/* GCC was generating an ICE with the above options and -Os because
   it was putting the save of $31 in two annulled delay slots but
   there was only one restore since only one of the two saves could be
   executed.  This was correct code but it confused dwarf2cfi and
   caused it to ICE when using the -g option.  */
