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/c4/c460005.a | 260 +++++++++++++++++++++++++++++ 1 file changed, 260 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/c4/c460005.a (limited to 'gcc/testsuite/ada/acats/tests/c4/c460005.a') diff --git a/gcc/testsuite/ada/acats/tests/c4/c460005.a b/gcc/testsuite/ada/acats/tests/c4/c460005.a new file mode 100644 index 000000000..95b14a9a2 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/c4/c460005.a @@ -0,0 +1,260 @@ +-- C460005.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).

In all cases, a +-- check is made that Constraint_Error is raised if the tag of the +-- operand does not identify a specific type covered by or descended +-- from the target type, and not raised otherwise. +-- +-- For the cases where the view conversion is the left side of an +-- assignment statement, and Constraint_Error should not be raised, +-- an additional check is made that only the corresponding portion +-- of the operand is updated by the assignment. For example: +-- +-- type T is tagged record +-- C1 : Integer := 0; +-- end record; +-- +-- type DT is new T with record +-- C2 : Integer := 0; +-- end record; +-- +-- A : T := (C1 => 5); +-- B : DT := (C1 => 0, C2 => 10); +-- CWDT : T'Class := B; +-- +-- T(CWDT) := A; -- Updates component C1; C2 remains unchanged. +-- -- Value of CWDT is (C1 => 5, C2 => 10). +-- +-- +-- CHANGE HISTORY: +-- 31 Jul 95 SAIC Initial prerelease version. +-- 22 Apr 96 SAIC ACVC 2.1: Added a check for correct tag. +-- 08 Sep 96 SAIC ACVC 2.1: Modified Report.Test. +-- +--!
