Substrate VM is an embeddable VM for a subset of Java and optimized to execute Truffle languages ahead-of-time. In this context Graal is used to perform static code analysis over all application and VM infrastructure code. Subsequently Graal is used again to compile all reachable code and data into a single native code image. At last debuginfo is added to allow debugging of the AOT-compiled Java code with native debuggers (e.g. GDB). The final result is a native executable that allows to run truffle languages without the start-up overhead of a real Java VM. At the end of the talk a Javascript-Truffle native executable is demonstrated (run and debug) that is built with Substrate VM.
