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/cxa/cxaa012.a | 167 ++++++++++++++++++++++++++++ 1 file changed, 167 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cxa/cxaa012.a (limited to 'gcc/testsuite/ada/acats/tests/cxa/cxaa012.a') diff --git a/gcc/testsuite/ada/acats/tests/cxa/cxaa012.a b/gcc/testsuite/ada/acats/tests/cxa/cxaa012.a new file mode 100644 index 000000000..07523b441 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cxa/cxaa012.a @@ -0,0 +1,167 @@ +-- CXAA012.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).

This results in the +-- raising of Mode_Error exceptions, which is handled within blocks +-- embedded in the test. +-- A count is kept to ensure that each anticipated exception is in fact +-- raised and handled properly. +-- +-- APPLICABILITY CRITERIA: +-- This test is applicable only to implementations that support text +-- files. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 27 Feb 97 PWB.CTA Allowed for non-support of some IO operations +--! + +with Ada.Text_IO; +with Report; + +procedure CXAA012 is + use Ada; + Text_File : Text_IO.File_Type; + Text_Filename : constant String := + Report.Legal_File_Name ( Nam => "CXAA012" ); + Incomplete : exception; +begin + + Report.Test ("CXAA012", "Check that the exception Mode_Error is " & + "raised when an attempt is made to read " & + "from (perform a Get_Line) or use the " & + "predefined End_Of_File function on a " & + "text file with mode Append_File"); + + Test_for_Text_IO_Support: + begin + + -- Use_Error or Name_Error will be raised if Text_IO operations + -- or external files are not supported. + + Text_IO.Create (Text_File, Text_IO.Out_File, Text_Filename); + + exception + when Text_IO.Use_Error | Text_IO.Name_Error => + Report.Not_Applicable + ( "Files not supported - Create as Out_File for Text_IO" ); + raise Incomplete; + end Test_for_Text_IO_Support; + + -- The application writes some amount of data to the file. + + Text_IO.Put_Line (Text_File, "Data entered into the file"); + + Text_IO.Close (Text_File); + + Operational_Test_Block: + declare + TC_Number_Of_Forced_Mode_Errors : constant Natural := 2; + TC_Mode_Errors : Natural := 0; + begin + + Text_IO.Open (Text_File, Text_IO.Append_File, Text_Filename); + + Test_for_Reading: + declare + TC_Data : String (1..80); + TC_Length : Natural := 0; + begin + +-- During the course of its processing, the application may become confused +-- and erroneously attempt to read data from the file that is currently in +-- Append_File mode (instead of the anticipated In_File mode). +-- This would result in the raising of Mode_Error. + + Text_IO.Get_Line (Text_File, TC_Data, TC_Length); + Report.Failed ("Exception not raised by Get_Line"); + +-- An exception handler present within the application handles the exception +-- and processing can continue. + + exception + when Text_IO.Mode_Error => + TC_Mode_Errors := TC_Mode_Errors + 1; + when others => + Report.Failed ("Exception in Get_Line processing"); + end Test_for_Reading; + + + Test_for_End_Of_File: + declare + TC_End_Of_File : Boolean; + begin + +-- Again, during the course of its processing, the application attempts to +-- call the End_Of_File function for the file that is currently in +-- Append_File mode (instead of the anticipated In_File mode). + + TC_End_Of_File := Text_IO.End_Of_File (Text_File); + Report.Failed ("Exception not raised by End_Of_File"); + +-- Once again, an exception handler present within the application handles +-- the exception and processing continues. + + exception + when Text_IO.Mode_Error => + TC_Mode_Errors := TC_Mode_Errors + 1; + when others => + Report.Failed("Exception in End_Of_File processing"); + end Test_for_End_Of_File; + + + if (TC_Mode_Errors /= TC_Number_Of_Forced_Mode_Errors) then + Report.Failed ("Incorrect number of exceptions handled"); + end if; + + end Operational_Test_Block; + + -- Delete the external file. + if Text_IO.Is_Open (Text_File) then + Text_IO.Delete (Text_File); + else + Text_IO.Open (Text_File, Text_IO.In_File, Text_Filename); + Text_IO.Delete (Text_File); + end if; + + Report.Result; + +exception + when Incomplete => + Report.Result; + when others => + Report.Failed ( "Unexpected exception" ); + Report.Result; + +end CXAA012; -- cgit v1.2.3
