Hi Hideki,
I think you're comments are spot on:
> It all depends on to whom we are providing these pragmas.
Pragma's are user-facing "options" to override or force compiler decision making. I don't think there's another way to look at it, but please correct me if I'm wrong.
That's exactly the reason why I think `vectorize(disable)` should disable vectorisation for that loop. I just don't see what else a user would expect.
