资 源 简 介
The OpenJIT project is an ongoing Java™ JIT compiler project as a collaborative effort between Tokyo Institute of Technology and Fujitsu Laboratory, partly sponsored by the Information Promotion Agency of Japan. OpenJIT is a "reflective" JIT compiler in that not only it is almost entirely written in Java, but also that it bootstraps and compiles itself during execution of the user program, and compiler components coexist as first-class objects in user heap space. Thus, users can tailor and customize the compilation of classes at runtime for variety of purposes such as application-specific optimization and partial evaluation, dynamic, compiler-assisted environment adaptation of programs, debugging, language extension and experimentation, and other types of advanced compiler-based research and applications. OpenJIT even allows full dynamic update of itself by loading the compiler classes on the fly from the network.
