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/cxa8003.a | 214 ++++++++++++++++++++++++++++ 1 file changed, 214 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cxa/cxa8003.a (limited to 'gcc/testsuite/ada/acats/tests/cxa/cxa8003.a') diff --git a/gcc/testsuite/ada/acats/tests/cxa/cxa8003.a b/gcc/testsuite/ada/acats/tests/cxa/cxa8003.a new file mode 100644 index 000000000..cf9b5e075 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cxa/cxa8003.a @@ -0,0 +1,214 @@ +-- CXA8003.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).

The file descriptor is passed as a parameter, along with a +-- numeric indicator for the new mode. Based on the numeric parameter, +-- a Direct_IO.Reset is performed using a File_Mode'Value transformation +-- of a string constant into a File_Mode value. An attempt to reset a +-- Direct_IO file to mode Append_File should cause an Constraint_Error +-- to be raised, as Append_File mode has not been added to Direct_IO in +-- Ada 9X. +-- +-- APPLICABILITY CRITERIA: +-- This test is applicable to all implementations supporting Direct_IO +-- files. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 19 Feb 97 PWB.CTA Allowed for non-support of Reset for certain +-- modes. +--! + +with Direct_IO; +with Report; + +procedure CXA8003 is + Incomplete : exception; + begin + + Report.Test ("CXA8003", "Check that Append_File mode has not " & + "been added to package Direct_IO"); + + Test_for_Direct_IO_Support: + declare + + subtype String_Data_Type is String (1 .. 20); + type Numeric_Data_Type is range 1 .. 512; + type Composite_Data_Type is array (1 .. 3) of String_Data_Type; + + type File_Data_Type is record + Data_Field_1 : String_Data_Type; + Data_Field_2 : Numeric_Data_Type; + Data_Field_3 : Composite_Data_Type; + end record; + + package Dir_IO is new Direct_IO (File_Data_Type); + + Data_File : Dir_IO.File_Type; + Dir_Filename : constant String := Report.Legal_File_Name; + + begin + + -- An application creates a text file with mode Out_File. + -- Use_Error will be raised if Direct_IO operations or external + -- files are not supported. + + Dir_IO.Create (Data_File, + Dir_IO.Out_File, + Dir_Filename); + + Change_File_Mode: + declare + + TC_Append_Test_Executed : Boolean := False; + + type Mode_Selection_Type is ( A, I, IO, O ); + + + procedure Change_Mode (File : in out Dir_IO.File_Type; + To : in Mode_Selection_Type) is + begin + case To is + when A => + TC_Append_Test_Executed := True; + Dir_IO.Reset + (File, Dir_IO.File_Mode'Value("Append_File")); + when I => + begin + Dir_IO.Reset + (File, Dir_IO.File_Mode'Value("In_File")); + exception + when Dir_IO.Use_Error => + Report.Not_Applicable + ("Reset to In_File not supported: Direct_IO"); + raise Incomplete; + end; + when IO => + begin + Dir_IO.Reset + (File, Dir_IO.File_Mode'Value("Inout_File")); + exception + when Dir_IO.Use_Error => + Report.Not_Applicable + ("Reset to InOut_File not supported: Direct_IO"); + raise Incomplete; + end; + when O => + begin + Dir_IO.Reset + (File, Dir_IO.File_Mode'Value("Out_File")); + exception + when Dir_IO.Use_Error => + Report.Not_Applicable + ("Reset to Out_File not supported: Direct_IO"); + raise Incomplete; + end; + end case; + end Change_Mode; + + + begin + + -- At some point in the processing, the application may call a + -- procedure to change the mode of the file (perhaps for + -- additional data entry, data verification, etc.).
