--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
The split for avx_cmpv4sf3_1 has not changed since r11-6849-gee78c20e74d302 . I
don't know why it is only showing up now.
This will work around it.

})
```
But I am not 100% sure it is the correct fix.
Note only test2 is needed here to get the ICE.
