Class GetObjectAddressNode

java.lang.Object

com.oracle.graal.graph.Node

com.oracle.graal.nodes.ValueNode

com.oracle.graal.nodes.FixedNode

com.oracle.graal.nodes.FixedWithNextNode

com.oracle.graal.hotspot.nodes.GetObjectAddressNode

All Implemented Interfaces:

LIRLowerable, Cloneable, Formattable, KindProvider

public final class GetObjectAddressNode
extends FixedWithNextNode
implements LIRLowerable

Intrinsification for getting the address of an object. The code path(s) between a call to get(Object) and all uses of the returned value must not contain safepoints. This can only be guaranteed if used in a snippet that is instantiated after frame state assignment. ComputeObjectAddressNode should generally be used in preference to this node.
