--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Can you modify:
```
/* x & 0 -> 0  */
(simplify
 (bit_and @0 integer_zerop@1)
 @1)
```
to
```
/* x & 0 -> 0  */
(simplify
 (bit_and:c @0 integer_zerop@1)
 @1)
```

That in theory should not matter but I don't think we simplify normally VLA
constants ...
