Member Function Documentation

LRE_CanEraseVirtReg()

virtual bool llvm::LiveRangeEdit::Delegate::LRE_CanEraseVirtReg ( unsigned  )

inlinevirtual

Called when a virtual register is no longer used.

Return false to defer its deletion from LiveIntervals.

Definition at line 60 of file LiveRangeEdit.h.

LRE_DidCloneVirtReg()

virtual void llvm::LiveRangeEdit::Delegate::LRE_DidCloneVirtReg ( unsigned  New, unsigned  Old  )

inlinevirtual

Called after cloning a virtual register.

This is used for new registers representing connected components of Old.

Definition at line 67 of file LiveRangeEdit.h.

LRE_WillEraseInstruction()

virtual void llvm::LiveRangeEdit::Delegate::LRE_WillEraseInstruction ( MachineInstr *  MI )

inlinevirtual

Called immediately before erasing a dead machine instruction.

Definition at line 56 of file LiveRangeEdit.h.

LRE_WillShrinkVirtReg()

virtual void llvm::LiveRangeEdit::Delegate::LRE_WillShrinkVirtReg ( unsigned  )

inlinevirtual

Called before shrinking the live range of a virtual register.
