We already saw the "W^X" issue. A possible solution would be indeed for the JIT to map W when it compiles and then X "when it's done", except that it is never done, as there are various places that can be patched at various point (including jump targets, and now also some young GC pointers that are replaced with their old equivalent during the next minor collection). It's not completely easy to do. It's not impossible, though. Patches welcome. A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
