--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
One thing I Noticed:

  _51 = _45 ? _50 : 0;
...
  _47 = _6 + _51;
...

This could be done as:
  _51 = _6 + _50;
  _47 = _45 ? _51 : _6;

Which should change:
        it      hi
        movhi   r4, #0
        add     r4, r4, r5
into:
        it      hi
        addhi   r4, r4, r5
