LLDT
Loads the Local Descriptor Table register (LDTR) with the 16-bit selector specified by the source operand.
The following table specifies the supported source and destination operands.
| source | destination(s) |
|---|---|
| reg | LDTR |
| m16 | LDTR |
| imm | #I |
DO NOT support LOCK
LLDT is available in legacy mode and compatibility mode. It is NOT supported in 64-bit mode.
The selector must be a valid index into the Global Descriptor Table (GDT) and must point to a Local Descriptor Table (LDT) descriptor. If the selector is null or the descriptor is not a valid LDT descriptor, a General Protection Exception (#GP) SHALL be generated. The instruction updates the hidden portion of the LDTR with the base address and limit from the referenced descriptor.
