ind variable
This support was removed years ago from indvars. We don't need canonical
induction variables any more as all analysis are done on SCEVs. The SCEV
generator can transform them even without the need for explicit
canonical induction variables.

ind variable
Hello,
I have this piece of code:
int main() {
int m = 0;
// int i, j, k;
// int N = f()%10;
for (int l = 0; l < 1000; l+=4)
printf("%d", l);
I am sure, that llvm is capable to convert this into canonical induction
variable, but even with O3
define i32 @main() #0 {
br label %2
; <label>:1 ; preds
