Member Function Documentation

◆ getAnalysisUsage()

void RegBankSelectLegacy::getAnalysisUsage ( AnalysisUsage & AU ) const

overridevirtual

getAnalysisUsage - Subclasses that override getAnalysisUsage must call this.

For MachineFunctionPasses, calling AU.preservesCFG() indicates that the pass does not modify the MachineBasicBlock CFG.

Reimplemented from llvm::MachineFunctionPass.

Definition at line 711 of file RegBankSelect.cpp.

References llvm::AnalysisUsage::addRequired(), llvm::Fast, llvm::MachineFunctionPass::getAnalysisUsage(), and llvm::getSelectionDAGFallbackAnalysisUsage().

◆ getClearedProperties()

MachineFunctionProperties llvm::RegBankSelectLegacy::getClearedProperties ( ) const

inlineoverridevirtual

Reimplemented from llvm::MachineFunctionPass.

Definition at line 108 of file RegBankSelect.h.

◆ getPassName()

StringRef llvm::RegBankSelectLegacy::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 96 of file RegBankSelect.h.

◆ getRequiredProperties()

MachineFunctionProperties llvm::RegBankSelectLegacy::getRequiredProperties ( ) const

inlineoverridevirtual

Reimplemented from llvm::MachineFunctionPass.

Definition at line 100 of file RegBankSelect.h.

◆ getSetProperties()

MachineFunctionProperties llvm::RegBankSelectLegacy::getSetProperties ( ) const

inlineoverridevirtual

Reimplemented from llvm::MachineFunctionPass.

Definition at line 104 of file RegBankSelect.h.

◆ runOnMachineFunction()

bool RegBankSelectLegacy::runOnMachineFunction ( MachineFunction & MF )

overridevirtual

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

Implements llvm::MachineFunctionPass.

Definition at line 1759 of file RegBankSelect.cpp.

References llvm::Pass::getAnalysis(), and llvm::Pass::getAnalysisIfAvailable().
