--- Comment #10 from Marc Glisse <glisse at gcc dot gnu.org> --- Two random links into the latest conversation: https://gcc.gnu.org/ml/gcc-patches/2014-07/msg01812.html https://gcc.gnu.org/ml/gcc-patches/2014-06/msg02288.html That version of the patch doesn't handle integer vectors IIRC, but it is the principle that matters, if the first step is accepted I'll extend it. I suppose I should ping it again soon...
