/* These values were measured on a PA8500 using the system compiler version
   B.11.11.04.  Measurements on PA8000 with system compiler version A.10.32.30
   give very similar values, GCC 3.1 will probably give somewhat different
   results (earlier GCC versions do not support HPPA in 64-bit mode).  */
