I don't get any noticeable performance change when I unroll the loop by 2 by hand. I suspect that on a modern CPU loop unrolling probably isn't that much of a win. I'm more interested in strength reduction, especially when computing things like indices into multidimensional arrays. Anyone know how well ghc performs in this area? -- Dan _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
