Hi, With the recent discussions of JIT/AOT and the good progress we made on PHP-7, we decided to open up the JIT experiment we've been working on.

https://github.com/zendtech/php-src/tree/zend-jit/ext/opcache/jit You may just clone or pull zend-jit branch and compile/configure according to instruction. Don't merge it with master. It may work today but will stop working tomrrow. Disclaimers: - It's an experiment, and is not in any way ready for anything. In the future we may try to implement JIT quite different from this PoC. - I'm not planning to invest into it in the near future. (PHP-7 takes all my time) Consider it available for academic purposes only at this point. Enjoy! Thanks. Dmitry.
