/*  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
 *         all calling overhead including passing of arguments.
 *
 *
 * These are the figures tmoverhd.exe reported with egcs-980205 -O3
 * on a Diesner OktagonSH/Amos-2.1 board with SH7032/20MHz
 *
 * These results are assumed to be applicable to most SH7032/20MHz boards
