Re: Problem with "mov" in GNU GAS

Hello everybody,

I am writing a simple ASM code with GNU GAS. I am having some problems
with mov command. Please could anybody tell me why 2 lines (*) and
(**) are not equivalent?? (currently my code works as expected with
(**), but not with (*)

(My program is in 16bit mode)

---
var:
.long 0xf1234

So var is an address. At that address is reserved space for a
long, which is to be initialised to 0xf1234.

.code16gcc
movl var, %ecx // (*)

Here ecx now holds the address where the 0xf1234 above is stored.

movl $0xf1234, %ecx // (**)

But here ecx is set to the constant value 0xf1234.
