--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The combine issue is:
```
Failed to match this instruction:
(set (reg:DI 101 [ _3 ])
(and:DI (not:DI (reg:DI 104))
(const_int -9187201950435737472 [0x8080808080808080])))
Successfully matched this instruction:
(set (reg:DI 102 [ _1 ])
(not:DI (reg:DI 104)))
Failed to match this instruction:

```
which is very similar to PR 111949 and similar to PR 115086.
