Class IntrinsicContext

java.lang.Object

org.graalvm.compiler.nodes.graphbuilderconf.IntrinsicContext

public class IntrinsicContext
extends Object

An intrinsic is a substitute implementation of a Java method (or a bytecode in the case of snippets) that is itself implemented in Java. This interface provides information about the intrinsic currently being processed by the graph builder. When in the scope of an intrinsic, the graph builder does not check the value kinds flowing through the JVM state since intrinsics can employ non-Java kinds to represent values such as raw machine words and pointers.

Method Detail

allowPartialIntrinsicArgumentMismatch

public boolean allowPartialIntrinsicArgumentMismatch()

A partial intrinsic exits by (effectively) calling the intrinsified method. Normally, this call must use exactly the same arguments as the call that is being intrinsified. This allows to override this behavior.

getOriginalMethod

public ResolvedJavaMethod getOriginalMethod()

Gets the method being intrinsified.

getIntrinsicMethod

public ResolvedJavaMethod getIntrinsicMethod()

Gets the method providing the intrinsic implementation.

getBytecodeProvider

public BytecodeProvider getBytecodeProvider()

Gets provider of bytecode to be parsed for a method that is part of an intrinsic.

isCallToOriginal

public boolean isCallToOriginal(ResolvedJavaMethod targetMethod)

Determines if a call within the compilation scope of this intrinsic represents a call to the original method. This denotes the path where a partial intrinsification falls back to the original method.

isPostParseInlined

public boolean isPostParseInlined()

getNodeSourcePosition

public NodeSourcePosition getNodeSourcePosition()

setNodeSourcePosition

public void setNodeSourcePosition(NodeSourcePosition position)

isDeferredInvoke

public boolean isDeferredInvoke(StateSplit stateSplit)

createFrameState

public FrameState createFrameState(StructuredGraph graph,
                                   IntrinsicContext.SideEffectsState sideEffects,
                                   StateSplit forStateSplit,
                                   NodeSourcePosition sourcePosition)

toString

public String toString()

Overrides:
