Member Function Documentation

◆ doFinalization()

bool PhysicalRegisterUsageInfo::doFinalization ( Module )
overridevirtual

doFinalization - Virtual method overriden by subclasses to do any necessary clean up after all passes have run.

Reimplemented from llvm::Pass.

Definition at line 52 of file RegisterUsageInfo.cpp.

References DumpRegUsage, llvm::errs(), and print().

Referenced by setTargetMachine().

◆ doInitialization()

bool PhysicalRegisterUsageInfo::doInitialization ( Module )
overridevirtual

doInitialization - Virtual method overridden by subclasses to do any necessary initialization before any pass is run.

Reimplemented from llvm::Pass.

Definition at line 47 of file RegisterUsageInfo.cpp.

References llvm::Module::size().

Referenced by setTargetMachine().

◆ getAnalysisUsage()

void llvm::PhysicalRegisterUsageInfo::getAnalysisUsage ( AnalysisUsage ) const
inlineoverridevirtual

getAnalysisUsage - This function should be overriden by passes that need analysis information to do their job.

If a pass specifies that it uses a particular analysis result to this function, it can then use the getAnalysis<AnalysisType>() function, below.

Reimplemented from llvm::Pass.

Definition at line 44 of file RegisterUsageInfo.h.

References llvm::AnalysisUsage::setPreservesAll().

◆ getRegUsageInfo()

const std::vector< uint32_t > * PhysicalRegisterUsageInfo::getRegUsageInfo ( const Function FP)

To query stored RegMask for given Function *, it will return nullptr if function is not known.

Definition at line 67 of file RegisterUsageInfo.cpp.

Referenced by findCalledFunction(), and setTargetMachine().

◆ print()

void PhysicalRegisterUsageInfo::print ( raw_ostream OS,
const Module M = nullptr 
) const
overridevirtual

print - Print out the internal state of the pass.

This is called by Analyze to print out the contents of an analysis. Otherwise it is not necessary to implement this method. Beware that the module pointer MAY be null. This automatically forwards to a virtual function that does not provide the Module* in case the analysis doesn't need it it can just be ignored.

Reimplemented from llvm::Pass.

◆ setTargetMachine()

void llvm::PhysicalRegisterUsageInfo::setTargetMachine ( const TargetMachine TM_)
inline

To set TargetMachine *, which is used to print analysis when command line option -print-regusage is used.
