--- Comment #2 from Marc Glisse <glisse at gcc dot gnu.org> ---
I didn't notice an extra copy. What I did notice is that in one case we don't
inline, and ldist turns the copying loop into memcpy, while in the other case
we do inline, and ldist (and vectorization) fail to handle a read from a
constant string as a memory read (they don't create a DR for it).
