Once the Packager has created the CompiledCode, Rubinius will write the method to a file for future consumption. For instance, after a file is required for the first time, subsequent requires will load the file from disk, rather than loading in the Ruby code, then parsing and compiling it.
This stage is extremely simple. It takes the original input file name,
c to the end, and calls Rubinius::CompiledFile.dump with the
CompiledCode from the previous stage and the file name to write to.
Once it finishes writing the file to the disk, it returns the input (the CompiledCode), which becomes the return value of the entire compiler process.
CompiledFile.dumpis called in order to perform the actual dumping.
This stage is actually optional, and is only used when compiling a file. When compiling a String, such as with eval, this step is skipped. In that case, the compiler stops in the Packager stage, and returns the CompiledCode from that stage as the return value of the compiler.
Because of the architecture of the Rubinius compiler, it is easy to add additional stages to the end of the process, and as long as each of those stages returns the inputted CompiledCode (or a different CompiledCode), everything will work as expected.
