* aarch64: optimize the unaligned case of memcmpSebastian Pop2017-06-261-2/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This brings to newlib a performance improvement that we developed in Bionic libc. 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 definitionThomas Preud'homme2017-06-192-8/+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 sigpauseYaakov Selkowitz2017-06-141-1/+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.

* stdio.h: guard function macros with !__cplusplusYaakov Selkowitz2017-06-141-0/+2
| | | | | | | | While POSIX allows these functions to also be defined as macros in C, in C++ this is not allowed, and prevents these names (particularly feof) from being used in a custom namespace. Signed-off-by: Yaakov Selkowitz <yselkowi@redhat.com>

* Remove FreeBSD specifics from RTEMS <arpa/inet.h>Sebastian Huber2017-06-121-21/+0
| | | | | | | | | For whatever reason FreeBSD renames several functions provided by <arpa/inet.h> and uses weak references to provide the standard function names. This causes problems on targets lacking proper support for weak references. We do not need this function renaming on RTEMS. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* Don't overread or write memory returned by _DTOA_RSilviu Baranga2017-06-091-12/+13
| | | | | | | | | | | | | | | Don't over-read memory returned by _DTOA_R, and never write to it since the result might be a string literal. For example, when doing: swprintf(tt, 20, L"%.*f", 6, 0.0); we will get back "0". Instead, write the result returned by _DTOA_R to the output buffer. After this, write the 0 chars directly to the the output buffer (if there are any). This also has the (marginal) advantage that we read/write less memory overall.

| | | | | | | | | The implementation of the POSIX access() function is nothing machine specific like memcpy(), etc. Move it back to the system domain.

* newlib: remove __infinity{f,ld} constantsCorinna Vinschen2017-04-185-35/+6
| | | | | | | | | | | | | | | previous commit 4c90db7bc89e7fa1077025fefdd58269dc71a6ac introduced a compile time error because libm/common/s_infconst.c used the remove __fmath, __dmath, and __ldmath union types. Since this is very old, and unused for a very long time, just drop the file and thus the __infinity constants entirely. Exception: Cygwin exports __infinity from the beginning. There's a very, VERY low probability that any existing executable or lib still uses this constant, but we just keep it in for backward compat, nevertheless.
