So what seems to be happening is PRE is pull out the following from the loop:

  pretmp_250 = MEM[(float *)_2 + 4294933760B + ivtmp.159_57 * 1];
  _22 = (void *) ivtmp.140_79;
  pretmp_253 = MEM[(float *)_22 + 4294934276B];
  pretmp_257 = MEM[(float *)_22 + 4294900220B];
  pretmp_259 = MEM[(float *)_22 + 4294933244B];
  pretmp_261 = MEM[(float *)_22 + 4294933760B];
