 *
3
 *  This include file has defines to represent the overhead associated
4
 *  with calling a particular directive from C.  These are used in the
5
 *  Timing Test Suite to ignore the overhead required to pass arguments
6
 *  to directives.  On some CPUs and/or target boards, this overhead
7
 *  is significant and makes it difficult to distinguish internal
8
 *  RTEMS execution time from that used to call the directive.
9
 *  This file should be updated after running the C overhead timing
10
 *  test.  Once this update has been performed, the RTEMS Time Test
11
 *  Suite should be rebuilt to account for these overhead times in the
12
 *  timing results.
13
 *
14
 *  NOTE:  If these are all zero, then the times reported include
15
 *         all calling overhead including passing of arguments.

28
 *  Updated for a 25MHz Papyrus by Andrew Bray <andy@i-cubed.co.uk>
29
 *
30
 *  Units are 100ns.
31
 *
32
 *  These numbers are of questionable use, as they are developed by calling
33
 *  the routine many times, thus getting its entry veneer into the (small)
34
 *  cache on the 403GA.  This in general is not true of the RTEMS timing
35
 *  tests, which usually call a routine only once, thus having no cache loaded
36
 *  advantage.
37
 *
38
 *  Whether the directive times are useful after deducting the function call
39
 *  overhead is also questionable.  The user is more interested generally
40
 *  in the total cost of a directive, not the cost if the procedure call
41
 *  is inlined!  (In general this is not true).
