This is my code so far for a multiply function that cannot use any multipaction and division operators.

.intel_syntax noprefix

.globl _x
_x: .long 0

.global _y


.globl _fac
push ebp
mov ebp,esp

mov eax,0
mov edx,1
mov ebx,_x

mov ecx,_y

cmp edx,ecx
xchg ecx,ebx


cmp edx,ecx
add eax,ebx
SUB ecx,1

jmp LOOP


pop ebp #you need this too
ret #return

It works with a main.c file that calls multiply and calls the global variables x and y
