--- Comment #6 from Marc Glisse <glisse at gcc dot gnu.org> 2012-09-18 16:06:43 UTC --- (In reply to comment #2) > The bug is obvious, vect_gen_perm_mask is not suitable for uses outside of the > vectorizer, it uses e.g. current_vector_size. Argh, I was happy to find a function that did just what I needed, and I couldn't see any reason why it would need anything besides what was passed as arguments, so I went ahead without looking too closely, sorry. Thanks a lot Jakub for handling it so quickly (I am away for the first half of this week). By the way, I still don't understand why vect_gen_perm_mask uses current_vector_size when it has nunits at its disposal. Would it be useless to change that (assuming it makes sense)?
