Methods

¶RepairingPlacement(
    llvm::MachineInstr& MI,
    unsigned int OpIdx,
    const llvm::TargetRegisterInfo& TRI,
    llvm::Pass& P,
    llvm::RegBankSelect::RepairingPlacement::
        RepairingKind Kind =
            RepairingKind::Insert)

Description

Create a repairing placement for the \p OpIdx-th operand of\p MI. \p TRI is used to make some checks on the register aliases if the machine operand is a physical register. \p P is used to to update liveness information and such when materializing the points.

Declared at: llvm/include/llvm/CodeGen/GlobalISel/RegBankSelect.h:355

Parameters

llvm::MachineInstr& MI

unsigned int OpIdx

const llvm::TargetRegisterInfo& TRI

llvm::Pass& P

llvm::RegBankSelect::RepairingPlacement:: RepairingKind Kind = RepairingKind::Insert

¶void addInsertPoint(llvm::MachineBasicBlock& MBB,
                    bool Beginning)

Description

@ { Add a MBBInsertionPoint to the list of InsertPoints.

Declared at: llvm/include/llvm/CodeGen/GlobalISel/RegBankSelect.h:370

Parameters

llvm::MachineBasicBlock& MBB

bool Beginning

¶void addInsertPoint(llvm::MachineInstr& MI,
                    bool Before)

Description

Add a InstrInsertionPoint to the list of InsertPoints.

Declared at: llvm/include/llvm/CodeGen/GlobalISel/RegBankSelect.h:372

Parameters

llvm::MachineInstr& MI

bool Before

¶void addInsertPoint(llvm::MachineBasicBlock& Src,
                    llvm::MachineBasicBlock& Dst)

Description

Add an EdgeInsertionPoint (\p Src, \p Dst) to the list of InsertPoints.

Declared at: llvm/include/llvm/CodeGen/GlobalISel/RegBankSelect.h:374

Parameters

llvm::MachineBasicBlock& Src

llvm::MachineBasicBlock& Dst

¶void addInsertPoint(
    llvm::RegBankSelect::InsertPoint& Point)

Description

Add an InsertPoint to the list of insert points. This method takes the ownership of &\p Point.

Declared at: llvm/include/llvm/CodeGen/GlobalISel/RegBankSelect.h:377

Parameters

llvm::RegBankSelect::InsertPoint& Point

¶int begin()

¶unsigned int getNumInsertPoints() const

Declared at: llvm/include/llvm/CodeGen/GlobalISel/RegBankSelect.h:388

¶unsigned int getOpIdx() const

Declared at: llvm/include/llvm/CodeGen/GlobalISel/RegBankSelect.h:362

¶bool hasSplit()

Declared at: llvm/include/llvm/CodeGen/GlobalISel/RegBankSelect.h:364

¶void switchTo(
    llvm::RegBankSelect::RepairingPlacement::
        RepairingKind NewKind)

Description

Change the type of this repairing placement to \p NewKind. It is not possible to switch a repairing placement to the RepairingKind::Insert. There is no fundamental problem with that, but no uses as well, so do not support it for now.

Declared at: llvm/include/llvm/CodeGen/GlobalISel/RegBankSelect.h:398

Parameters

llvm::RegBankSelect::RepairingPlacement:: RepairingKind NewKind
