public final class ArrayCopyNode
extends BasicArrayCopyNode
implements Lowerable

This node intrinsifies System.arraycopy(java.lang.Object, int, java.lang.Object, int, int). Lowering is implemented in the platform/VM specific LoweringProvider. Most of them eventually go through ArrayCopySnippets.Templates.lower(ArrayCopyNode, boolean, org.graalvm.compiler.nodes.spi.LoweringTool).

Method Detail

getKilledLocationIdentity

public org.graalvm.word.LocationIdentity getKilledLocationIdentity()

Description copied from interface: SingleMemoryKill

This method is used to determine which memory location is killed by this node. Returning the special value LocationIdentity.any() will kill all memory locations.

Specified by:

getKilledLocationIdentity in interface SingleMemoryKill

Overrides:

getKilledLocationIdentity in class BasicArrayCopyNode

Returns:

the identity of the location killed by this node.

killsAnyLocation

public boolean killsAnyLocation()
