Consider the following C function:
 
<c>
int gcd(int a, int b) {
  static int temp = 0;
  if (temp) temp = swap(&a, &b);
  while (1) {
    a %= b;
    if (a == 0) break;
    b %= a;
    if (b == 0) return a;
  }
  return b;
}
</c>
 
== Postfix Code ==
 
The Postfix code for the above function is as follows:
 
<asm>
 
</asm>
 
== Compiling and Running ==
 
To compile the Postfix code directly, [[pf2asm]] can be used:
 
* pf2asm gcd.pf
* yasm -felf gcd.asm
