-Calling Overhead File
-=====================
-
-The file ``include/coverhd.h`` contains the overhead associated with invoking
-each directive.  This overhead consists of the execution time required to
-package the parameters as well as to execute the "jump to subroutine" and
-"return from subroutine" sequence.  The intent of this file is to help separate
-the calling overhead from the actual execution time of a directive.  This file
-is only used by the tests in the RTEMS Timing Test Suite.
-
-The numbers in this file are obtained by running the "Timer
-Overhead"``tmoverhd`` test.  The numbers in this file may be 0 and no overhead
-is subtracted from the directive execution times reported by the Timing Suite.
-
-There is a shared implementation of ``coverhd.h`` which sets all of the
-overhead constants to 0.  On faster processors, this is usually the best
-alternative for the BSP as the calling overhead is extremely small.  This file
