Dari C:

#include <stdio.h>

int main() {
  int x = 10;
  int y = 100;
  printf("x + y = %d", x + y);
  return 0;
}

menjadi assembly x86_64:

section .data
    msg db      "hello, world!"

section .text
    global _start
_start:
    mov     rax, 1
    mov     rdi, 1
    mov     rsi, msg
    mov     rdx, 13
    syscall
    
    mov    rax, 60
    mov    rdi, 0
    syscall
