--- Comment #31 from Richard Biener <rguenth at gcc dot gnu.org> ---
I can't see any difference in the vectorizer dumps, one notable thing is that
we
(again) do peeling for alignment which is hardly useful on x86_64 these days,
at least if you only have a single store stream.
The code after the vectorizer looks 1:1 the same, so do the alias checks.
IVOPTs does different decisions for the outer loop (LU.c:87) that is because
with LTO we have more context (inlined the function) and thus "expansion"
brings up bigger expressions (well, that's my guess).
