--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.
Note if the final convert was a truncation from the original one, match is able
to remove the inner cast since r14-2890-gcc2003cd87532f (PR 93044).
That is:
```
unsigned char
foo1 (signed short x)
{
unsigned long long y = x;
return y;
}
```
Maybe that part of the pattern could be improved to catch the testcase in
comment #0 too.
