Sorry to be a pedant, but this is not correct. The optimisation is only possible when the arguments are unsigned integers which I don't think is specifiable when working in OCAML # Int64.shift_right (-2L) 1;; - : int64 = -1L (So far, so good) # Int64.div (-1L) 2L;; - : int64 = 0L (Good) # Int64.shift_right (-1L) 1;; - : int64 = -1L (Duh) _______________________________________________ Caml-list mailing list.
