>Windows 8 on ARM won't support legacy x86 code
On one hand I doubt this as MS has a penchant for backwards compat and there is an emulation layer for EVERYTHING in Windows as is.
On the other hand, I'm seeing them move away from their backwards compat religion and CISC to RISC sounds fucking horrifying to me.
- iuguy 16y agoI absolutely agree with you about the penchant, but I know first hand from Microsoft employees that the backwards compatibility issue is a complete pain in the arse. Supporting ARM on managed only paves the way to ditch unmanaged code in x86_64 in the future. Supporting native unmanaged code might require a recompile and some testing, but might be possible (given the Xbox 360) but then you're going to have trouble with x86_64 only references in your code. Implementing some sort of x86 -> ARM is going to be a nightmare of epic proportions, Rosetta-type technologies be damned.
