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/cc/cc51007.a | 305 +++++++++++++++++++++++++++++ 1 file changed, 305 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cc/cc51007.a (limited to 'gcc/testsuite/ada/acats/tests/cc/cc51007.a') diff --git a/gcc/testsuite/ada/acats/tests/cc/cc51007.a b/gcc/testsuite/ada/acats/tests/cc/cc51007.a new file mode 100644 index 000000000..d8f78779d --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cc/cc51007.a @@ -0,0 +1,305 @@ +-- CC51007.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 objects +-- and components of the formal derived type and its nonabstract +-- descendants may be declared and allocated, as may nonabstract +-- functions returning these types, and that aggregates of nonabstract +-- descendants of the formal derived type are legal. Check that calls to +-- the abstract primitive subprograms of the ancestor dispatch to the +-- bodies corresponding to the tag of the actual parameters. +-- +-- TEST DESCRIPTION: +-- Although the ancestor type is abstract and has abstract primitive +-- subprograms, these subprograms, when inherited by a formal nonabstract +-- derived type, are not abstract, since the formal derived type is a +-- nonabstract private extension. +-- +-- Thus, derivatives of the formal derived type need not be abstract, +-- and both the formal derived type and its derivatives are considered +-- nonabstract types. +-- +-- This test verifies that the restrictions placed on abstract types do +-- not apply to the formal derived type or its derivatives. Specifically, +-- objects of, components of, allocators of, and nonabstract functions +-- returning the formal derived type or its derivatives are legal. In +-- addition, the test verifies that a call within the instance to a +-- primitive subprogram of the (abstract) ancestor type dispatches to +-- the body corresponding to the tag of the actual parameter. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 23 Dec 94 SAIC Deleted illegal extension aggregate.
