--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
This is a bug in backprop rather than a target issue.

We start with:
  _7 = VIEW_CONVERT_EXPR<vector(4) intD.6>(XMM0_2(D));
  _8 = ABSU_EXPR <_7>;
  _5 = VIEW_CONVERT_EXPR<vector(4) unsigned intD.9>(XMM0_2(D));
  _6 = _5 * _8;
  _3 = _6 * _6;
  _4 = VIEW_CONVERT_EXPR<__m128iD.5706>(_3);


And backprop changes it into:
  _7 = VIEW_CONVERT_EXPR<vector(4) intD.6>(XMM0_2(D));
  _8 = ABSU_EXPR <_7>;
  _5 = VIEW_CONVERT_EXPR<vector(4) unsigned intD.9>(XMM0_2(D));
  _6 = _5 * _7;
  _3 = _6 * _6;
  _4 = VIEW_CONVERT_EXPR<__m128iD.5706>(_3);

But misses the conversion
