The dynarec core (dynamic recompiler) has some x86 dependencies, AFAIK.
But it's not exactly tied to the original 8086 instructions, maybe. More like i386, I assume.
Anyway, it's not going to break DOSBox. A small modification/recompile should get around this issue. That being said, I'm merely a user. 🤷♂️
Edit: Hm. Rings 1 & 2 are being removed in X86-S. 16-Bit Real-/Protected Mode and Segmentation support, too. - This may affect Wine/Wabi on modern Linux, too. Or recent OS/2 (ArcaOS), which can boot from UEFI.
Then the list goes on with 32-Bit Ring 0, V86, the old 8529 PIC, x87 FPU bits (CR0)..
Doesn't look nice. As I worried/warned for years, Intel finally began killing the roots of x86.
The forcefully removable of CSM (BIOS emulation) was the start. It needed Real-Mode the most. Then the decline of shipping VGA/VBE BIOS in recent graphics cards.
If things go on, hardware-assisted virtualization (AMD-V, Intel VT) will suffer from this, too.
Edit: On the other hand.. This is "just" a white paper.
Maybe intel is testing reactions of the IT? Some sort of provocation, to see if anybody cares?
