The PDF goes into detail on this. tl;dr:
> 16-bit and 32-bit protected mode are not supported anymore and cannot be entered. The CPU always operates in long mode. The 32-bit submode of Intel64 (compatibility mode) still exists.
- dathinab 3y agoYes but there is a bit of a catcher due to some 32bit programs abusing certain instructions created for handling segmentation. And segmentation support will be partially removed. But no idea if the instruction in question will be gone.
- anticensor 3y agoRemoved instructions and pseudocode of changing instructions are explicitly documented.
