Class IntrinsicContext

java.lang.Object

com.oracle.graal.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.

Constructor Detail

IntrinsicContext

public IntrinsicContext(ResolvedJavaMethod method,
                        ResolvedJavaMethod intrinsic,
                        IntrinsicContext.CompilationContext compilationContext)

Method Detail

getOriginalMethod

public ResolvedJavaMethod getOriginalMethod()

getIntrinsicMethod

public ResolvedJavaMethod getIntrinsicMethod()

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()

isCompilationRoot

public boolean isCompilationRoot()

createFrameState

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

toString

public String toString()

Overrides:
