It is part of JEP 295: Ahead-of-Time Compilation


This is formal review request for integration Graal-core sources into 
OpenJDK. AOT compiler uses Graal-core as backend compiler. We need to 
integrated Graal-core sources into JDK and add build changes to build 
Graal module.

Note, changes are based on latest jdk9/hs sources which do not have 
latest jigsaw update yet. With jigsaw update small changes will be done 
to module-info.java.extra in java.base:

   exports jdk.internal.misc to jdk.vm.compiler;
+ opens jdk.internal.misc to jdk.vm.compiler;

- exports com.sun.crypto.provider to jdk.vm.compiler;
+ opens com.sun.crypto.provider to jdk.vm.compiler;

And changes in top make/GensrcModuleInfo.gmk will not be needed.

Graal is a dynamic compiler written in Java that integrates with the 
HotSpot JVM. It has a focus on high performance and extensibility. In 
addition, it provides optimized performance for Truffle based languages 
running on the JVM.


Oracle Labs is developing and maintaining it.
