--- Comment #13 from Robin Dapp <rdapp at gcc dot gnu.org> --- And another FYI. My take is, if we need to touch everything anyway, then let's rather improve things entirely instead of treating symptoms. The hope is that with a proper and generic RTL vector predicate most of the patterns in autovec-opt.md could just vanish and we'd emit predicated instructions during expand right away.
