--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Yes it does bisect to that but it was a latent missed optimization.
In that this does not vectorize either:
```
unsigned int a[19];
void f2(bool b[19]) {
for (int i = 0; i < 19; i += 1)
{
unsigned t = b[i];
a[i] = -t;
}
}
```
When it should.
