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/cxaa006.a | 285 ++++++++++++++++++++++++++++ 1 file changed, 285 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cxa/cxaa006.a (limited to 'gcc/testsuite/ada/acats/tests/cxa/cxaa006.a') diff --git a/gcc/testsuite/ada/acats/tests/cxa/cxaa006.a b/gcc/testsuite/ada/acats/tests/cxa/cxaa006.a new file mode 100644 index 000000000..518d43b89 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cxa/cxaa006.a @@ -0,0 +1,285 @@ +-- CXAA006.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 is the case in a typesetting +-- environment where text is compressed and split between lines of a +-- bounded length. +-- +-- The procedure Put will break string parameters placed in the file at +-- the point of the line length. Two examples are demonstrated in this +-- test, one being the case where only one column remains on a line, and +-- the other being the case where a larger portion of the line remains +-- unfilled, but still not sufficient to contain the entire output +-- string. +-- +-- During the course of the test, the file is reset to Append_File mode, +-- and the bounded line length is modified for different lines of the +-- file. +-- +-- APPLICABILITY CRITERIA: +-- This test is applicable to all implementations that support Text_IO +-- processing and external files. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 25 Feb 97 PWB.CTA Allowed for non-support of some IO operations +--! + +with Ada.Text_IO; +with Report; + +procedure CXAA006 is + + A_Bounded_File : Ada.Text_IO.File_Type; + Bounded_File_Name : constant String := + Report.Legal_File_Name ( Nam => "CXAA006" ); + Incomplete : exception; + +begin + + Report.Test ("CXAA006", "Check that procedure Put will correctly " & + "output string items to a bounded line " & + "length text file of mode Append_File"); + + Test_for_Text_IO_Support: + begin + +-- An application creates a text file in mode Append_File, with the intention +-- of using the procedure Put to compress variable length string data into the +-- file in the most efficient manner possible. + + Ada.Text_IO.Create (File => A_Bounded_File, + Mode => Ada.Text_IO.Append_File, + Name => Bounded_File_Name); + exception + when Ada.Text_IO.Use_Error | Ada.Text_IO.Name_Error => + Report.Not_Applicable + ( "Files not supported - Create with Append_File for Text_IO" ); + raise Incomplete; + end Test_For_Text_IO_Support; + + Operational_Test_Block: + declare + Twelve_Characters : constant String := "12Characters"; + Nineteen_Characters : constant String := "Nineteen_Characters"; + TC_Line : Natural := 0; + + function TC_Mode_Selection (Selector : Integer) + return Ada.Text_IO.File_Mode is + begin + case Selector is + when 1 => return Ada.Text_IO.In_File; + when 2 => return Ada.Text_IO.Out_File; + when others => return Ada.Text_IO.Append_File; + end case; + end TC_Mode_Selection; + + begin + +-- The application sets the line length of the file to be bound at 20.
