* Rename <sys/_locale.h> to <xlocale.h>Yaakov Selkowitz2017-03-2210-12/+12
| | | | | | | | | The locale_t type is provided by <xlocale.h> on Linux, FreeBSD, and Darwin. While, like on some of those systems, it is automatically included by <locale.h> with the proper feature test macros, its presence under this particular name is still presumed in real-world software.

* Allow locking routine to be retargetedThomas Preud'homme2017-02-131-2/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment when targeting bare-metal targets or systems without definition for the locking primitives newlib, uses dummy empty macros. This has the advantage of reduced size and faster implementation but does not allow the application to retarget the locking routines. Retargeting is useful for a single toolchain to support multiple systems since then it's only at link time that you know which system you are targeting. This patch adds a new configure option --enable-newlib-retargetable-locking to use dummy empty functions instead of dummy empty macros. The default is to keep the current behavior to not have any size or speed impact on targets not interested in this feature. To allow for any size of lock, the _LOCK_T type is changed into pointer to struct _lock and the _init function are tasked with allocating the locks. The platform being targeted must provide the static locks. A dummy implementation of the locking routines and static lock is provided for single-threaded applications to link successfully out of the box. To ensure that the behavior is consistent (either no locking whatsoever or working locking), the dummy implementation is strongly defined such that a partial retargeting will cause a doubly defined link error. Indeed, the linker will only pull in the file providing the dummy implementation if it cannot find an implementation for one of the routine or lock.
* devctl.h: Fix typo and include proper headerSebastian Huber2017-01-251-6/+6
| | | | | | | Remove stray commas. Include <sys/cdefs.h> for __restrict (includes <stddef.h> indirectly). Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* nl_langinfo: Add NL_LOCALE_NAME macroEric Blake2017-01-201-1/+9
| | | | | | | | | | | | | | | | | | | | | Provide an extension NL_LOCALE_NAME() macro, with semantics matching glibc, which can be used as: nl_langinfo_l(NL_LOCALE_NAME(LC_MESSAGES), locale); to get back the locale string that locale was originally created with during newlocale(). This in turn allows a library (such as gettext) to determine what thread-local locale settings it has inherited from the main program without having to be told what parameters were passed to newlocale(), for less overall coupling between parts of the program. gnulib is set up to use the extension: https://lists.gnu.org/archive/html/bug-gnulib/2017-01/msg00129.html * libc/include/langinfo.h (NL_LOCALE_NAME): New macro * libc/locale/nl_langinfo.c (nl_langinfo_l): Expose locale names of a locale_t's category components.

* Fix sys/reent.h to remove use of DEBUG flag.Jeff Johnston2017-01-101-2/+2
| | | | | | | | - use of DEBUG flag is non-standard and interferes with other project's using same flag - change to be _REENT_CHECK_DEBUG which means the flag is allowing debugging of _REENT_CHECK macros - use #ifdef instead of #if
* Add pthread_setname_np() and pthread_getname_np()Sebastian Huber2017-01-091-0/+6
| | | | | | | The pthread_setname_np() and pthread_getname_np() are GNU extensions and provided by glibc. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

* Provide <memory.h>Sebastian Huber2016-11-221-0/+4
| | | | | | | | Provide <memory.h> for all standard Newlib targets and remove Cygwin-specific header. Most POSIX like systems provide this historic header. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* Declare non-standard pthread_yield()Sebastian Huber2016-11-221-0/+4
| | | | | | | The non-standard pthread_yield() function is available at least on Cygwin, FreeBSD and glibc. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* Move pthread types to <sys/_pthreadtypes.h>Sebastian Huber2016-11-173-230/+238
| | | | | | | | | | This makes it possible provide operating system specific types for <pthread.h>. It is in line with the FreeBSD header file structure and allows a future cleanup of <pthread.h> to not expose unrelated things via <sys/types.h> and <unistd.h>. Glibc uses the similar <bits/pthreadtypes.h> for this purpose. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* sys/cdefs.h: Define __hidden as empty on CygwinCorinna Vinschen2016-11-081-0/+5

| | | | | | | | Update the getconf utility to support the new flag as well as _PC_POSIX_PERMISSIONS and _PC_POSIX_SECURITY. These were previously unsupported, probably as an oversight. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Fix off_t typedef on Cygwin64Yaakov Selkowitz2016-08-291-1/+1
| | | | | | | | | | While both long and long long are 64-bits on x86_64, they are distinct types, and long was used prior to commit 477463a2011ba81907a753df9ce7a71b6563db54. Changing this breaks the linking of previously compiled C++ functions with off_t arguments on 64-bit Cygwin with newly compiled code, as the mangling of long (l) and long long (x) differ.

* Change loadlocale to fill a __locale_t given as parameterCorinna Vinschen2016-08-152-6/+6
| | | | | | | | | | | | Don't use global variables. This allows to call loadlocale from the yet to be created newlocale(). Rename _thr_locale_t to __locale_t (these locales are not restricted to threads so the name is misleading). Along these lines, fix _set_ctype to take a __locale_t as parameter.

* POSIX-1.2008 per-thread locales, groundwork part 1Corinna Vinschen2016-08-152-5/+26
| | | | | | | | | | | | | | | | Introduce first cut of struct _thr_locale_t used for the locale_t definition. Introduce global instance called __global_locale used by default. Introduce internal inline functions __get_global_locale, __get_locale_r, __get_current_locale. Remove usage of global variables in favor of accessor functions pointing to __global_locale for now. Include all local headers in locale subdir from setlocale.h to get single include for internal locale access. Introduce __CTYPE_PTR macro to replace direct access to __ctype_ptr__ and use throughout in isxxx functions. Signed-off by: Corinna Vinschen <corinna@vinschen.de>
* Do not include wctype.h in wchar.h with _GNU_SOURCEYaakov Selkowitz2016-08-121-1/+1

* Redefine locale info in struct _reent for per-thread localesCorinna Vinschen2016-07-061-6/+11
| | | | | | | | | | | | | The _reent members _current_category and _current_locale are not used at all. _current_locale is set to "C" in various points of the code but its value is just as unused as _current_category. This patch redefines these members without changing the size of the structure to allow for an implementation of per-thread locales per POSIX-1.2008 (i.e. uselocale and usage of the per-thread locale in subsequent function calls).
