Public Member Functions
Localizer ()
Localizer (std::function< bool(const MachineFunction &)>)
getPassName () const override
getPassName - Return a nice clean name for a pass.
getRequiredProperties () const override
void
getAnalysisUsage (AnalysisUsage &AU) const override
getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job.
runOnMachineFunction (MachineFunction &MF) override
runOnMachineFunction - This method must be overloaded to perform the desired machine code transformation or analysis.
Public Member Functions inherited from llvm::MachineFunctionPass
doInitialization (Module &) override
doInitialization - Virtual method overridden by subclasses to do any necessary initialization before any pass is run.
Public Member Functions inherited from llvm::FunctionPass
FunctionPass (char &pid)
Pass *
createPrinterPass (raw_ostream &OS, const std::string &Banner) const override
createPrinterPass - Get a function printer pass.
virtual bool
runOnFunction (Function &F)=0
runOnFunction - Virtual method overriden by subclasses to do the per-function processing of the pass.
void
assignPassManager (PMStack &PMS, PassManagerType T) override
Find appropriate Function Pass Manager or Call Graph Pass Manager in the PM Stack and add self into that manager.
getPotentialPassManagerType () const override
Return what kind of Pass Manager can manage this pass.

~Pass ()
getPassKind () const
virtual StringRef
getPassName () const
getPassName - Return a nice clean name for a pass.
getPassID - Return the PassID number that corresponds to this pass.
virtual bool
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
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)
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() - 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 *
virtual PMDataManager *
virtual void
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.
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.

AnalysisType &
getAnalysisID (AnalysisID PI, Function &F, bool *Changed=nullptr)
This pass implements the localization mechanism described at the top of this file.
One specificity of the implementation is that it will materialize one and only one instance of a constant per basic block, thus enabling reuse of that constant within that block. Moreover, it only materializes constants in blocks where they are used. PHI uses are considered happening at the end of the related predecessor.
