As before, I'm still confused here. This still returns false, i.e. bails out of

that? Or do we just not care because it won't be vectorizable anyway???
This seems like an opportunity for more optimization in the future....

Where can I find info on what the different flag values mean?

Sorry; I don`t know if that is documented anywhere yet.
In this case, (-1) simply means "defaulted": on if the vectorizer is on, and
off if it is off.
(0) means "user specified no if conversion" and (1) means "user specified [yes] if
conversion".
Ah, right, that makes sense now. Obviously I would like to see this written in
doc/ .
Cheers, Alan
