Confirmed, the problem is that DOM does:
  D.1192 = (unsigned int) i;
  D.1194 = (float * restrict) D.1192 * 4B;
  *(aa2 + D.1194) = *(a2 + D.1194);
  *(bb2 + D.1194) = *(b2 + D.1194);

Note how we use D.1194 in all three places. for PPC this is the correct thing 
to do but not for x86 which 
has three operands loads.
