Why does Intel keep having and adding so so so very many instructions that are undocumented in every form… It’s so horrible from a security standpoint (hence why so many theories that a lot of these are for exploitations) and it just complicates the chips even further. We need everything to switch to RISC-V or something, and keep it to the spec… >.>
