its such a fascinating thing that most people just ignore
i too wrote (using AI) an article on Branch Prediction after i found out that most of my team members only read this in college but never understood
Nice article! Always good to see easy-to-follow explainers on these kinds of concepts!
One minor nit, for the “odd corner case that likely never exists in real code” of taken branches to the next instruction, I can think of at least one example where this is often used: far jumps to the next instruction with a different segment on x86[_64] that are used to reload CS (e.g. on a mode switch).
Aware that’s a very specific case, but it’s one that very much does exist in real code.
