--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed.

in fold_offsetof, we still have:
```
    case COMPONENT_REF:
...
      off = size_binop_loc (input_location, PLUS_EXPR, DECL_FIELD_OFFSET (t),
                            size_int (tree_to_uhwi (DECL_FIELD_BIT_OFFSET (t))
                                      / BITS_PER_UNIT));

```

and:
```
    case ARRAY_REF:
...
      off = size_binop (MULT_EXPR, TYPE_SIZE_UNIT (TREE_TYPE (expr)), t);
```
