Ah, didn't know about that. I don't have that flag on my main dev machine
(still using 3.4 branch) but I do have it on my laptop.
Also, currently the vectorizer is applied only on loops. (please see the
Auto-vectorization
page for examples)
Ah, didn't know about that either. Is it likely to work on non-looped code in
the future? Not that it matters that much as this code is generated and easy
to change.
thanks,
