I find strange your point about ARM vs MIPS given that ARMv8 seems much more 'MIPSy' than previous ARM ISAs..

  Why? It's very intentionally not MIPSy. ARMv8 removes anything that may dictate any microarchitecture decisions, while MIPS exposes it in an ISA (delay slots and all that). Even predication had been killed for this reason (it's not good for OoO anyway).

    Yeah, but * mips didnt have predication to begin with * arm didnt have delay slots to begin with * and then afaik 64b arm uses more registers and removes shifter operands So definitely more mipsy.

      If "simpler" = mipsy then yes. If "mipsy" = "closer to hardware" then definitely not.

        MIPSy = closer to MIPS, the actual ISA.
