Add comment. (atomic_decrement_and_test): Add comment. 2003-03-22 Jakub Jelinek <jakub@redhat.com> * 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.
