If you had read the next sentence you'd have found out that I did read some papers about that (where I learned about trace trees). My guess was just about whether their Java compiler used trace trees or the other possibility, i.e., trace stitching (as I now learned). But thanks for the references, I'll have a look later. -- Paolo Giarrusso - Ph.D. Student http://www.informatik.uni-marburg.de/~pgiarrusso/ _______________________________________________ [email protected] http://codespeak.net/mailman/listinfo/pypy-dev
