 	The problem is easy_fp_constant():
 
   /* If we are using V.4 style PIC, consider all constants to be hard.  */
   if (flag_pic && DEFAULT_ABI == ABI_V4)
     return 0;
 
 This means that "input_operand" predicate fails for movdf_hardfloat32 when
 presented with const_double:DF.  I'm not sure what's suppose to save us at
 that point.
