            Bug ID: 110745
           Summary: Improve printing of base classes
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mpolacek at gcc dot gnu.org
  Target Milestone: ---

Prompted by <https://gcc.gnu.org/pipermail/gcc-patches/2023-July/624964.html>:

struct B { int i; };
struct D : B {
    int x;
    int y;
};

int
main ()
{
  D d = {.x=1, .y=2};
  (void)d;
}

$ ./cc1plus -quiet q.C -Wmissing-field-initializers
q.C: In function ‘int main()’:
q.C:10:20: warning: missing initializer for member 'D::<anonymous>'
[-Wmissing-field-initializers]
   10 |   D d = {.x=1, .y=2};
      |                    ^

We should be able to say 'D::B' instead.
