Class ProxyNode

java.lang.Object

com.oracle.graal.graph.Node

com.oracle.graal.nodes.ValueNode

com.oracle.graal.nodes.calc.FloatingNode

com.oracle.graal.nodes.ProxyNode

All Implemented Interfaces:

IterableNodeType, Node.ValueNumberable, Cloneable, Formattable, KindProvider

Direct Known Subclasses:

EntryProxyNode, GuardProxyNode, ValueProxyNode

public abstract class ProxyNode
extends FloatingNode
implements IterableNodeType, Node.ValueNumberable

A proxy is inserted at loop exits for any value that is created inside the loop (i.e. was not live on entry to the loop) and is (potentially) used after the loop.
