> Is there anything comparable surviving today? I'm not aware of such Super CISC instruction sets in popular use today, but I wonder with VM's and statistically-based AI proliferating now, whether we might revisit such architectures in the future. Could continuous VM-collected statistical data inform compiler and JIT compiler design to collapse expensive, common complex operations we can't identify patterns for with current methods into Super CISC instructions that substantially speed up patterns we didn't know previously existed, or are our current methods to analyze and implement compilers and JIT's good enough and what's mostly holding them back these days are other factors like memory and cache access speed and pipeline stalls?
