            Bug ID: 64172
           Summary: [4.9 Regression] Wrong code with GCC vector extensions
                    on ARM when compiled without NEON
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: siarhei.siamashka at gmail dot com

The attached partially reduced testcase misbehaves at runtime if it is compiled
using GCC 4.9.2 on ARM with -O2 optimizations and without -mfpu=neon. Reducing
optimizations to -O1 helps.
