Thanks for replying, much appreciated. I admit that my interest primarily goes towards desktop application and my comment was made from that angle. Regarding conditional instructions on in-order microarchitecture: I neither have a strong opinion nor am I familiar with the discussion. Intuitively at least, conditional instructions do seem like a useful tool for simple in-order CPUs, but as you point out instruction fusion can be used to solve a lot of things. It’s a question of tradeoffs, and it is not obvious to me what cost these tradeoffs bring. It does seem that RISC-V will need to more heavily rely on operation fusion to achieve better performance and efficiency (as opposed to something like ARM where some patters are already “pre-fused” in the ISA). The time will tell. I don’t think that any of these are trivial.
