* Fix mq_notify pthread_barrier_* namespace (bug 18544).Joseph Myers2015-06-171-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mq_notify (present in POSIX by 1996) brings in references to pthread_barrier_init and pthread_barrier_wait (new in the 2001 edition of POSIX). This patch fixes this by making those functions into weak aliases of __pthread_barrier_*, exporting the __pthread_barrier_* names at version GLIBC_PRIVATE and using them in mq_notify. Tested for x86_64 and x86 (testsuite, and comparison of installed stripped shared libraries). Changes in addresses from dynamic symbol table / PLT changes render most comparisons not particularly useful, but when the addresses of subsequent code don't change there's no sign of unexpected changes there. This patch does not remove any linknamespace XFAILs because of other namespace issues remaining with mqueue.h functions. [BZ #18544] * nptl/pthread_barrier_init.c (pthread_barrier_init): Rename to __pthread_barrier_init and define as weak alias of __pthread_barrier_init. * sysdeps/sparc/nptl/pthread_barrier_init.c (pthread_barrier_init): Likewise. * nptl/pthread_barrier_wait.c (pthread_barrier_wait): Rename to __pthread_barrier_wait and define as weak alias of __pthread_barrier_wait. * sysdeps/sparc/nptl/pthread_barrier_wait.c (pthread_barrier_wait): Likewise. * sysdeps/sparc/sparc32/pthread_barrier_wait.c (pthread_barrier_wait): Likewise. * sysdeps/unix/sysv/linux/i386/i486/pthread_barrier_wait.S (pthread_barrier_wait): Likewise. * sysdeps/unix/sysv/linux/x86_64/pthread_barrier_wait.S (pthread_barrier_wait): Likewise. * nptl/Versions (libpthread): Export __pthread_barrier_init and __pthread_barrier_wait at version GLIBC_PRIVATE. * include/pthread.h (__pthread_barrier_init): Declare. (__pthread_barrier_wait): Likewise. * sysdeps/unix/sysv/linux/mq_notify.c (notification_function): Call __pthread_barrier_wait instead of pthread_barrier_wait. (helper_thread): Likewise. (init_mq_netlink): Call __pthread_barrier_init instead of pthread_barrier_init.

Fix typo p_type -> p_vaddr. * include/pthread.h: Don't declare __pthread_initialize_minimal as weak here; we declare it weak or strong in the one place we use it. * sysdeps/generic/libc-start.c: ... which is here. Don't make the decl weak if [USE_TLS], since static programs need TLS setup even when single-threaded.
