I know my idt and idt_pointer are valid, because they work. but they're defined in asm.

Rust code:

extern {
    static idt: u64;
    static idt_pointer: IdtPointer;
}

#[derive(Debug)]
#[repr(packed,C)]
pub struct IdtPointer {
    limit: u16,
    base: u64,
}

assembly:

global idt
global idt_pointer

idt:
    %assign i 0
    %rep 256
        IDT_ENTRY i
    %assign i i+1
    %endrep

idt_pointer:
    dw 4095   ; limit
    dq idt


This then prints false.

    kprintln!("IDT INFO");
    kprintln!("--------");
    kprintln!("idt: {:?}", idt);
    kprintln!("idt_pointer: {:#?}", idt_pointer);
    kprintln!("equal: {}", idt_pointer.base == idt);

why?
