Declared at: llvm/include/llvm/CodeGen/LiveRangeEdit.h:46

Method Overview

• public virtual bool LRE_CanEraseVirtReg(llvm::Register)
• public virtual void LRE_DidCloneVirtReg(llvm::Register New, llvm::Register Old)
• public virtual void LRE_WillEraseInstruction(llvm::MachineInstr * MI)
• public virtual void LRE_WillShrinkVirtReg(llvm::Register)

Methods

¶virtual bool LRE_CanEraseVirtReg(llvm::Register)

Description

Called when a virtual register is no longer used. Return false to defer its deletion from LiveIntervals.

Declared at: llvm/include/llvm/CodeGen/LiveRangeEdit.h:57

Parameters

llvm::Register

¶virtual void LRE_DidCloneVirtReg(
    llvm::Register New,
    llvm::Register Old)

Description

Called after cloning a virtual register. This is used for new registers representing connected components of Old.

Declared at: llvm/include/llvm/CodeGen/LiveRangeEdit.h:64

Parameters

llvm::Register New

llvm::Register Old

¶virtual void LRE_WillEraseInstruction(
    llvm::MachineInstr* MI)

Description

Called immediately before erasing a dead machine instruction.

Declared at: llvm/include/llvm/CodeGen/LiveRangeEdit.h:53

Parameters

llvm::MachineInstr* MI

¶virtual void LRE_WillShrinkVirtReg(llvm::Register)

Description

Called before shrinking the live range of a virtual register.

Declared at: llvm/include/llvm/CodeGen/LiveRangeEdit.h:60

Parameters

llvm::Register

¶virtual void anchor()

Declared at: llvm/include/llvm/CodeGen/LiveRangeEdit.h:47

¶virtual ~Delegate()

Declared at: llvm/include/llvm/CodeGen/LiveRangeEdit.h:50
