Yes, I've certainly done that kind of thing, especially with code for
smaller chips (where I usually code in assembly). It can really make a
difference. But in this case, I did nothing to write 'optimal' C, just a
straightforward implementation of the algorithm. I was very impressed with
the compiler.
