nptl: Add POSIX-proposed pthread_mutex_clocklock
Add POSIX-proposed pthread_mutex_clocklock function that works like pthread_mutex_timedlock but takes a clockid parameter to measure the abstime parameter against. * sysdeps/nptl/pthread.h: Add pthread_mutex_clocklock. * nptl/DESIGN-systemtap-probes.txt: Likewise. * nptl/pthread_mutex_timedlock.c (__pthread_mutex_clocklock_common): Rename from __pthread_mutex_timedlock and add clockid parameter. Pass this parameter to lll_clocklock and lll_clocklock_elision in place of CLOCK_REALTIME. (__pthread_mutex_clocklock): New function to add LIBC_PROBE and validate clockid parameter before calling __pthread_mutex_clocklock_common. (__pthread_mutex_timedlock): New implementation to add LIBC_PROBE and calls __pthread_mutex_clocklock_common passing CLOCK_REALTIME as the clockid. * nptl/Makefile: Add tst-mutex11.c. * nptl/tst-abstime.c (th): Add tests for pthread_mutex_clocklock. * nptl/tst-mutex11.c: New tests for passing invalid and unsupported clockid parameters to pthread_mutex_clocklock. * nptl/tst-mutex5.c (do_test_clock): Rename from do_test and take clockid parameter to indicate which clock to be used. Call pthread_mutex_timedlock or pthread_mutex_clocklock as appropriate. (do_test): Call do_test_clock to separately test pthread_mutex_timedlock, pthread_mutex_clocklock(CLOCK_REALTIME) and pthread_mutex_clocklock(CLOCK_MONOTONIC). * nptl/tst-mutex9.c: Likewise. * nptl/Versions (GLIBC_2.30): Add pthread_mutex_clocklock. * 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.
