nptl: Remove futex_supports_exact_relative_timeouts
The only implementation of futex_supports_exact_relative_timeouts always
returns true. Let's remove it and all its callers.
* nptl/pthread_cond_wait.c: (__pthread_cond_clockwait): Remove code
that is only useful if futex_supports_exact_relative_timeouts ()
returns false.
* nptl/pthread_condattr_setclock.c: (pthread_condattr_setclock):
Likewise.
* sysdeps/nptl/futex-internal.h: Remove comment about relative
timeouts potentially being imprecise since it's no longer true.
Remove declaration of futex_supports_exact_relative_timeouts.
* sysdeps/unix/sysv/linux/futex-internal.h: Remove implementation
of futex_supports_exact_relative_timeouts.

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

nptl: Rename lll_timedlock to lll_clocklock and add clockid parameter
Rename lll_timedlock to lll_clocklock and add clockid
parameter to indicate the clock that the abstime parameter should
be measured against in preparation for adding
pthread_mutex_clocklock.
The name change mirrors the naming for the exposed pthread functions:
timed => absolute timeout measured against CLOCK_REALTIME (or clock
specified by attribute in the case of pthread_cond_timedwait.)
clock => absolute timeout measured against clock specified in preceding
parameter.
* sysdeps/nptl/lowlevellock.h (lll_clocklock): Rename from
lll_timedlock and add clockid parameter. (__lll_clocklock): Rename
from __lll_timedlock and add clockid parameter.
* sysdeps/unix/sysv/linux/sparc/lowlevellock.h (lll_clocklock):
Likewise.
* nptl/lll_timedlock_wait.c (__lll_clocklock_wait): Rename from
__lll_timedlock_wait and add clockid parameter. Use __clock_gettime
rather than __gettimeofday so that clockid can be used. This means
that conversion from struct timeval is no longer required.
* sysdeps/sparc/sparc32/lowlevellock.c (lll_clocklock_wait):
Likewise.
* sysdeps/sparc/sparc32/lll_timedlock_wait.c: Update comment to
refer to __lll_clocklock_wait rather than __lll_timedlock_wait.
* nptl/pthread_mutex_timedlock.c (lll_clocklock_elision): Rename
from lll_timedlock_elision, add clockid parameter and use
meaningful names for other parameters. (__pthread_mutex_timedlock):
Pass CLOCK_REALTIME where necessary to lll_clocklock and
lll_clocklock_elision.
* sysdeps/unix/sysv/linux/powerpc/lowlevellock.h
(lll_clocklock_elision): Rename from lll_timedlock_elision and add
clockid parameter. (__lll_clocklock_elision): Rename from
__lll_timedlock_elision and add clockid parameter.
* sysdeps/unix/sysv/linux/s390/lowlevellock.h: Likewise.
* sysdeps/unix/sysv/linux/x86/lowlevellock.h: Likewise.
* sysdeps/unix/sysv/linux/powerpc/elision-timed.c
(__lll_lock_elision): Call __lll_clocklock_elision rather than
__lll_timedlock_elision. (EXTRAARG): Add clockid parameter.
(LLL_LOCK): Likewise.

nptl: Add POSIX-proposed pthread_rwlock_clockrdlock & pthread_rwlock_clockwrlock
Add:
int pthread_rwlock_clockrdlock (pthread_rwlock_t *rwlock,
clockid_t clockid,
const struct timespec *abstime)
and:
int pthread_rwlock_clockwrlock (pthread_rwlock_t *rwlock,
clockid_t clockid,
const struct timespec *abstime)
which behave like pthread_rwlock_timedrdlock and
pthread_rwlock_timedwrlock respectively, except they always measure
abstime against the supplied clockid. The functions currently support
CLOCK_REALTIME and CLOCK_MONOTONIC and return EINVAL if any other
clock is specified.

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.

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.

nptl: pthread_rwlock: Move timeout validation into _full functions
As recommended by the comments in the implementations of
pthread_rwlock_timedrdlock and pthread_rwlock_timedwrlock, let's move
the timeout validity checks into the corresponding pthread_rwlock_rdlock_full
and pthread_rwlock_wrlock_full functions. Since these functions may be
called with abstime == NULL, an extra check for that is necessary too.
* nptl/pthread_rwlock_common.c (__pthread_rwlock_rdlock_full):
Check validity of abstime parameter.
(__pthread_rwlock_rwlock_full): Likewise.

* (pthread_rwlock_timedrdlock):
Remove check for validity of abstime parameter.

nptl: Add POSIX-proposed pthread_cond_clockwait
Add:
int pthread_cond_clockwait (pthread_cond_t *cond,
pthread_mutex_t *mutex,
clockid_t clockid,
const struct timespec *abstime)
which behaves just like pthread_cond_timedwait except it always measures
abstime against the supplied clockid. Currently supports CLOCK_REALTIME
and
CLOCK_MONOTONIC and returns EINVAL if any other clock is specified.
Includes feedback from many others. This function was originally
proposed[1] as pthread_cond_timedwaitonclock_np, but The Austin Group
preferred the new name.

from
the flags. (__pthread_cond_wait): Pass unused clockid parameter.

Add:
int sem_clockwait (sem_t *sem, clockid_t clock, const struct timespec

nptl: Add clockid parameter to futex timed wait calls
In preparation for adding POSIX clockwait variants of timedwait functions,
add a clockid_t parameter to futex_abstimed_wait functions and pass
CLOCK_REALTIME from all callers for the time being.
Replace lll_futex_timed_wait_bitset with lll_futex_clock_wait_bitset
which takes a clockid_t parameter rather than the magic clockbit.
* sysdeps/nptl/lowlevellock-futex.h,
sysdeps/unix/sysv/linux/lowlevellock-futex.h: Replace
lll_futex_timed_wait_bitset with lll_futex_clock_wait_bitset that
takes a clockid rather than a special clockbit.
* sysdeps/nptl/lowlevellock-futex.h: Add
lll_futex_supported_clockid so that client functions can check
whether their clockid parameter is valid even if they don't
ultimately end up calling lll_futex_clock_wait_bitset.
* sysdeps/nptl/futex-internal.h,
sysdeps/unix/sysv/linux/futex-internal.h
(futex_abstimed_wait, futex_abstimed_wait_cancelable): Add
clockid_t parameter to indicate which clock the absolute time
passed should be measured against. Pass that clockid onto
lll_futex_clock_wait_bitset. Add invalid clock as reason for
returning -EINVAL.
* sysdeps/nptl/futex-internal.h,
sysdeps/unix/sysv/linux/futex-internal.h: Introduce
futex_abstimed_supported_clockid so that client functions can check
whether their clockid parameter is valid even if they don't
ultimately end up calling futex_abstimed_wait.
* nptl/pthread_cond_wait.c (__pthread_cond_wait_common): Remove
code to calculate relative timeout for
__PTHREAD_COND_CLOCK_MONOTONIC_MASK and just pass CLOCK_MONOTONIC

(__pthread_wrlock_full), nptl/sem_waitcommon (do_futex_wait): Pass

nptl: Add POSIX-proposed sem_clockwait
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: Add clockid parameter to futex timed wait calls
In preparation for adding POSIX clockwait variants of timedwait functions,
add a clockid_t parameter to futex_abstimed_wait functions and pass
CLOCK_REALTIME from all callers for the time being.
Replace lll_futex_timed_wait_bitset with lll_futex_clock_wait_bitset
which takes a clockid_t parameter rather than the magic clockbit.
* sysdeps/nptl/lowlevellock-futex.h,
sysdeps/unix/sysv/linux/lowlevellock-futex.h: Replace
lll_futex_timed_wait_bitset with lll_futex_clock_wait_bitset that
takes a clockid rather than a special clockbit.
* sysdeps/nptl/lowlevellock-futex.h: Add
lll_futex_supported_clockid so that client functions can check
whether their clockid parameter is valid even if they don't
ultimately end up calling lll_futex_clock_wait_bitset.
* sysdeps/nptl/futex-internal.h,
sysdeps/unix/sysv/linux/futex-internal.h
(futex_abstimed_wait, futex_abstimed_wait_cancelable): Add
clockid_t parameter to indicate which clock the absolute time
passed should be measured against. Pass that clockid onto
lll_futex_clock_wait_bitset. Add invalid clock as reason for
returning -EINVAL.
* sysdeps/nptl/futex-internal.h,
sysdeps/unix/sysv/linux/futex-internal.h: Introduce
futex_abstimed_supported_clockid so that client functions can check
whether their clockid parameter is valid even if they don't
ultimately end up calling futex_abstimed_wait.
* nptl/pthread_cond_wait.c (__pthread_cond_wait_common): Remove
code to calculate relative timeout for
__PTHREAD_COND_CLOCK_MONOTONIC_MASK and just pass CLOCK_MONOTONIC
or CLOCK_REALTIME as required to futex_abstimed_wait_cancelable.
* nptl/pthread_rwlock_common (__pthread_rwlock_rdlock_full)
(__pthread_wrlock_full), nptl/sem_waitcommon (do_futex_wait): Pass
additional CLOCK_REALTIME to futex_abstimed_wait_cancelable.
* nptl/pthread_mutex_timedlock.c (__pthread_mutex_timedlock):
Switch to lll_futex_clock_wait_bitset and pass CLOCK_REALTIME
