class RegBankSelect::RepairingPlacement

Declaration

class RegBankSelect::RepairingPlacement { /* full declaration omitted */ };

Description

Struct used to represent the placement of a repairing point for a given operand.

Declared at: llvm/include/llvm/CodeGen/GlobalISel/RegBankSelect.h:314

Member Variables

private llvm::RegBankSelect::RepairingPlacement:: RepairingKind Kind

Kind of repairing.

private unsigned int OpIdx

Index of the operand that will be repaired.

private bool CanMaterialize

Are all the insert points materializeable?

private bool HasSplit = false

Is there any of the insert points needing splitting?

private llvm::RegBankSelect::RepairingPlacement:: InsertionPoints InsertPoints

Insertion point for the repair code. The repairing code needs to happen just before these points.

private llvm::Pass& P

Some insertion points may need to update the liveness and such.

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.

Parameters

llvm::MachineInstr& MI

unsigned int OpIdx

const llvm::TargetRegisterInfo& TRI

llvm::Pass& P

¶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:371

Parameters

¶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.

Parameters

llvm::RegBankSelect::RepairingPlacement:: RepairingKind NewKind
