--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think there was some inconsistencies in C vs. C++ FEs in this area (but as
usual I don't remember exactly but I remember Uli complaining about it again at
the Caulrdon).

I believe it was sort-of automatic integer promotion rules should apply if
they don't change vector sizes (thus, the sign promotion parts should apply).

That's not "ignoring" signs but doing the appropriate (view-)conversions.
