| | | | | | | | | | | Include <strings.h> in <string.h> if __BSD_VISIBLE like on FreeBSD. Remove redundant declarations from <string.h>. Make ffsl(), ffsll(), strncasecmp(), strcasecmp_l(), and strncasecmp_l() visible via __BSD_VISIBLE instead of __GNU_VISIBLE. Add fls(), flsl(), and flsll() to <strings.h> if __BSD_VISIBLE.

* | Introduce _REENT_GLOBAL_STDIO_STREAMS | Sebastian Huber | 2017-06-30 | 2 | -6/+39 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Newlib, the stdio streams are defined to thread-specific pointers _reent::_stdin, _reent::_stdout and _reent::_stderr. In case _REENT_SMALL is not defined, then these pointers are initialized via _REENT_INIT_PTR() or _REENT_INIT_PTR_ZEROED() to thread-specific FILE objects provided via _reent::__sf[3]. There are two problems with this (at least in case of RTEMS). (1) The thread-specific FILE objects are closed by _reclaim_reent(). This leads to problems with language run-time libraries that provide wrappers to the C/POSIX stdio streams (e.g. C++ and Ada), since they use the thread-specific FILE objects of the initialization thread. In case the initialization thread is deleted, then they use freed memory. (2) Since thread-specific FILE objects are used with a common output device via file descriptors 0, 1 and 2, the locking at FILE object level cannot ensure atomicity of the output, e.g. a call to printf(). Introduce a new Newlib configuration option _REENT_GLOBAL_STDIO_STREAMS to enable the use of global stdio FILE objects. As a side-effect this reduces the size of struct _reent by more than 50%. The _REENT_GLOBAL_STDIO_STREAMS should not be used without _STDIO_CLOSE_PER_REENT_STD_STREAMS. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de> | ||||

* | Optimized memcmp | Wilco Dijkstra | 2017-06-29 | 1 | -193/+113 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an optimized memcmp for AArch64. This is a complete rewrite using a different algorithm. The previous version split into cases where both inputs were aligned, the inputs were mutually aligned and unaligned using a byte loop. The new version combines all these cases, while small inputs of less than 8 bytes are handled separately. This allows the main code to be sped up using unaligned loads since there are now at least 8 bytes to be compared. After the first 8 bytes, align the first input. This ensures each iteration does at most one unaligned access and mutually aligned inputs behave as aligned. After the main loop, process the last 8 bytes using unaligned accesses. This improves performance of (mutually) aligned cases by 25% and unaligned by >500% (yes >6 times faster) on large inputs.

That change has been submitted for review to Bionic libc: https://android-review.googlesource.com/418279 A similar patch has been submitted for review in glibc: https://sourceware.org/ml/libc-alpha/2017-06/msg01143.html Patch written by Vikas Sinha and Sebastian Pop. The performance was measured on the bionic-benchmarks on a hikey (aarch64 8xA53) board. There was no performance change to the existing benchmark and a performance improvement on the new benchmark for memcmp on the unaligned side. The new benchmark has been submitted for review at https://android-review.googlesource.com/414860 The overall performance improves by 18% for the small data set 8 and the performance improves by 450% for the large data set 64k. The base is with the libc from /system/lib64.

* | Fix guard for siginfo_t and pthread_t definition | Thomas Preud'homme | 2017-06-19 | 2 | -8/+12 |
| | | | | | | | | | | | | | Commit 8a3b3bb4d7224d419cc1a4af60ccf7e70edc876b changed the guard on some functions from _POSIX_THREADS to __POSIX_VISIBLE. As a consequence, some use of siginfo_t and pthread_t became visible under configurations where _POSIX_THREADS is unset but __POSIX_VISIBLE is. Build then fails because the definition of those types are still unavailable. This commit make those type definition visible for __POSIX_VISIBLE configurations. This requires moving the siginfo_t definition out of the RTEMS specific definitions in sys/signal.h while still guarding it against cygwin case. | ||||

* | Export XSI sigpause | Yaakov Selkowitz | 2017-06-14 | 1 | -1/+13 |
| | | | | | | | | | | There are two common sigpause variants, both of which take an int argument. If you request _XOPEN_SOURCE or _GNU_SOURCE, you get the System V version, which removes the given signal from the process's signal mask; otherwise you get the BSD version, which sets the process's signal mask to the given value.
