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/c3/c340a02.a | 221 +++++++++++++++++++++++++++++ 1 file changed, 221 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/c3/c340a02.a (limited to 'gcc/testsuite/ada/acats/tests/c3/c340a02.a') diff --git a/gcc/testsuite/ada/acats/tests/c3/c340a02.a b/gcc/testsuite/ada/acats/tests/c3/c340a02.a new file mode 100644 index 000000000..2dd8f175c --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/c3/c340a02.a @@ -0,0 +1,221 @@ +-- C340A02.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).

Check that the formal type may be further extended with a +-- record extension in the generic package. +-- +-- Check that, in the instance, the record extension inherits the +-- user-defined primitive subprograms of the tagged actual, including +-- those inherited by the actual from its parent. +-- +-- TEST DESCRIPTION: +-- Declare a tagged type and an associated primitive subprogram in a +-- package specification (foundation code). Declare a record extension +-- of the tagged type and an associated primitive subprogram in a second +-- package specification. Declare a generic package which takes a tagged +-- type as a formal parameter, and then extends it with a record +-- extension (foundation code). +-- +-- Instantiate the generic package with the record extension from the +-- second package (the "generic" extension should now have inherited +-- the primitive subprograms of the record extension from the second +-- package). +-- +-- In the main program, call the primitive subprograms inherited by the +-- "generic" extension. There are two: (1) Create_Book, declared for +-- the root tagged type in the first package (inherited by the record +-- extension of the second package, and then in turn by the "generic" +-- extension), and (2) Update_Pages, declared for the record extension +-- in the second package. Verify the correctness of the components. +-- +-- TEST FILES: +-- This test consists of the following files: +-- +-- F340A000.A +-- F340A001.A +-- => C340A02.A +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 12 Jun 96 SAIC ACVC 2.1: Modified prologue.
