           Summary: tail call missed with struct wrapper
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Keywords: missed-optimization
          Severity: enhancement
          Priority: P3

          Reporter: pinskia at gcc dot gnu.org

Take:
int *g();
f h()
{
    return {g()};
}

f should tail call to g but currently does not.
