Frankly I am not sure whether gcc will optimize away those multiplications and summations. I will appreciate it if you will find out and let me know.
I tried with gcc -O3. It seems gcc does the optimization I described above, but it still end up with more conditional jumps and an extra imul and a few incl than an straight forward if version.
It does a pretty good job, but we are asking too much :)
