Really thank you very much again!! I have implemented sw_64 tcg back end, its performance is much better than tci (10 times faster for testing i386 bash). I guess at present, our qemu performance should be enough for my current using. :-) And next, I shall try to merge alpha related code to the latest qemu, and send patches for it. Hope it is useful for our qemu (since no any additional reply for it, I guess I should try to send patches for it).
