Class ReadRegisterFloatingNode

java.lang.Object

org.graalvm.compiler.graph.Node

org.graalvm.compiler.nodes.ValueNode

org.graalvm.compiler.nodes.calc.FloatingNode

com.oracle.svm.core.graal.nodes.ReadRegisterFloatingNode

All Implemented Interfaces:

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

Direct Known Subclasses:

ReadIsolateThreadFloatingNode

public abstract class ReadRegisterFloatingNode
extends org.graalvm.compiler.nodes.calc.FloatingNode
implements org.graalvm.compiler.nodes.spi.LIRLowerable

Reads the value of a specific register. This is a floating node that uses the register directly as the result. It is more efficient than using a ReadRegisterFixedNode, but limits usages.
