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/cc51001.a | 186 +++++++++++++++++++++++++++++ 1 file changed, 186 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cc/cc51001.a (limited to 'gcc/testsuite/ada/acats/tests/cc/cc51001.a') diff --git a/gcc/testsuite/ada/acats/tests/cc/cc51001.a b/gcc/testsuite/ada/acats/tests/cc/cc51001.a new file mode 100644 index 000000000..6aa76a6f8 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cc/cc51001.a @@ -0,0 +1,186 @@ +-- CC51001.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 derived type may have an unknown +-- discriminant part. Check that the ancestor type in a formal derived +-- type definition may be a tagged type, and that the actual parameter +-- may be a descendant of the ancestor type. Check that the formal derived +-- type belongs to the derivation class rooted at the ancestor type; +-- specifically, that components of the ancestor type may be referenced +-- within the generic. Check that if a formal derived subtype is +-- indefinite then the actual may be either definite or indefinite. +-- +-- TEST DESCRIPTION: +-- Define a class of tagged types with a definite root type. Extend the +-- root type with a discriminated component. Since discriminants of +-- tagged types may not have defaults, the type is indefinite. +-- +-- Extend the extension with a second discriminated component, but with +-- a new discriminant part. Declare a generic package with a formal +-- derived type using the root type of the class as ancestor, and an +-- unknown discriminant part. Declare an operation in the generic which +-- accesses the common component of types in the class. +-- +-- In the main program, instantiate the generic with each type in the +-- class and verify that the operation correctly accesses the common +-- component. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + +package CC51001_0 is -- Root type for message class. + + subtype Msg_String is String (1 .. 20); + + type Msg_Type is tagged record -- Root type of + Text : Msg_String := (others => ' '); -- class (definite). + end record; + +end CC51001_0; + + +-- No body for CC51001_0. + + + --==================================================================-- + + +with CC51001_0; -- Root type for message class. +package CC51001_1 is -- Extensions to message class. + + subtype Source_Length is Natural range 0 .. 10; + + type From_Msg_Type (SLen : Source_Length) is -- Direct derivative + new CC51001_0.Msg_Type with record -- of root type + From : String (1 ..
