LRE_CanEraseVirtReg()

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

inlinevirtual

Called when a virtual register is no longer used.

Return false to defer its deletion from LiveIntervals.

LRE_DidCloneVirtReg()

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

inlinevirtual

Called after cloning a virtual register.

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