--- Comment #12 from Jacob Lifshay <programmerjake at gmail.com> ---
Note that I proposed a different C/C++ attribute than vector_size since it
needs to support subvectors and because I'm not sure how much work it is to
relax the current gcc requirement that vectors must be power-of-2 sizes. If
that's a front-end only requirement, than we could probably just reuse the
vector_size attribute. If that's required in the GCC IR, then we should
probably create our own attribute since that'll be less work.

Alex, I (and probably Luke too) don't need the automatic loop vectorizer to
work for the initial implementation, so that can be left for later if desired.
