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/cxaa005.a | 292 ++++++++++++++++++++++++++++ 1 file changed, 292 insertions(+) create mode 100644 gcc/testsuite/ada/acats/tests/cxa/cxaa005.a (limited to 'gcc/testsuite/ada/acats/tests/cxa/cxaa005.a') diff --git a/gcc/testsuite/ada/acats/tests/cxa/cxaa005.a b/gcc/testsuite/ada/acats/tests/cxa/cxaa005.a new file mode 100644 index 000000000..7b2a0bc39 --- /dev/null +++ b/gcc/testsuite/ada/acats/tests/cxa/cxaa005.a @@ -0,0 +1,292 @@ +-- CXAA005.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).

For an unbounded text file written with Put procedures +-- only (not Put_Line), the line number should not be incremented by +-- subsequent calls to Put in Append_File mode. Only the column number +-- should be incremented based on the length of the string parameter +-- placed in the file. If a call to Put with a null string argument is +-- made, no change to the line or column number should occur, and no +-- element(s) should be added to the file, so that there would be no +-- measurable change to 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 +-- 24 Feb 97 CTA.PWB Allowed for non-support of some IO operations. +--! + +with Ada.Text_IO; +with Report; + +procedure CXAA005 is + An_Unbounded_File : Ada.Text_IO.File_Type; + Unbounded_File_Name : constant String := + Report.Legal_File_Name ( Nam => "CXAA005" ); + Incomplete : exception; + +begin + + Report.Test ("CXAA005", "Check that the procedure Put does not " & + "increment line numbers when used with " & + "unbounded text files of mode Append_File"); + + Test_for_Text_IO_Support: + begin + + -- An application creates a text file in mode Out_File, with the intention + -- of entering string data packets into the file as appropriate.
