Member Function Documentation

getAnalysisUsage()

void IRTranslator::getAnalysisUsage ( AnalysisUsage &  ) const

overridevirtual

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 171 of file IRTranslator.cpp.

References llvm::AnalysisUsage::addPreserved(), llvm::AnalysisUsage::addRequired(), llvm::MachineFunctionPass::getAnalysisUsage(), llvm::getSelectionDAGFallbackAnalysisUsage(), and llvm::None.

getPassName()

StringRef llvm::IRTranslator::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.

Definition at line 721 of file IRTranslator.h.

runOnMachineFunction()

bool IRTranslator::runOnMachineFunction ( MachineFunction &  MF )

overridevirtual

runOnMachineFunction - This method must be overloaded to perform the desired machine code transformation or analysis.

Implements llvm::MachineFunctionPass.
