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/cc51b03.a | 258 +++++++++++++++++++++++++++++ 1 file changed, 258 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cc/cc51b03.a (limited to 'gcc/testsuite/ada/acats/tests/cc/cc51b03.a') diff --git a/gcc/testsuite/ada/acats/tests/cc/cc51b03.a b/gcc/testsuite/ada/acats/tests/cc/cc51b03.a new file mode 100644 index 000000000..0cbeeb46f --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cc/cc51b03.a @@ -0,0 +1,258 @@ +-- CC51B03.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).

An +-- indefinite subtype is either: +-- a) An unconstrained array subtype. +-- b) A subtype with unknown discriminants (this includes class-wide +-- types). +-- c) A subtype with unconstrained discriminants without defaults. +-- +-- The possible forms of indefinite formal subtype are as follows: +-- +-- Formal derived types: +-- X - Ancestor is an unconstrained array type +-- * - Ancestor is a discriminated record type without defaults +-- X - Ancestor is a discriminated tagged type +-- * - Ancestor type has unknown discriminants +-- - Formal type has an unknown discriminant part +-- * - Formal type has a known discriminant part +-- +-- Formal private types: +-- - Formal type has an unknown discriminant part +-- * - Formal type has a known discriminant part +-- +-- The formal subtypes preceded by an 'X' above are not covered, because +-- other rules prevent a definite subtype from being passed as an actual. +-- The formal subtypes preceded by an '*' above are not covered, because +-- 'Definite is less likely to be used for these formals. +-- +-- The following kinds of actuals are passed to various of the formal +-- types listed above: +-- +-- - Undiscriminated type +-- - Type with defaulted discriminants +-- - Type with undefaulted discriminants +-- - Class-wide type +-- +-- A typical usage of S'Definite might be algorithm selection in a +-- generic I/O package, e.g., the use of fixed-length or variable-length +-- records depending on whether the actual is definite or indefinite. +-- In such situations, S'Definite would appear in if conditions or other +-- contexts requiring a boolean expression. This test checks S'Definite +-- in such usage contexts but, for brevity, omits any surrounding +-- usage code. +-- +-- TEST FILES: +-- The following files comprise this test: +-- +-- FC51B00.A +-- -> CC51B03.A +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + +with FC51B00; -- Indefinite subtype declarations. +package CC51B03_0 is + + -- + -- Formal private type cases: + -- + + generic + type Formal (<>) is private; -- Formal has unknown + package PrivateFormalUnknownDiscriminants is -- discriminant part. + function Is_Definite return Boolean; + end PrivateFormalUnknownDiscriminants; + + + -- + -- Formal derived type cases: + -- + + generic + type Formal (<>) is new FC51B00.Vector -- Formal has an unknown disc. + with private; -- part; ancestor is tagged. + package TaggedAncestorUnknownDiscriminants is + function Is_Definite return Boolean; + end TaggedAncestorUnknownDiscriminants; + + +end CC51B03_0; + + + --==================================================================-- + + +package body CC51B03_0 is + + package body PrivateFormalUnknownDiscriminants is + function Is_Definite return Boolean is + begin + if Formal'Definite then -- Attribute used in "if" + -- ...Execute algorithm #1... -- condition inside subprogram. + return True; + else + -- ...Execute algorithm #2... + return False; + end if; + end Is_Definite; + end PrivateFormalUnknownDiscriminants; + + + package body TaggedAncestorUnknownDiscriminants is + function Is_Definite return Boolean is + begin + return Formal'Definite; -- Attribute used in return + end Is_Definite; -- statement inside subprogram. + end TaggedAncestorUnknownDiscriminants; + + +end CC51B03_0; + + + --==================================================================-- + + +with FC51B00; +package CC51B03_1 is + + subtype Spin_Type is Natural range 0 .. 3; + + type Extended_Vector (Spin : Spin_Type) is -- Tagged type with + new FC51B00.Vector with null record; -- discriminant (indefinite). + + +end CC51B03_1; + + + --==================================================================-- + + +with FC51B00; -- Indefinite subtype declarations. +with CC51B03_0; -- Generic package declarations. +with CC51B03_1; + +with Report; +procedure CC51B03 is + + -- + -- Instances for formal private type with unknown discriminants: + -- + + package PrivateFormal_UndiscriminatedTaggedActual is new + CC51B03_0.PrivateFormalUnknownDiscriminants (FC51B00.Vector); + + package PrivateFormal_ClassWideActual is new + CC51B03_0.PrivateFormalUnknownDiscriminants (FC51B00.Vector'Class); + + package PrivateFormal_DiscriminatedTaggedActual is new + CC51B03_0.PrivateFormalUnknownDiscriminants (FC51B00.Square_Pair); + + package PrivateFormal_DiscriminatedUndefaultedRecordActual is new + CC51B03_0.PrivateFormalUnknownDiscriminants (FC51B00.Square); + + + subtype Length is Natural range 0 .. 20; + type Message (Len : Length := 0) is record -- Record type with defaulted + Text : String (1 ..
