Is glorious the right word for it? We’re going back to the stone ages where processors couldn’t predict the targets of indirect jumps. More generally, this seems to me like an attempt to patch out of what is really a class of attacks leveraging fundamental assumptions about high-performance CPU design. Before, OOO just had to preserve correctness and (some of) the order of exceptions and memory operations. Now, it has to preserve (some of) the timing of in-order execution too? Where does this path end?
