From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- gcc/testsuite/ada/acats/tests/c9/c974001.a | 152 +++++++++++++++++++++++++++++ 1 file changed, 152 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/c9/c974001.a (limited to 'gcc/testsuite/ada/acats/tests/c9/c974001.a') diff --git a/gcc/testsuite/ada/acats/tests/c9/c974001.a b/gcc/testsuite/ada/acats/tests/c9/c974001.a new file mode 100644 index 000000000..04ac93e6d --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/c9/c974001.a @@ -0,0 +1,152 @@ +-- C974001.A +-- +-- +-- Grant of Unlimited Rights +-- +-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687, +-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained +-- unlimited rights in the software and documentation contained herein. +-- Unlimited rights are defined in DFAR 252.227-7013(a)(19).

Parameterize +-- the accept statement with the time to be used in the delay. Simulate a +-- time-consuming calculation by declaring a procedure containing an +-- infinite loop. Call this procedure in the abortable part. +-- +-- The delay will expire before the abortable part completes, at which +-- time the abortable part is aborted, and the sequence of statements +-- following the triggering statement is executed. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + +with Report; +with ImpDef; + +procedure C974001 is + + + --========================================================-- + + -- Medium length delay + Allotted_Time : constant Duration := ImpDef.Switch_To_New_Task; + + Calculation_Canceled : exception; + + + Count : Integer := 1234; + + procedure Lengthy_Calculation is + begin + -- Simulate a non-converging calculation. + loop -- Infinite loop. + Count := (Count + 1) mod 10; + delay ImpDef.Minimum_Task_Switch; -- allow other task + end loop; + end Lengthy_Calculation; + + + --========================================================-- + + + task type Timed_Calculation is + entry Calculation (Time_Limit : in Duration); + end Timed_Calculation; + + + task body Timed_Calculation is + -- + begin + loop + select + accept Calculation (Time_Limit : in Duration) do + + -- -- + -- Asynchronous select is tested here -- + -- -- + + select + delay Time_Limit; -- Time_Limit is not up yet, so + -- Lengthy_Calculation starts. + + raise Calculation_Canceled; -- This is executed after + -- Lengthy_Calculation aborted. + then abort + Lengthy_Calculation; -- Delay expires before complete, + -- so this call is aborted. + + -- Check that the whole of the abortable part is aborted, + -- not just the statement in the abortable part that was + -- executing at the time + Report.Failed ("Abortable part not aborted"); + + end select; + + Report.Failed ("Triggering alternative sequence of " & + "statements not executed"); + + exception -- New Ada 9x: handler within accept + when Calculation_Canceled => + if Count = 1234 then + Report.Failed ("Abortable part did not execute"); + end if; + end Calculation; + or + terminate; + end select; + end loop; + exception + when others => + Report.Failed ("Unexpected exception in Timed_Calculation task"); + end Timed_Calculation; + + + --========================================================-- + + +begin -- Main program. + + Report.Test ("C974001", "Asynchronous Select: Trigger is delay_relative" & + " which completes before abortable part"); + + declare + Timed : Timed_Calculation; -- Task. + begin + Timed.Calculation (Time_Limit => Allotted_Time); -- Asynchronous select + -- inside accept block. + exception + when Calculation_Canceled => + null; -- expected behavior + end; + + Report.Result; + +end C974001; -- cgit v1.2.3
