Windows So, a rudimentary jailbreak for Windows RT made its way onto the web these past few days. Open source applications were ported right away, and it was confirmed that Windows RT is the full Windows - it's exactly the same as regular Windows, except that it runs on ARM. Microsoft responded to the jailbreak as well.

Member since:

So we can finally agree that the direct translation approach has inefficiencies that cannot be avoided without optimising the code for ARM.

As I wrote, I'd prefer just to re-schedule translated code to fit issue slots. I didn't understand why you're mentioned flag registers overhead. So you probably thought about x86 flag register update after every operation? Sorry I didn't stated that explicitly, but translation engine should trace flags usage for basic blocks. This is a baseline requirement.

You say efficiency isn't important to you if but if an optimiser could significantly increase active runtime

I'm not sure that you'll achieve a _much better_ results with complex optimizations.
