Well, conversion to fixed-point is much more complex than that. It
involves looking at the range and percision needed for every part of the
code. There's no generic library that can do that. Once this is done you
could eventually use the Intel libs to optimize a bit more, but even
then I doubt there's much to gain from doing that.
