Linaro GCC has some test regressions vs. FSF GCC:
+FAIL: gfortran.dg/vect/vect-2.f90 -O scan-tree-dump-times vect "Alignment of access forced using peeling" 3
+FAIL: gfortran.dg/vect/vect-2.f90 -O scan-tree-dump-times vect "Vectorizing an unaligned access" 2
+FAIL: gfortran.dg/vect/vect-3.f90 -O scan-tree-dump-times vect "Alignment of access forced using peeling" 1
+FAIL: gfortran.dg/vect/vect-3.f90 -O scan-tree-dump-times vect "Vectorizing an unaligned access" 1
+FAIL: gfortran.dg/vect/vect-4.f90 -O scan-tree-dump-times vect "Alignment of access forced using peeling" 1
+FAIL: gfortran.dg/vect/vect-4.f90 -O scan-tree-dump-times vect "Vectorizing an unaligned access" 1
+FAIL: gfortran.dg/vect/vect-5.f90 -O scan-tree-dump-times vect "Alignment of access forced using peeling" 1
+FAIL: gfortran.dg/vect/vect-5.f90 -O scan-tree-dump-times vect "Vectorizing an unaligned access" 1
Cause unknown as yet, but it might be related to bug #602289.
