The Original Code
Consider the following C function:
<c> int *traverse(int vec[], int lim) {
int *ptr = vec + lim - 1, ix = lim - 2;
while (ix >= 0) {
ptr = (vec[ix] > *ptr) ? vec + ix : ptr;
ix--;
}
return ptr;
} </c>
Postfix Code
The Postfix code for the above function is as follows:

| {{{2}}} |
Compiling and Running
To compile the Postfix code directly, pf2asm can be used:
pf2asm traverse.pf yasm -felf traverse.asm
