Re: Int vs Word performance?

PS. perhaps on newer 64 bit machines, explicitly selecting 32 bits can offer savings? I'd certainly expect selecting 64 bits on a 32 bit machine to lead to slowdowns.

Unlikely, I'd have thought. We implement all the explicitly sized integral types by zero-extending or sign-extending to the size of an Int/Word. That's why there are no primitive types or operations for Word8#, Word16#, etc. Cheers, Simon
