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/cb/cb41002.a | 283 +++++++++++++++++++++++++++++ 1 file changed, 283 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cb/cb41002.a (limited to 'gcc/testsuite/ada/acats/tests/cb/cb41002.a') diff --git a/gcc/testsuite/ada/acats/tests/cb/cb41002.a b/gcc/testsuite/ada/acats/tests/cb/cb41002.a new file mode 100644 index 000000000..1b3898154 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cb/cb41002.a @@ -0,0 +1,283 @@ +-- CB41002.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).

The exception will be raised using the +-- 'Identity attribute as a parameter to the Raise_Exception procedure, +-- and an associated message string will be provided. The exception +-- will be handled, and the message associated with the occurrence will +-- be compared to the original source message (non-default). +-- +-- The test also includes a simulated logging procedure +-- (Check_Exception_Information) that checks that Exception_Information +-- can be called. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 22 Jun 00 RLB Added a check at Exception_Information can be +-- called. +-- +--! + +with Report; +with Ada.Exceptions; + +procedure CB41002 is +begin + + Report.Test ("CB41002", "Check that the message string input parameter " & + "in a call to the Raise_Exception procedure is " & + "associated with the raised exception " & + "occurrence, and that the message string can " & + "be obtained using the Exception_Message " & + "function with the associated " & + "Exception_Occurrence object.
