that Basic AA does not need to spend time recomputing them.
