/*  coverhd.h
 *
 *  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 calling overhead including passing of arguments.

 *
 *  Units are 100ns.
 *
 *  These numbers are of questionable use, as they are developed by calling
 *  the routine many times, thus getting its entry veneer into the (small)
 *  cache on the 403GA.  This in general is not true of the RTEMS timing
 *  tests, which usually call a routine only once, thus having no cache loaded
 *  advantage.
 *
 *  Whether the directive times are useful after deducting the function call
 *  overhead is also questionable.  The user is more interested generally
 *  in the total cost of a directive, not the cost if the procedure call
 *  is inlined!  (In general this is not true).
