--- Comment #17 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed on the trunk, this is no longer a target issue:

__builtin_ia32_shufps is lowered into a VEC_PERM_EXPR now:
  _1 = MEM[(const float &)v_7(D) + 12];
  MEM[(float &)&D.5891] = _1;
  _24 = D.5891._rep.vecf;
  _25 = VEC_PERM_EXPR <_24, _24, { 0, 0, 0, 0 }>;
