From d15851ec24d31ccf3ee9a4a388104974d1f494dc Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sat, 22 Mar 2003 23:01:01 +0000 Subject: * include/atomic.h (atomic_increment_and_test): Invert sense of test. Add comment. (atomic_decrement_and_test): Add comment. 2003-03-22 Jakub Jelinek * include/atomic.h (atomic_compare_and_exchange_val_acq): Add comment. Don't define if __arch_compare_and_exchange_val_32_acq is not defined. (atomic_compare_and_exchange_bool_acq): Add comment. Don't use __oldval variable in the macro, since it might be macro argument. (atomic_decrement_if_positive): Initialize __memp, remove setting of non-existent variable. (atomic_bit_test_set): Cast 1 to __typeof (*mem) before shifting. * sysdeps/ia64/bits/atomic.h (atomic_exchange_and_add): Implement using atomic_compare_and_exchange_val_acq. (atomic_decrement_if_positive, atomic_bit_test_set): Define. * sysdeps/s390/bits/atomic.h (__arch_compare_and_exchange_val_8_acq): Renamed from... (__arch_compare_and_exchange_bool_8_acq): ... this. (__arch_compare_and_exchange_val_16_acq): Renamed from... (__arch_compare_and_exchange_bool_16_acq): ... this. (__arch_compare_and_exchange_val_32_acq): Return old value. Renamed from... (__arch_compare_and_exchange_bool_32_acq): ... this. (__arch_compare_and_exchange_val_64_acq): Return old value. Renamed from... (__arch_compare_and_exchange_bool_64_acq): ... this. (__arch_compare_and_exchange_val_32_acq): Use __typeof for local variables types instead of assuming int. Change prefix of local variables to __arch. * sysdeps/generic/bits/atomic.h (arch_compare_and_exchange_acq): Remove. (atomic_compare_and_exchange_val_acq, atomic_compare_and_exchange_bool_acq): Define. * csu/tst-atomic.c: New test. * csu/tst-atomic-long.c: New test. * csu/Makefile (tests): Add tst-atomic and tst-atomic-long. * malloc/memusagestat.c (main): Kill warning if uint64_t is ulong. * sysdeps/s390/Versions: Add trailing newline. * sysdeps/unix/sysv/linux/sysconf.c (__sysconf): Kill warning if INTERNAL_SYSCALL_ERROR_P doesn't use its first argument. --- csu/tst-atomic-long.c | 28 ++++++++++++++++++++++++++++ 1 file changed, 28 insertions(+) create mode 100644 csu/tst-atomic-long.c (limited to 'csu/tst-atomic-long.c') diff --git a/csu/tst-atomic-long.c b/csu/tst-atomic-long.c new file mode 100644 index 0000000000..75a71ebd5f --- /dev/null +++ b/csu/tst-atomic-long.c @@ -0,0 +1,28 @@ +/* Tests for atomic.h macros. + Copyright (C) 2003 Free Software Foundation, Inc. + This file is part of the GNU C Library. + Contributed by Jakub Jelinek , 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.
