Any equivalent look at Apple's Rosetta 2? Perhaps if author has time and availability of hardware, they can have a similar look. Rosetta 2 is going away next year, and it's a shame, even if from a purely technical reason. Apple will never open source it.
My daily driver is a M2 Mac, and we added the same set of optimisations to ARM on Mac as we did to ARM Windows (at the same time as Intel Windows we measured emulation of in this blog.) More info: https://blogs.remobjects.com/2026/01/26/fast-math-in-six-lan...
We did not try to especially optimise Intel Mac, but it's very tempting to do so in order to look at it as you ask.
I wish Rosetta was open sourced too. Same with Prism. I think any and all translation tech could only benefit everyone.
Well, Prism is likely to be with us for a decade, if not more, since Microsoft actually cares about backwards compatibility, whereas Apple much less so, and I guess, to them, we're at a "good enough" state. So Microsoft releasing it is less likely, but Apple could, especially after it is done. But I suspect some asshole sees a "competitive advantage" somewhere, and won't sign off a source release. What a gut punch for the team that worked on it.
Looking forward to a future look at Rosetta 2. Thanks!
Given enough motivation, access control is irrelevant too. See early Windows "private" API that was used for decades and Microsoft supported despite being "private", because they knew it was being used and they (used to) care about their users.
