Uhm .. swirl .. I guess I see what you mean .. maybe .. I see that you're
betting on the hard work on the GCC part being done for free, but your way may
still be overly complicated, and may prove not too efficient in practice.

Even GCC is probably not the most advanced thing ever .. are you aware of IBM's
DAISY ? That might be a more promising inspiration for improving VP. It's
somewhere on their site (ibm.com), a search should soon find it. Also HP have
done some work on processors emulating themselves, and incrementally improving
their code during that .. might be worth right the next look.
