Abstract
Instrumentation statistics are tallied at the procedure level in instrumentation stack frames corresponding to subroutine stack frames. Elapsed CPU time for each entry into a procedure is computed and accumulated into a statistics table corresponding to that procedure. Also accumulated into that statistics table are the accumulated elapsed execution times of the subroutines called by this procedure. These values are initially accumulated into the instrumentation stack frame for each subroutine's parent upon subroutine exit, and then accumulated into the statistics table upon subroutine exit of the parent. Elapsed CPU time is computed by subtracting CPU time of last dispatch from the current hardware clock, then adding this to an accumulated CPU time at the time of dispatch.
