Function rustc_ty_utils::needs_drop::filter_array_elements

fn filter_array_elements<'tcx>(
    tcx: TyCtxt<'tcx>,
    param_env: ParamEnv<'tcx>
) -> impl Fn(&Result<Ty<'tcx>, AlwaysRequiresDrop>) -> bool

HACK: in order to not mistakenly assume that [PhantomData<T>; N] requires drop glue we check the element type for drop glue. The correct fix would be looking at the entirety of the code around needs_drop_components and this file and come up with logic that is easier to follow while not repeating any checks that may thus diverge.
