Building Graal -------------- There is a Python script in graal/mxtool/mx.py that simplifies working with the code base. It requires Python 2.7. While you can run this script by using an absolute path, it's more convenient to add graal/mxtool to your PATH environment variable so that the 'mx' helper script can be used. The following instructions in this file assume this setup. Building both the Java and C++ source code comprising the Graal VM can be done with the following simple command. mx build This builds the 'product' version of HotSpot with the Graal modifications. To build the debug or fastdebug versions: mx build debug mx build fastdebug Running Graal ------------- To run the VM, use 'mx vm' in place of the standard 'java' command: mx vm ... To select the fastdebug or debug versions of the VM: mx --fastdebug vm ... mx --debug vm ... Graal has an optional bootstrap step where it compiles itself before compiling any application code. This bootstrap step currently takes about 7 seconds on a fast x64 machine. It's useful to disable this bootstrap step when running small programs with the -XX:-BootstrapGraal options. For example: mx vm -XX:-BootstrapGraal ...
