I think that the big challenge is not to write fast & obfuscated code, but rather write fast and clean code. This example is small enough to test whether this is possible in C if you take the "fast" aspect to the extreme. I see the obfuscated version as practically assembly magic, even if it is written with C statements: the question is whether there is a C++ standard-conformant solution with the same or better runtime performance.

Just my stance: While "setne" solution is even better and it is my fault that I missed that possibility, I believe that for time critical routine _implementation_ it is OK to be fast at the cost of being obfuscated. And this routine can be quite limiting in tasks like webservers that generate gifs...

When optimizing, assembler magic is what you often have to use... (actually, I even plan to write some nImage routines in assembler Wink
