Can you provide documentation on the various functions? I was trying to extend this for PPC and I had a hard time trying to figure out what I needed to do enable to get this working. I was able to see it did something for loops but it wasn't able to identify any shrink wrap opportunities for this simple tc:
int doSomething(int a, int b);
int test (int a, int b) {
int c=a;
if (a < b) {
c = doSomething(0, a);
}
return c;
}
