Class UnimplementedGraalIntrinsics

java.lang.Object

org.graalvm.compiler.hotspot.meta.UnimplementedGraalIntrinsics

public final class UnimplementedGraalIntrinsics
extends Object

This class documents unimplemented Graal intrinsics and categorizes them into 3 categories:

• ignore: intrinsics that will never be implemented by Graal;
• downStream: intrinsics implemented in downstream;
• toBeInvestigated: intrinsics that yet to be implemented or moved to ignore.

Field Summary

Fields

Modifier and Type	Field and Description
Set<String>	enterprise The HotSpot intrinsics implemented in GraalVM enterprise edition.
Set<String>	ignore The HotSpot intrinsics that: will never be implemented by Graal (comments must explain why) are implemented without InvocationPlugins, or whose InvocationPlugin registration is guarded by a condition that is false in the current VM context.
Set<String>	toBeInvestigated The HotSpot intrinsics yet to be implemented or moved to UnimplementedGraalIntrinsics.ignore.

Method Summary

Modifier and Type	Method and Description
boolean	isDocumented(String method) Test if the given intrinsic candidate is documented in this file.
boolean	isIgnored(String method) Test if the given intrinsic candidate is in the UnimplementedGraalIntrinsics.ignore category -- it will not be implemented in Graal.
boolean	isImplementedInEnterprise(String method) Test if the given intrinsic candidate is in the UnimplementedGraalIntrinsics.enterprise category -- its Graal intrinsic is implemented in GraalVM EE.
boolean	isMissing(String method) Test if the given intrinsic candidate is in the UnimplementedGraalIntrinsics.toBeInvestigated category -- it may be a performance improvement opportunity and yet to be implemented.
