All Implemented Interfaces:

NodeInterface, NodeWithState, StateSplit, Cloneable, Formattable, KindProvider

public final class UnsafeCopyNode
extends FixedWithNextNode
implements StateSplit

Copy a value at a location specified as an offset relative to a source object to another location specified as an offset relative to destination object. No null checks are performed. This node must be replaced during processing of node intrinsics with an UnsafeLoadNode and UnsafeStoreNode pair.

sourceObject

public ValueNode sourceObject()

destinationObject

public ValueNode destinationObject()

getLocationIdentity

public LocationIdentity getLocationIdentity()

sourceOffset

public ValueNode sourceOffset()

destinationOffset

public ValueNode destinationOffset()

accessKind

public Kind accessKind()

stateAfter

public FrameState stateAfter()

Description copied from interface: StateSplit

Gets the FrameState corresponding to the state of the JVM after execution of this node.

Specified by:

stateAfter in interface StateSplit

setStateAfter

public void setStateAfter(FrameState x)

Description copied from interface: StateSplit

Sets the FrameState corresponding to the state of the JVM after execution of this node.

Specified by:

setStateAfter in interface StateSplit

hasSideEffect

public boolean hasSideEffect()

Description copied from interface: StateSplit

Determines if this node has a side-effect. Such nodes cannot be safely re-executed because they modify state which is visible to other threads or modify state beyond what is captured in FrameState nodes.

Specified by:

hasSideEffect in interface StateSplit

getState

public FrameState getState()

copy

public static void copy(Object srcObject,
                        long srcOffset,
                        Object destObject,
