       3     This test ensures that the shorter LEA instruction is used in preference
       4     to the longer ADD instruction.
       5  
       6     This preference is applicable to ColdFire only.  On CPU32, we can
       7     use a sequence of two ADDQ instructions, which is faster than the
       8     LEA instruction.  */
