Intel Publishes "X86-S" Specification For 64-bit Only Architecture

Intel quietly released a new whitepaper and specification for their proposal on "X86-S" as a 64-bit only x86 architecture. If their plans workout, in the years ahead we could see a revised 64-bit only x86 architecture.

Entitled "Envisioning a Simplified Intel Architecture", Intel engineers lay the case for a 64-bit mode-only architecture. Intel is still said to be investigating the 64-bit mode-only architecture that they also refer to as "x86S". Intel is hoping to solicit industry feedback while they continue to explore a 64-bit mode only ISA.

[...] Under this proposal, those wanting to run legacy 32-bit operating systems would have to rely on virtualization. To further clarify, 32-bit x86 user-space software would continue to work on modern 64-bit operating systems with X86-S.

    Wait, aren't we seeing one now? See above. Literally the previous line was they just released an architecture plan for 64-bit only.

    No, read your own quotes again. Architectures *exist*. We're now seeing the *proposal* for the architecture - a proposal is not the thing. It's not even the plan for the thing - at best it's a draft of a plan for the thing.

    Like, if your girlfriend came in and proposed making lasagna for dinner, you wouldn't have lasagna. You wouldn't have even the recipe for the lasagna. All you would have is the proposal.
