The Original Code
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
