--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
It can use alignment of the whole structure whose part is accessed, as long as
it is actually accessed.
We can't derive alignment from mere existance of pointer (at least in GIMPLE),
that would break too much real world code, but whenever anything from the
structure is accessed, we can rely on the full alignment of it.
