/**
* @file
* @ingroup powerpc_virtex5
* @brief C Overhead definitions
*/
/*
*
* 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.

/*
* Updated for a 25MHz Papyrus by Andrew Bray <andy@i-cubed.co.uk>
*
* 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).
