+ *  This include file has defines to represent the overhead associated
+ *  with calling a particular directive from C.  These are used in the
+ *  Timing Test Suite to ignore the overhead required to pass arguments
+ *  to directives.  On some CPUs and/or target boards, this overhead
+ *  is significant and makes it difficult to distinguish internal
+ *  RTEMS execution time from that used to call the directive.
+ *  This file should be updated after running the C overhead timing
+ *  test.  Once this update has been performed, the RTEMS Time Test
+ *  Suite should be rebuilt to account for these overhead times in the
+ *  timing results.
+ *
+ *  NOTE:  If these are all zero, then the times reported include all
+ *         all calling overhead including passing of arguments.
+ *
+ *
+ * These are the figures tmoverhd.exe reported with gcc-2.95.1 -O4 
+ * on a Hitachi SH7045F Evaluation Board with SH7045F at 29 MHz
+ *
