There doesn't seem to be any context on whether this was an intentional feature, intended to be used by userspace programs, or something entirely undocumented that wasn't intended to see widespread use. What's more, it doesn't dive into why it matters - if the microarchitecture's the same, isn't the only benefit a shorter pipeline; maybe you can skip some of the complex CISC->RISC decoding? Itanium seems to have, in any case, shown us that exposing the microarchitecture for the sake of performance is an antipattern. |
