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/c953003.a | 189 +++++++++++++++++++++++++++++ 1 file changed, 189 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/c9/c953003.a (limited to 'gcc/testsuite/ada/acats/tests/c9/c953003.a') diff --git a/gcc/testsuite/ada/acats/tests/c9/c953003.a b/gcc/testsuite/ada/acats/tests/c9/c953003.a new file mode 100644 index 000000000..4ac91169e --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/c9/c953003.a @@ -0,0 +1,189 @@ +-- C953003.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).

As part of the servicing of this entry +-- call the call is passed through the remaining entries of the +-- protected object by using internal requeues. The protected +-- object checks that no other entry call is accepted until +-- after all the internal requeuing has completed. +-- +-- +-- CHANGE HISTORY: +-- 12 JAN 96 SAIC Initial version for 2.1 +-- +--! + +with Report; +procedure C953003 is + Verbose : constant Boolean := False; + + Order_Error : Boolean := False; + + Max_Tasks : constant := 10; -- total number of tasks + Max_Entries : constant := 4; -- number of entries in Main_PO + Note_Cnt : Integer := 0; + Note_Order : array (1..Max_Tasks*Max_Entries) of Integer; +begin + Report.Test ("C953003", + "Check that the servicing of entry queues handles all" & + " open entries as part of a single protected operation," & + " including those resulting from an internal requeue"); + declare + task type Assault_PO is + entry Take_ID (Id : Integer); + end Assault_PO; + + Marines : array (1 ..
