Class CFunctionPrologueDataNode

java.lang.Object

org.graalvm.compiler.graph.Node

org.graalvm.compiler.nodes.ValueNode

com.oracle.svm.core.nodes.CFunctionPrologueDataNode

All Implemented Interfaces:

CPrologueData, Cloneable, Formattable, org.graalvm.compiler.nodes.spi.LIRLowerable, org.graalvm.compiler.nodes.ValueNodeInterface

public final class CFunctionPrologueDataNode
extends org.graalvm.compiler.nodes.ValueNode
implements CPrologueData, org.graalvm.compiler.nodes.spi.LIRLowerable

We use this class to transport some data from the CFunctionPrologueNode to the InvokeNode. This is necessary because the prologue of a C function is decoupled from the actual invocation of the C function even though the backend needs information about the prologue when emitting the call.
