--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Reduced testcase:
```
float counter(int maxl) {
float tenth=0.1f;
float sum = tenth;
int n=0;
while(n<maxl) {
sum += tenth;
++n;
}
return sum;
}
```
As I mentioned this is vectorized starting in GCC 7 which gives a decent speed
up but it could be optimized to just `sum = max1 * tenth + tenth` really.
