Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Component|regression |testsuite Target Milestone|--- |4.9.2 --- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> --- Try -fno-common - the store is also misaligned otherwise as 'out' is a common. We've fixed 4.9 to no longer align commons (because we can't do that reliably). IIRC the vectorizer testsuite was "fixed" to pass -fno-common everywhere but apperantly some tests were missed?
