Jerry, you may already know about -fdump-parse-tree and 
-fdump-tree-original.  In particular, -fdump-tree-original
gives

  MAIN__ ()
  {
     static int4 i = 12;
     static real4 r = 3.1400001049041748046875e+0;
....
  {
    real8 D.469;

    D.469 = (real8) r;
    _gfortran_transfer_real (&D.469, 8);
  }
