The page you're looking at documents the project to *add* autovectorization to GCC. That project was completed many years ago, and the feature has been present in GCC for years. I'm not disputing that there could be better documentation, but that page is not the place to find it. That page should probably get a notice added saying that the project is complete and that the page is now only of historical interest.
