From 99ef2719fb3d703fe38c4113cd7f5adec516dd3a Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Fri, 28 Oct 2016 20:29:21 +0200 Subject: test: remove test suite The test suite is now a developed in a separate git repository. See here: http://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng-test.git The test suite should be just like every other software compiled with the cross-toolchain. In the past strange problems where found when the test suite got build in the toolchain creation step. --- test/nptl/tst-cpuclock1.c | 306 ---------------------------------------------- 1 file changed, 306 deletions(-) delete mode 100644 test/nptl/tst-cpuclock1.c (limited to 'test/nptl/tst-cpuclock1.c') diff --git a/test/nptl/tst-cpuclock1.c b/test/nptl/tst-cpuclock1.c deleted file mode 100644 index 9d68ec520..000000000 --- a/test/nptl/tst-cpuclock1.c +++ /dev/null @@ -1,306 +0,0 @@ -/* Test program for process CPU clocks. - Copyright (C) 2004 Free Software Foundation, Inc. - This file is part of the GNU C Library. - - The GNU C Library is free software; you can redistribute it and/or - modify it under the terms of the GNU Lesser General Public - License as published by the Free Software Foundation; either - version 2.1 of the License, or (at your option) any later version. - - The GNU C Library is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
