Struct x86_64::instructions::segmentation::SS[][src]

pub struct SS;
Expand description

Stack Segment

Entirely unused in 64-bit mode; setting the segment register does nothing. However, in ring 3, the SS register still has to point to a valid Descriptor (it cannot be zero). This means a user-mode read/write segment descriptor must be present in the GDT.

This register is also set by the syscall/sysret and sysenter/sysexit instructions (even on 64-bit transitions). This is to maintain symmetry with 32-bit transitions where setting SS actually will actually have an effect.
