[PATCH] Fix PR60012

2014-02-03 Thread Richard Biener
This fixes PR60012 by considering TBAA for all DDRs in vectorizer dependence analysis because the vectorizer can rely on at least covering two scalar iterations. It _should_ be a regression from 4.4 but I can't make a testcase that has two TBAA disambiguatable types and is vectorized with 4.4 it
