Yes, I was a little bit unclear, I wanted to say: the generated code does not use the 64 bit instructions (i.e. 1 instruction for .&., for example). Of course, it works, but I suppose, much slower then it could (3-4 times, for that part?)

Have you checked this by looking at the generated assembly? I generated some assembly from GHC on windows. Here is what it looks ilke: http://hpaste.org/47610 My assembly-fu is not strong enough to tell if it's using 64bit instructions. Jason
