* Improve random memcpy benchmarkWilco Dijkstra2020-02-101-29/+57
| | | | | | | | | Improve the random memcpy benchmark. Double the number of copies and increase the memory sizes tested to 512KB. Add a more detailed distribution of memcpy alignment and sizes up to 4096 based on SPEC2017 traces. Reviewed-by: Siddhesh Poyarekar <siddhesh@sourceware.org>
* nptl: update default pthread-offsets.hAndreas Schwab2020-02-101-16/+6
| | | | | Remove unused definitions, and correct __PTHREAD_RWLOCK_FLAGS_OFFSET for __WORDSIZE == 64.
* nptl: add missing pthread-offsets.hAndreas Schwab2020-02-105-0/+25
| | | | | All architectures using their own definition of struct __pthread_rwlock_arch_t need to provide their own pthread-offsets.h.

|
* pthread: Move some join tests from nptl to sysdeps/pthreadSamuel Thibault2020-02-1014-13/+16
| | | | So they can be checked with htl too.

|
* htl: Make sem_open return ENOSYSSamuel Thibault2020-02-101-1/+1
| | | | instead of EOPNOTSUPP, which is for sockets.
* htl: Add support for semaphore maximum valueSamuel Thibault2020-02-102-0/+10

* pthread: Move key tests from nptl to sysdeps/pthreadSamuel Thibault2020-02-106-1/+1

* htl: XFAIL rwlock tests which need pshared supportSamuel Thibault2020-02-091-0/+2
|
* pthread: Move some rwlock tests from nptl to sysdeps/pthreadSamuel Thibault2020-02-099-5/+6
| | | | So they can be checked with htl too.
* pthread: Move most once tests from nptl to sysdeps/pthreadSamuel Thibault2020-02-098-5/+8
| | | | So they can be checked with htl too.

* htl: Report missing mutex lock on pthread_cond_*waitSamuel Thibault2020-02-094-1/+59
|
* htl: Fix linking static testcasesSamuel Thibault2020-02-091-0/+2
| | | | They need libpthread.a
* htl: Move __register_atfork from forward to own fileSamuel Thibault2020-02-093-139/+158
| | | | Since we need it also in the static linking case.
* pthread: Move some attr tests from nptl to sysdeps/pthreadSamuel Thibault2020-02-093-1/+2
| | | | So they can be checked with htl too.
* htl: Fix default guard sizeSamuel Thibault2020-02-093-2/+6
| | | | | When it is not hardcoded by the architecture with PAGESIZE, we need to use the dynamic values from __vm_page_size.
* pthread: Move most mutex tests from nptl to sysdeps/pthreadSamuel Thibault2020-02-0910-3/+8
| | | | | | So they can be checked with htl too. XFAIL tst-mutex4, for which support is still missing in htl.
* pthread: Move spin tests from nptl to sysdeps/pthreadSamuel Thibault2020-02-096-1/+1
| | | | So they can be checked with htl too.
* htl: make pthread_spin_lock really spinSamuel Thibault2020-02-091-1/+1
| | | | | __spin_lock would actually use gsync_wait to block, which is not what pthread_spin_lock is about.
* htl: Avoid check-installed-headers looking at inlinesSamuel Thibault2020-02-091-2/+4
|
* htl: Do not put spin_lock inlines in public headersSamuel Thibault2020-02-092-36/+36
| | | | | | They were not getting used anyway. Also do not make libsupport use them, it would make tests using it have to be made to link against libmachuser for gsync_wait.
* pthread: Move basic tests from nptl to sysdeps/pthreadSamuel Thibault2020-02-099-3/+8
| | | | So they can be checked with htl too.
* htl: Fix calling pthread_exit in the child of a forkSamuel Thibault2020-02-091-0/+9
| | | | | We need to reset the threads counter, otherwise pthread_exit() would not call exit(0).
* x86: Remove <bits/select.h> and use the generic versionFlorian Weimer2020-02-091-63/+0
| | | | | | Particularly on CPUs without ERMS, the string instructions are slow, so it is unclear whether this architecture-specific implementation is in fact an optimization.
* C11 threads: Move implementation to sysdeps/pthreadSamuel Thibault2020-02-0949-77/+127
| | | | | | | so it gets shared by nptl and htl. Also add htl versions of thrd_current and thrd_yield. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

* C11 threads: make thrd_join more portableSamuel Thibault2020-02-091-1/+1

* htl: Make __PTHREAD_ONCE_INIT more flexibleSamuel Thibault2020-02-092-2/+2

* htl: Move internal mutex/rwlock symbols to GLIBC_PRIVATESamuel Thibault2020-02-092-11/+4
| | | | | Their prototypes have never been made public, and they are not used outside libc (checked on the whole Debian archive)
* Linux: Add io/tst-o_path-locks testFlorian Weimer2020-02-092-1/+101
| | | | | | The O_PATH-based fchmodat emulation will rely on the fact that closing an O_PATH descriptor never releases POSIX advisory locks, so this commit adds a test case for this behavior.
