Brendan Eich: "One point about Trace Trees (as opposed to less structured kinds of tracing): you get function inlining without having to build interpreter frames at all, because the trace recording must reach the loop header in the outer function in order to complete. Therefore, so long as the JITted code stays 'on trace', no interpreter frames need to be built."
Fast JIT for JavaScript - wow. Let's have some Devo:
