As I wrote earlier, using FFI is also a candidate for getting access to
additional GMP functions. However, presently, I am not aware of a method of
doing this that does not involve some potentially significant additional
overhead. After all, Haskell Integers are not directly supported in C, so
some sort of marshalling and/or intricate access to internal GHC Haskell
structures would seem to be required.
But, as you have perhaps seen (my reply to Simon Marlow a few minutes ago on
the same matter), adding primitive operations turned out to be easy (at least
if you know exactly what you are doing). In addition, I have found that this
method with very little effort allows me to continue to write code that can
be used both via Hugs and GHC without change.
Thanks and regards
