--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
The calls for clearing the padding are there before eiline:
```
std::__atomic_impl::__clear_padding<main()::HasPadding> (__exp_28);
_4 = (int) __is_weak_30(D);
_5 = std::__atomic_impl::__clear_padding<main()::HasPadding> (__i_31(D));
_6 = VIEW_CONVERT_EXPR<unsigned int>(*_5);
_7 = std::__addressof<main()::HasPadding> (__val_33(D));
retval.11_37 = __atomic_compare_exchange_4 (_7, __exp_28, _6, _4, __s_35(D),
__f_16(D));
```
Oh we are not clearing the padding of the reference ...
Is this even well defined?
