Sure, and you have to do sign handling. The advantage is that you could use a convenient encoding for length and sign, or deal with carry/borrow in a flexible manner (i.e., stealing another word from the allocation buffer). It's not exactly trivial, but the effort may be worth it. > And be extra careful, because the GMP code is GPL, so our > replacement for the mpz bits would probably end up being GPL too. Actually, it's LGPL, and interesting bits are part of libc under an even more permissive license. _______________________________________________ ghc-devs mailing list [email protected] http://www.haskell.org/mailman/listinfo/ghc-devs
