* tst-initializers1.c: Show through exit code which test failed. * pthread_rwlock_init.c: Also initialize __shared field. * sysdeps/unix/sysv/linux/i386/bits/pthreadtypes.h: Split __flags element in rwlock structure into four byte elements. One of them is the new __shared element. * sysdeps/unix/sysv/linux/x86_64/bits/pthreadtypes.h [__WORDSIZE=32]: Likewise. [__WORDSIZE=64]: Renamed __pad1 element int rwlock structire to __shared, adjust names of other padding elements. * sysdeps/unix/sysv/linux/powerpc/bits/pthreadtypes.h: Likewise. * sysdeps/pthread/pthread.h: Adjust rwlock initializers. * sysdeps/unix/sysv/linux/lowlevelrwlock.sym: Add PSHARED. * sysdeps/unix/sysv/linux/powerpc/lowlevellock.h: Define FUTEX_PRIVATE_FLAG. * sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_rdlock.S: Change main futex to use private operations if possible. * sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_timedrdlock.S: Likewise. * sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_timedwrlock.S: Likewise. * sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_unlock.S: Likewise. * sysdeps/unix/sysv/linux/x86_64/pthread_rwlock_wrlock.S: Likewise.
