Maybe you missed the point I made in the paragraph you quote? Without a JIT, "a <op> b <op> c" cannot reasonably be done in a single iteration over the three arrays. The pull request you quote improves the memory and cache pressure by doing some assignments in-place, but "a + b + c" still works in two passes: in pass one it writes intermediate data that will be re-read in pass two. A bientôt, Armin. _______________________________________________ pypy-dev mailing list pypy-dev@python.org https://mail.python.org/mailman/listinfo/pypy-dev
