--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I am suspecting r16-4212-gf256a13f8aed83 .

The generic from the C front-end seems less like optimal too:

  c = TARGET_EXPR <D.4597, (void) (D.4597 =
VIEW_CONVERT_EXPR<int>(__atomic_load_4 ((const volatile void *) &saved, 5)))>;

I can't remember how TARGET_EXPR work but I thought there was a way of being
able to remove them if it was trival to do so.
