A big problem with the Mersenne Twister is the shifts. As has been noted elsewhere, ghc doesn't do such a great job on those.
Actually, the shifts are only evaluated once (hurrah for lazy evaluation) and with -funfolding-use-threshold=16 they're all compiled to unchecked primitives (GHC.Prim.uncheckedShiftRL#). -- Cheers, Lemmih _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
