--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> ---
So SPARC has

static machine_mode
sparc_preferred_simd_mode (machine_mode mode)
{
  if (TARGET_VIS)
    switch (mode)
      {
      case SImode:
        return V2SImode;
      case HImode:
        return V4HImode;
      case QImode:
        return V8QImode;

      default:;
      }

  return word_mode;
}

which means it is unconditionally vect64 (I assume word_mode is DImode).
