Not that I have any authority here, but I like the new wording better. And
BTW, in the last exchange you pointed to a set of slides by B. Dinechin
about the ivdep directive; it was in fact a conversation with him that
prompted me to ask you about the semantics of your patch. I discussed
the issue with him again today and he agreed that mapping that to
safelen makes sense.
