Add: int sem_clockwait (sem_t *sem, clockid_t clock, const struct timespec *abstime) which behaves just like sem_timedwait, but measures abstime against the specified clock. Currently supports CLOCK_REALTIME and CLOCK_MONOTONIC and sets errno == EINVAL if any other clock is specified. * nptl/sem_waitcommon.c (do_futex_wait, __new_sem_wait_slow): Add clockid parameters to indicate the clock which abstime should be measured against. * nptl/sem_timedwait.c (sem_timedwait), nptl/sem_wait.c (__new_sem_wait): Pass CLOCK_REALTIME as clockid to __new_sem_wait_slow. * nptl/sem_clockwait.c: New file to implement sem_clockwait based on sem_timedwait.c. * nptl/Makefile: Add sem_clockwait.c source file. Add CFLAGS for sem_clockwait.c to match those used for sem_timedwait.c. * sysdeps/pthread/semaphore.h: Add sem_clockwait. * nptl/Versions (GLIBC_2.30): Likewise. * 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-sem17.c: Add new test for passing invalid clock to sem_clockwait. * nptl/tst-sem13.c, nptl/tst-sem5.c: Modify existing sem_timedwait tests to also test sem_clockwait. * manual/threads.texi: Document sem_clockwait.
