I prefer the x86 MOV instruction: https://web.archive.org/web/20210214020524/https://stedolan.net/research/mov.pdf https://web.archive.org/web/20210214020524/https://stedolan.... Removing all but the mov instruction from future iterations of the x86 architecture would have many advantages: the instruction format would be greatly simplified, the expensive decode unit would become much cheaper, and silicon currently used for complex functional units could be repurposed as even more cache. As long as someone else implements the compiler.
