* stdio.h: Don't define unlocked macros using static inline on C++cygwin-2_9_0-releaseCorinna Vinschen2017-09-041-1/+1
| | | | | | | | | | | | In C++, the usage of static inline functions for getchar_unlocked and putchar_unlocked may result in error messages like error: ‘_putchar_unlocked’ was not declared in this scope Fix this by not using the _getchar_unlocked and _putchar_unlocked macros in C++.

* Revert "headers: avoid bareword attributes" for clangEric Blake2017-08-251-14/+16
| | | | | | | | | | | | | | | This reverts most of commit 979d467ff6e39ee5c52cf1aac7a6c9c63058141c. We cannot avoid some bareword attributes until clang is fixed to properly support __-decorated attributes; see this bug: https://bugs.llvm.org/show_bug.cgi?id=34319 The macros in question expand to the empty string under gcc, so only compilation under clang is affected, and since clang has the bug, the obvious solution is to roll back the changes, and document the issue.

| | | | | | | | | | | | | Add internal inline functions _getchar_unlocked() and _putchar_unlocked() if __CUSTOM_FILE_IO__ is not defined. These functions get _REENT only once. Use them for getchar_unlocked() and putchar_unlocked().

* Introduce _REENT_GLOBAL_STDIO_STREAMSSebastian Huber2017-06-301-6/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* 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.

This change is backwards compatible for all use within C and C++ programs. Only C++ programs will have added support to use the queue macros within classes.

* don't use C99 static array indices with older GCC versionsavg2017-04-041-0/+1
| | | | | | | | | | | | | | For example, the FreeBSD GCC (4.2.1) has a spotty support for that feature. If the static keyword is used with an unnamed array parameter in a function declaration, then the compilation fails with: error: static or type qualifiers in abstract declarator The feature does work if the parameter is named. So, the restriction introduced in this commit can be removed when all affected function prototypes have the workaround. MFC after: 1 week Sponsored by: Panzura

Add two new macros: __NULLABILITY_PRAGMA_PUSH __NULLABILITY_PRAGMA_POP These are for use in headers when we want avoid noisy warnings if some pointers are left without nullability annotations. These are added with way ahead of their first use to teach the GCC ports headers of their existance before their first use.

* Addition of clang nullability qualifiers.pfg2017-04-041-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Add two new qualifiers for use by the static checkers: _Nonnull The _Nonnull nullability qualifier indicates that null is not a meaningful value for a value of the _Nonnull pointer type. _Nullable The _Nullable nullability qualifier indicates that a value of the _Nullable pointer type can be null. These were introduced in Clang 3.7. For more information, see: http://clang.llvm.org/docs/AttributeReference.html#nonnull We add these now without using them so that the GCC ports have time to pick up the header change.

* Fix C++ includability of crypto headers with static array sizesasomers2017-04-041-0/+14
| | | | | | | | | | | | | | | | | | | | | | C99 allows array function parameters to use the static keyword for their sizes. This tells the compiler that the parameter will have at least the specified size, and calling code will fail to compile if that guarantee is not met. However, this syntax is not legal in C++. This commit reverts r300824, which worked around the problem for sys/md5.h only, and introduces a new macro: min_size(). min_size(x) can be used in headers as a static array size, but will still compile in C++ mode.
