--- Comment #7 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I have a patch which implements V4QI for many operations (extends and
widden_<su>sum) (though I need to fix the cost model).
I am able to get:
```
sshll v30.4h, v30.8b, #0
smull v31.4s, v31.4h, v30.4h
addv s31, v31.4s
```
But the load is still using inserts and tbl. I have not figured out why though.
