-- DESCRIPTION:

-- This subprogram is the ASR used to measure and report the
-- execution time of a SIGNAL_SEND to SELF. Before it exits
-- it starts the timer so that the execution time required to
-- exit from an ASR back to the same task can be measured.

-- DESCRIPTION:
--
-- This subprogram is the ASR which sets up for a preemptive
-- return from an ASR. Before it exits it starts the timer
-- so that the execution time required to exit from an ASR
-- and transfer control to the another task can be measured.

-- DESCRIPTION:

-- This RTEMS task is responsible for measuring and reporting

--

-- DESCRIPTION:
--
-- This subprogram is the ASR for TASK_2. It performs no actions.

);
pragma Convention (C, PROCESS_ASR_FOR_TASK_2);
--
-- TASK_2
--
-- DESCRIPTION:
--
-- This RTEMS task is used as the recipient of a SIGNAL_SEND.
-- After establishing an ASR, it suspends itself to insure
-- that it does not execute again.
--
procedure TASK_2 (
ARGUMENT : in RTEMS.TASKS.ARGUMENT
);
pragma Convention (C, TASK_2);
--
-- TASK_3
--
-- DESCRIPTION:
--
-- This RTEMS task is used as the recipient of a preemptive
-- SIGNAL_SEND. This task suspends itself and is resumed by
-- an ASR for TASK_1. Once the task executes, it stops the
-- timer and reports the execution time for a preemptive
-- return from an ASR.
