From 6b4686a534c10cc9011c9d352d1b57d5a76d5579 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 2 Apr 2003 03:51:24 +0000 Subject: Update. 2003-04-01 Ulrich Drepper * pthread_create.c (deallocate_tsd): Clear/free memory after the last round, not the first. Use specific_used flag instead of local found_nonzero variable. Use THREAD_[SG]ETMEM where possible. (__free_tcb): Don't call deallocate_tsd here. (start_thread): Call deallocate_tsd here. * pthread_setspecific.c: Set specific_used flag really only when needed. * Makefile (tests): Add tst-tsd3.c * tst-tsd3.c: New file. --- nptl/tst-tsd3.c | 129 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 129 insertions(+) create mode 100644 nptl/tst-tsd3.c (limited to 'nptl/tst-tsd3.c') diff --git a/nptl/tst-tsd3.c b/nptl/tst-tsd3.c new file mode 100644 index 0000000000..6cdf749914 --- /dev/null +++ b/nptl/tst-tsd3.c @@ -0,0 +1,129 @@ +/* Copyright (C) 2003 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Ulrich Drepper , 2003. + + 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.
