Class FloatingWordCastNode

org.graalvm.compiler.graph.Node

org.graalvm.compiler.nodes.ValueNode

org.graalvm.compiler.nodes.calc.FloatingNode

com.oracle.svm.core.graal.nodes.FloatingWordCastNode

All Implemented Interfaces:

Cloneable, Formattable, org.graalvm.compiler.graph.Node.ValueNumberable, org.graalvm.compiler.graph.NodeInterface, org.graalvm.compiler.graph.spi.Canonicalizable, org.graalvm.compiler.nodes.spi.LIRLowerable, org.graalvm.compiler.nodes.ValueNodeInterface

public final class FloatingWordCastNode
extends org.graalvm.compiler.nodes.calc.FloatingNode
implements org.graalvm.compiler.nodes.spi.LIRLowerable, org.graalvm.compiler.graph.spi.Canonicalizable

Cast between Word and Object that is floating. This is highly unsafe, because the scheduler can place this node anywhere. The input must therefore be a non-movable object, e.g., an object on the native image heap.
