--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
here is another testcase which shows the issue with pulling the constant one
out of the loop when it could have been merged with the csel to use csinc:
```
int f(int *a, int n, int *b, int d)
{
  for(int i =3D 0; i < n; i++)
    b[i] =3D a[i] =3D=3D 100 ? 1 : d;
  return 0;
}
```=
