From 09402f5bc1d87787c84dbf75d41777c87b1ce40e Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 25 Mar 2003 20:41:26 +0000 Subject: Update. 2003-03-25 Ulrich Drepper * csu/tst-atomic.c: Adjust tests to what atomic_add_negative and atomic_add_zero were supposed to do. * include/atomic.h: Adjust atomic_add_negative and atomic_add_zero to x86 behavior. * sysdeps/generic/bits/typesizes.h (__TIMER_T_TYPE): Define as void*. This matches the new timer implementation. * sysdeps/unix/sysv/linux/bits/siginfo.h (struct siginfo): Adjust timer info for what the kernel provides these days. (struct sigevent): Add _tid field. Define SIGEV_THREAD_ID. * Versions.def (librt): Add GLIBC_2.3.3. * abilist/libpthread.abilist: Update for nptl. --- nptl/init.c | 10 ++++++++++ 1 file changed, 10 insertions(+) (limited to 'nptl/init.c') diff --git a/nptl/init.c b/nptl/init.c index 4237c6eb48..2c85d87b99 100644 --- a/nptl/init.c +++ b/nptl/init.c @@ -225,6 +225,16 @@ __pthread_initialize_minimal_internal (void) NULL, _NSIG / 8); + /* The kernel supported POSIX timer handling needs a signal to implement + SIGEV_THREAD.
