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/c3/c3a0007.a | 234 +++++++++++++++++++++++++++++ 1 file changed, 234 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/c3/c3a0007.a (limited to 'gcc/testsuite/ada/acats/tests/c3/c3a0007.a') diff --git a/gcc/testsuite/ada/acats/tests/c3/c3a0007.a b/gcc/testsuite/ada/acats/tests/c3/c3a0007.a new file mode 100644 index 000000000..ff18d2f9e --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/c3/c3a0007.a @@ -0,0 +1,234 @@ +-- C3A0007.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).

Declare three primitive procedures for the type that +-- can be referred to by the access to procedure type. Use the access +-- to procedure type to initialize the component of a record. +-- +-- Extend the root type with a record extension in another package +-- specification. Declare a new primitive procedure for the extension +-- (in addition to its three inherited subprograms). +-- +-- In the main program, declare an operation for the root tagged type +-- which can be passed as an access value to change the initial value +-- of the component. Call the inherited operation indirectly by +-- dereferencing the access value to check on the initial value of the +-- extension. Call inherited operations indirectly by dereferencing +-- the access value to replace the initial value. Call the primitive +-- procedure indirectly by dereferencing the access value to modify the +-- extension. +-- +-- type Button +-- procedure Push(Button) +-- procedure Set_Response(Button,Button_Response_Ptr) +-- procedure Default_Response(Button) +-- +-- type Priority_Button (new Button) +-- procedures Push, Set_Response inherited +-- procedure Default_Response +-- procedure Set_Priority +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + +package C3A0007_0 is + + Default_Call : Boolean := False; + + type Button is tagged private; + + type Button_Response_Ptr is access procedure + (B : in out Button'Class); + + procedure Push (B : in out Button); -- to be inherited + + procedure Set_Response (B : in out Button; -- to be inherited + R : in Button_Response_Ptr); + + procedure Response (B : in out Button); -- to be inherited + +private + procedure Default_Response(B: in out Button'Class); + type Button is tagged -- root tagged type + record + Action : Button_Response_Ptr + := Default_Response'Access; + end record; +end C3A0007_0; + +with C3A0007_0; +package C3A0007_1 is + + type Priority_Button is new C3A0007_0.Button + with record + Priority : Integer := 0; + end record; + + -- Inherits procedure Push from Button + -- Inherits procedure Set_Response from Button + + -- Override procedure Response from Button + procedure Response (B : in out Priority_Button); + + -- Primitive operation of the extension + procedure Set_Priority (B : in out Priority_Button); + +end C3A0007_1; + +with C3A0007_0; +package C3A0007_2 is + + Emergency_Call : Boolean := False; + + procedure Emergency (B : in out C3A0007_0.Button'Class); +end C3A0007_2; + +----------------------------------------------------------------------------- + +with TCTouch; +package body C3A0007_0 is + + procedure Push (B : in out Button) is + begin + TCTouch.Touch( 'P' ); --------------------------------------------- P + -- Invoking subprogram designated by access value + B.Action (B); + end Push; + + + procedure Set_Response (B : in out Button; + R : in Button_Response_Ptr) is + begin + TCTouch.Touch( 'S' ); --------------------------------------------- S + -- Set procedure value in record + B.Action := R; + end Set_Response; + + + procedure Response (B : in out Button) is + begin + TCTouch.Touch( 'D' ); --------------------------------------------- D + Default_Call := True; + end Response; + + procedure Default_Response (B : in out Button'Class) is + begin + TCTouch.Touch( 'C' ); --------------------------------------------- C + Response(B); + end Default_Response; + +end C3A0007_0; + +with TCTouch; +package body C3A0007_1 is + + procedure Set_Priority (B : in out Priority_Button) is + begin + TCTouch.Touch( 's' ); --------------------------------------------- s + B.Priority := 1; + end Set_Priority; + + procedure Response (B : in out Priority_Button) is + begin + TCTouch.Touch( 'd' ); --------------------------------------------- d + end Response; + +end C3A0007_1; + +with TCTouch; +package body C3A0007_2 is + procedure Emergency (B : in out C3A0007_0.Button'Class) is + begin + TCTouch.Touch( 'E' ); ------------------------------------------- E + Emergency_Call := True; + end Emergency; +end C3A0007_2; + +----------------------------------------------------------------------------- + +with Report; +with TCTouch; + +with C3A0007_0; +with C3A0007_1; +with C3A0007_2; +procedure C3A0007 is + + Pink_Button : C3A0007_0.Button; + Green_Button : C3A0007_1.Priority_Button; + +begin + + Report.Test ("C3A0007", "Check that a call to a subprogram via an " + & "access-to-subprogram value stored in a data " + & "structure will correctly dispatch according to " + & "the tag of the class-wide parameter passed " + & "via that call" ); + + -- Call inherited operation Push to set Default_Response value + -- in the extension. + + C3A0007_1.Push (Green_Button); + TCTouch.Validate("PCd", "First Green Button Push"); + + TCTouch.Assert_Not(C3A0007_0.Default_Call, + "Incorrect Green Default_Response"); + + C3A0007_0.Push (Pink_Button); + TCTouch.Validate("PCD", "First Pink Button Push"); + + -- Call inherited operations Set_Response and Push to set + -- Emergency value in the extension. + C3A0007_1.Set_Response (Green_Button, C3A0007_2.Emergency'Access); + C3A0007_1.Push (Green_Button); + TCTouch.Validate("SPE", "Second Green Button Push"); + + TCTouch.Assert(C3A0007_2.Emergency_Call, "Incorrect Green Emergency"); + + C3A0007_0.Set_Response (Pink_Button, C3A0007_2.Emergency'Access); + C3A0007_0.Push (Pink_Button); + TCTouch.Validate("SPE", "Second Pink Button Push"); + + -- Call primitive operation to set priority value + -- in the extension. + C3A0007_1.Set_Priority (Green_Button); + TCTouch.Validate("s", "Green Button Priority"); + + TCTouch.Assert(Green_Button.Priority = 1, "Incorrect Set_Priority"); + + Report.Result; + +end C3A0007; -- cgit v1.2.3
