The functions currently support CLOCK_REALTIME + and CLOCK_MONOTONIC and return EINVAL if any other clock is + specified. + * sysdeps/nptl/pthread.h: Add pthread_rwlock_clockrdlock and + pthread_wrlock_clockwrlock. + * nptl/Makefile: Build pthread_rwlock_clockrdlock.c and + pthread_rwlock_clockwrlock.c. + * nptl/pthread_rwlock_clockrdlock.c: Implement + pthread_rwlock_clockrdlock. + * nptl/pthread_rwlock_clockwrlock.c: Implement + pthread_rwlock_clockwrlock. + * nptl/pthread_rwlock_common.c (__pthread_rwlock_rdlock_full): Add + clockid parameter and verify that it indicates a supported clock on + entry so that we fail even if it doesn't end up being used. Pass + that clock on to futex_abstimed_wait when necessary. + (__pthread_rwlock_wrlock_full): Likewise. + * nptl/pthread_rwlock_rdlock.c: (__pthread_rwlock_rdlock): Pass + CLOCK_REALTIME to __pthread_rwlock_rdlock_full even though it won't + be used because there's no timeout. + * nptl/pthread_rwlock_wrlock.c (__pthread_rwlock_wrlock): Pass + CLOCK_REALTIME to __pthread_rwlock_wrlock_full even though it won't + be used because there is no timeout. + * nptl/pthread_rwlock_timedrdlock.c (pthread_rwlock_timedrdlock): + Pass CLOCK_REALTIME to __pthread_rwlock_rdlock_full since abstime + uses that clock. + * nptl/pthread_rwlock_timedwrlock.c (pthread_rwlock_timedwrlock): + Pass CLOCK_REALTIME to __pthread_rwlock_wrlock_full since abstime + uses that clock. + * sysdeps/unix/sysv/linux/aarch64/libpthread.abilist (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/alpha/libpthread.abilist (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/arm/libpthread.abilist (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/csky/libpthread.abilist (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/hppa/libpthread.abilist (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/i386/libpthread.abilist (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/ia64/libpthread.abilist (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/m68k/coldfire/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/m68k/m680x0/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/microblaze/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/mips/mips32/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/mips/mips64/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/nios2/libpthread.abilist (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/powerpc/powerpc32/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/powerpc/powerpc64/be/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/powerpc/powerpc64/le/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/riscv/rv64/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/s390/s390-32/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/s390/s390-64/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/sh/libpthread.abilist (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/sparc/sparc32/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/sparc/sparc64/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/x86_64/64/libpthread.abilist + (GLIBC_2.30): Likewise. + * sysdeps/unix/sysv/linux/x86_64/x32/libpthread.abilist + (GLIBC_2.30): Likewise. + * nptl/tst-abstime.c (th): Add pthread_rwlock_clockrdlock and + pthread_rwlock_clockwrlock timeout tests to match the existing + pthread_rwlock_timedrdloock and pthread_rwlock_timedwrlock tests. + * nptl/tst-rwlock14.c (do_test): Likewise. + * nptl/tst-rwlock6.c Invent verbose_printf macro, and use for + ancillary output throughout.
