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 +``` + +There are a number of VM configurations supported by mx which can +be explicitly specified using the --vm option. However, you'll typically +want one of these VM configurations: + +1. The 'server' configuration is a standard HotSpot VM that includes the + runtime support for Graal but uses the existing compilers for normal + compilation (e.g., when the interpreter threshold is hit for a method). + Compilation with Graal is only done by explicit requests to the + Graal API. This is how Truffle uses Graal. + +2. The 'graal' configuration is a VM where all compilation is performed + by Graal and no other compilers are built into the VM binary. This + VM will bootstrap Graal itself at startup unless the -XX:-BootstrapGraal + VM option is given. + +Unless you use the --vm option with the build command, you will be presented +with a dialogue to choose one of the above VM configurations for the build +as well as have the option to make it your default for subsequent commands +that need a VM specified. + +To build the debug or fastdebug builds: + +``` +% mx --vmbuild debug build +% mx --vmbuild fastdebug build +``` + +## Running Graal + +To run the VM, use 'mx vm' in place of the standard 'java' command: + +``` +% mx vm ... +``` + +To select the fastdebug or debug builds of the VM: + +``` +% mx --vmbuild fastdebug vm ... +% mx --vmbuild debug vm ... +``` + +## Other VM Configurations + +In addition to the VM configurations described above, there are +VM configurations that omit all VM support for Graal: + +``` +% mx --vm server-nograal build +% mx --vm server-nograal vm -version +java version "1.7.0_25" +Java(TM) SE Runtime Environment (build 1.7.0_25-b15) +OpenJDK 64-Bit Server VM (build 25.0-b43-internal, mixed mode) +``` + +``` +% mx --vm client-nograal build +% mx --vm client-nograal vm -version +java version "1.7.0_25" +Java(TM) SE Runtime Environment (build 1.7.0_25-b15) +OpenJDK 64-Bit Cleint VM (build 25.0-b43-internal, mixed mode) +``` + +These configurations aim to match as closely as possible the +VM(s) included in the OpenJDK binaries one can download. + No newline at end of file +
