> IMO it's not possible in theory to build a branch predictor that never makes potentially exploitable mispredictions. I believe the Mill hardware design would be immune by design because the hardware is in-order (relying on other trickery for its performance). Of course, it's still vaporware, but the noises made have been fairly competent. So in some ways, yes, but in other ways, what if you didn't need a branch predictor in the CPU. https://millcomputing.com/blog/wp-content/uploads/2018/01/Spectre.03.pdf https://millcomputing.com/blog/wp-content/uploads/2018/01/Sp... https://www.youtube.com/watch?v=8E4qs2irmpc https://www.youtube.com/watch?v=8E4qs2irmpc
