The OpenJIT project is an ongoing Java the programming language 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.
|
|
|
|
OpenJIT is fully JDK compliant, and plugs into standard JVMs several Unix
|
|
platforms such as Solaris (Sparc), Linux (x86), and FreeBSD (x86).
|
|
|
|
On Linux/x86 platform, OpenJIT 1.1.14 is faster than the JDK 1.2 classic VM
|
|
compiler, runs more or less the same speed as other commercial JIT compilers on
|
|
classic VM.
|
|
|
|
OpenJIT is completely free so long as it is used for non-commercial purposes.
|
|
Its source, binaries, etc. can be freely distributed and modified without
|
|
restriction.
