   Seems I misread the standard, missing out on clause 17.4 paragraph 5,   
   which states   
      
   In a procedure other than IEEE_SET_ROUNDING_MODE or IEEE_SET_STATUS,   
   the processor shall not change the rounding modes on entry, and   
   on return shall ensure that the rounding modes are the same as   
   they were on entry.   
      
   So, that part of my premise was wrong. Sorry.
