--- Comment #5 from Stefan Schulze Frielinghaus <stefansf at gcc dot gnu.org> --- Thanks for clarification. I'm way to unfamiliar with the vectorizer. At some point, when I was skimming over the code, I got the impression that also other modes than those defined by the backend may appear in intermediate expressions. Anyhow, bootstrap and regtest are running.
