Public Member Functions
Localizer ()
Localizer (std::function< bool(const MachineFunction &)>)
StringRef getPassName () const override
getPassName - Return a nice clean name for a pass.
MachineFunctionProperties 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.
bool 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
bool 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)
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.
PassManagerType getPotentialPassManagerType () const override
Return what kind of Pass Manager can manage this pass.
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
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 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 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
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)

bool skipFunction (const Function &F) const
Optional passes call this function to check whether the pass should be skipped.

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.

StringRef llvm::Localizer::getPassName ( ) const inlineoverridevirtual

getPassName - Return a nice clean name for a pass.

This usually implemented in terms of the name that is registered by one of the Registration templates, but can be overloaded directly.

Reimplemented from llvm::Pass.
