All Implemented Interfaces:

Cloneable, Formattable, MemoryKillMarker, SimplifiableMarker, DeoptBciSupplier, DeoptimizingNode, DeoptimizingNode.DeoptDuring, FixedNodeInterface, LoopExpandableNode, MemoryAccess, MemoryKill, SingleMemoryKill, Lowerable, NodeWithState, Simplifiable, Virtualizable, StateSplit, ValueNodeInterface

public final class ArrayCopyWithDelayedLoweringNode
extends BasicArrayCopyNode
implements Simplifiable, LoopExpandableNode

A version of BasicArrayCopyNode that delays lowering. The ArrayCopyWithDelayedLoweringNode.snippet which will be used for lowering is already known up front, but applying it is delayed to avoid unfavorable interaction with other phases (floating guards, frame state assignment, etc.).
