--- Comment #10 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
We now get (at least on aarch64):
t.f90:11:0: note: === vect_pattern_recog ===
t.f90:11:0: note: === vect_analyze_data_ref_accesses ===
t.f90:11:0: note: Detected single element interleaving *a_23(D)[_22] step 8
t.f90:11:0: note: Data access with gaps requires scalar epilogue loop
t.f90:11:0: note: not consecutive access *a_23(D)[_25] = _28;
t.f90:11:0: note: not vectorized: complicated access pattern.
t.f90:11:0: note: bad data access.
