            Bug ID: 117299
           Summary: tbaa.c dg-final scan needs checking
           Product: gcc
           Version: 15.0
            Status: UNCONFIRMED
          Keywords: testsuite-fail
          Severity: normal
          Priority: P3
         Component: translation
          Assignee: unassigned at gcc dot gnu.org
          Reporter: sjames at gcc dot gnu.org
  Target Milestone: ---

I fixed up tbaa-1.c (renamed to tbaa_0.c then tbaa.c) as it wasn't being run
because of a bad filename, but its dg-final scan doesn't work on trunk:
```
/* { dg-final { scan-tree-dump-times "n_useless_values" 2 "evrp" { xfail *-*-*
} } } */
```

I've tried to figure out why but AFAICT it shouldn't have ever worked.
