Something interesting:
In atomic_kind_types.F.085t.copyprop3, we have:
:
D.2711_888 = *atomic_kind_38(D);
D.2731_889 = &D.2711_888->element_symbol[1]{lb: 1 sz: 1};
__builtin_memcpy (&element_symbol[1]{lb: 1 sz: 1},

-fdump-tree-fab-details:
;; Function read_atomic_kind (__atomic_kind_types_MOD_read_atomic_kind)
Simplified
__builtin_memset (&element_symbol[2]{lb: 1 sz: 1}, 32, 1);
to
(void) 0;
