Initialize __libc_locking_needed. * init.c (__pthread_initialize_minimal): Call __libc_pthread_init instead of __register_pthread_fork_handler. * sysdeps/pthread/bits/libc-lock.h: Declare __libc_locking_needed. * sysdeps/unix/sysv/linux/Makefile (sysdep_routimes): Replace fork-gen with libc_pthread_init. * sysdeps/unix/sysv/linux/Versions: Use __libc_pthread_init instead of __register_pthread_fork_handler. * sysdeps/unix/sysv/linux/fork.h: Declare __libc_pthread_init instead of __register_pthread_fork_handler. * sysdeps/unix/sysv/linux/i386/lowlevellock.h: Use __libc_locking_needed to determine whether lock prefix can be avoided. * sysdeps/unix/sysv/linux/i386/i486/libc-lowlevellock.S: Likewise. --- nptl/sysdeps/pthread/bits/libc-lock.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'nptl/sysdeps/pthread/bits/libc-lock.h') diff --git a/nptl/sysdeps/pthread/bits/libc-lock.h b/nptl/sysdeps/pthread/bits/libc-lock.h index de2ec7bb25..e594ede1dd 100644 --- a/nptl/sysdeps/pthread/bits/libc-lock.h +++ b/nptl/sysdeps/pthread/bits/libc-lock.h @@ -25,6 +25,10 @@ #include +/* Nonzero if locking is needed. */ +extern int __libc_locking_needed attribute_hidden; + + /* Fortunately Linux now has a mean to do locking which is realtime safe without the aid of the thread library.
