Could you explain how this differs from other meta-circular interpreters like Narcissus? Is it correct to say that this is not a tree-interpreter like Narcissus, but a JavaScript to native compiler written in JS. If it's not a tree-interpreter, then running inside a JVM that has ephemerons doesn't help you on the GC front? Does the native code generated fit within the NaCL alignment restrictions? When you say you don't have exceptions, does that mean you lack anything related to protected regions? try...finally _______________________________________________ es-discuss mailing list es-discuss@mozilla.org https://mail.mozilla.org/listinfo/es-discuss
