Class AbstractDeoptimizeNode

java.lang.Object

com.oracle.graal.graph.Node

com.oracle.graal.nodes.ValueNode

com.oracle.graal.nodes.FixedNode

com.oracle.graal.nodes.ControlSinkNode

com.oracle.graal.nodes.AbstractDeoptimizeNode

All Implemented Interfaces:

IterableNodeType, NodeInterface, DeoptimizingNode, DeoptimizingNode.DeoptBefore, NodeWithState, Cloneable, Formattable, KindProvider

Direct Known Subclasses:

DeoptimizeNode, DynamicDeoptimizeNode

public abstract class AbstractDeoptimizeNode
extends ControlSinkNode
implements IterableNodeType, DeoptimizingNode.DeoptBefore

This node represents an unconditional explicit request for immediate deoptimization. After this node, execution will continue using a fallback execution engine (such as an interpreter) at the position described by the deoptimization state.
