class Legalizer

Declaration

class Legalizer : public MachineFunctionPass { /* full declaration omitted */ };

Description

MachineFunctionPass - This class adapts the FunctionPass interface to allow convenient creation of passes that operate on the MachineFunction representation. Instead of overriding runOnFunction, subclasses override runOnMachineFunction.

Methods

¶Legalizer()

Declared at: llvm/include/llvm/CodeGen/GlobalISel/Legalizer.h:45

¶bool combineExtracts(
    llvm::MachineInstr& MI,
    llvm::MachineRegisterInfo& MRI,
    const llvm::TargetInstrInfo& TII)

Declared at: llvm/include/llvm/CodeGen/GlobalISel/Legalizer.h:66

Parameters

llvm::MachineInstr& MI

llvm::MachineRegisterInfo& MRI

const llvm::TargetInstrInfo& TII

¶void getAnalysisUsage(
    llvm::AnalysisUsage& AU) const

Description

getAnalysisUsage - Subclasses that override getAnalysisUsage must call this. For MachineFunctionPasses, calling AU.preservesCFG() indicates that the pass does not modify the MachineBasicBlock CFG.

Declared at: llvm/include/llvm/CodeGen/GlobalISel/Legalizer.h:49

Parameters

llvm::AnalysisUsage& AU

¶llvm::MachineFunctionProperties
getClearedProperties() const

Declared at: llvm/include/llvm/CodeGen/GlobalISel/Legalizer.h:61

¶llvm::StringRef getPassName() const

Description

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.

Declared at: llvm/include/llvm/CodeGen/GlobalISel/Legalizer.h:47

¶llvm::MachineFunctionProperties
getRequiredProperties() const

Declared at: llvm/include/llvm/CodeGen/GlobalISel/Legalizer.h:51

¶llvm::MachineFunctionProperties getSetProperties()
    const

Declared at: llvm/include/llvm/CodeGen/GlobalISel/Legalizer.h:56

¶static llvm::Legalizer::MFResult
legalizeMachineFunction(
    llvm::MachineFunction& MF,
    const llvm::LegalizerInfo& LI,
    ArrayRef<llvm::GISelChangeObserver*>
        AuxObservers,
    llvm::MachineIRBuilder& MIRBuilder)

Declared at: llvm/include/llvm/CodeGen/GlobalISel/Legalizer.h:72

Parameters

llvm::MachineFunction& MF

const llvm::LegalizerInfo& LI

ArrayRef<llvm::GISelChangeObserver*> AuxObservers

llvm::MachineIRBuilder& MIRBuilder

¶bool runOnMachineFunction(
    llvm::MachineFunction& MF)

Description

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

Declared at: llvm/include/llvm/CodeGen/GlobalISel/Legalizer.h:69

Parameters

llvm::MachineFunction& MF
