| Has anyone looked at this very small JVM implementation for some ideas? http://www.rtjcom.com/ If we want to have Python run on low-memory systems then this will help. There are other small JVMs which are genuinely open source (unlike [http://www.rtjcom.com/ simpleRTJ]), and a list of such projects can be found [http://www.kaffe.org/links.shtml via the Kaffe project site]. -- PaulBoddie |
Some of the backends supported in 1.0 (namely The LLVM and the JS backends) have been dropped "because they were unmaintained and/or buggy". The old JIT has also been dropped in favor of a new one that is under active development. |
