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/cc51002.a | 198 +++++++++++++++++++++++++++++ 1 file changed, 198 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cc/cc51002.a (limited to 'gcc/testsuite/ada/acats/tests/cc/cc51002.a') diff --git a/gcc/testsuite/ada/acats/tests/cc/cc51002.a b/gcc/testsuite/ada/acats/tests/cc/cc51002.a new file mode 100644 index 000000000..1083d18a8 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cc/cc51002.a @@ -0,0 +1,198 @@ +-- CC51002.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).

Provide a default expression for a non-tagged +-- parameter of the subprogram. Declare a library-level generic subprogram +-- with a formal derived type using the root type as ancestor. Call +-- the primitive subprogram of the root type using named association for +-- the tagged parameter, and provide no actual for the defaulted +-- parameter. Extend the root type in a second package and override the +-- root type's subprogram with one which has different parameter names +-- and no default expression for the non-tagged parameter. Instantiate +-- the generic subprogram for each of the tagged types in the class and +-- call the instances. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + +package CC51002_0 is -- Root message type and operations. + + type Recipients is (None, Root, Sysop, Local, Remote); + + type Msg_Type is tagged record -- Root type of + Text : String (1 .. 10); -- class. + end record; + + function Send (Msg : in Msg_Type; -- Primitive + To : Recipients := Local) return Boolean; -- subprogram. + + -- ...Other message operations. + +end CC51002_0; + + + --==================================================================-- + + +package body CC51002_0 is + + -- The implementation of Send is purely artificial; the validity of + -- its implementation in the context of the abstraction is irrelevant to + -- the feature being tested. + + function Send (Msg : in Msg_Type; + To : Recipients := Local) return Boolean is + begin + return (Msg.Text = "Greetings!" and To = Local); + end Send; + +end CC51002_0; + + + --==================================================================-- + + +with CC51002_0; -- Root message type and operations. +generic -- Message class function. + type Msg_Block is new CC51002_0.Msg_Type with private; +function CC51002_1 (M : in Msg_Block) return Boolean; + + + --==================================================================-- + + +function CC51002_1 (M : in Msg_Block) return Boolean is + Okay : Boolean := False; +begin + + -- The call to Send below uses the ancestor type's parameter name, which + -- should be legal even if the actual subprogram called does not have a + -- parameter of that name.
