One of the things making x86 hard to implement is the flags register. Flags are set as a side effect of many instructions. I'd be really interested to see how Intel or AMD handle the flags in a modern processor. RISC-V gets rid of ISA defined flags entirely, so that problem goes away. In some cases the lack of flags can lead to slower software, but 99.9 percent won't miss them.
