I’ve started noticing articles and YouTube videos touting the benefits of branchless programming, making it sound like this is a hot new technique (or maybe a hot old technique) that everyone should be using. But it seems like it’s only really applicable to data processing applications (as opposed to general programming) and there are very few times in my career where I’ve needed to use, much less optimize, data processing code. And when I do, I use someone else’s library.

How often does branchless programming actually matter in the day to day life of an average developer?

    It matters if you develop compilers 🤷,

    Otherwise? Readability trumps the minute performance gain almost every time (and that’s assuming your compiler won’t automatically do branchless substitutions for performance reasons anyway which it probably will)
