Branchless computing (https://www.youtube.com/watch?v=g-WPhYREFjk) is a technique which may help a lot with mitigating the overhead of branching. Alternative way, coming from linux kernel (https://docs.kernel.org/staging/static-keys.html) is to leverage knowledge about branches direction and literally change the instructions via run-time code patching to…</p><p><a href="https://hackerpaper.kaipfister.de/p/2308.14185/">Paper and discussion history</a>.
