it's a relative pos to the start of the block and it's used for relative jumps. if you want to do absolute jumps, you need to patch them later using the value that's returned from materialize() (that writes it to memory). At least x86 backend has some jump patching done Cheers, fijal _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
