I've been writing a bunch of branch-free code recently, so I took a crack at it. In my world, data-dependent table lookups might as well be branches, so let's eliminate those as well. Here's a fizzbuzz(char*, int) function that can accept any number up to 99999999, and will put the correct FizzBuzz result into the provided buffer (either the printed number, "Fizz ", " Buzz", or "FizzBuzz"). As promised, it's loop-free, and as a bonus it should be constant-time as well: Assembly: http://pastebin.com/EnJEuxnp http://pastebin.com/EnJEuxnp compiled from this C: http://pastebin.com/PCQQQ2cn http://pastebin.com/PCQQQ2cn [edit] generated from this Python: http://pastebin.com/ijr3thE2 http://pastebin.com/ijr3thE2 Pastebinned since it's about 700 assembly instructions. Unrolling the loop and printing to the screen are left as exercises...
