2025-06-24libc: Update the guard for quick_exit() and at_quick_exit() functionsMazen Adel Elmessady1-1/+4
Updated the guard for stdlib functions to use the POSIX Issue 8 guard added in 2024.
2025-06-24libc/../pthread.h: Updated the guard for Posix Issue 8 functionsMazen Adel Elmessady1-6/+6
Updated the guard for pthread functions added in POSIX Issue 8 to use the POSIX Issue 8 guard added in 2024. These functions are: pthread_mutex_clocklock() pthread_cond_clockwait() pthread_rwlock_clockrdlock() pthread_rwlock_clockwrlock()
2025-06-24libc: Added timespec_get() to time.hMazen Adel Elmessady1-0/+5
Added timespec_get() prototype to libc/include/time.h and removed the prototype from winsup/cygwin/include/cygwin/time.h
2025-06-18add value for _h_errno in _REENT_INIT(var) for struct, _reentJohannes Rosa1-1/+2
The define '_REENT_INIT' for the case '!_REENT_SMALL' was missing an initializing value for 'int _h_errno'. If code uses the _REENT_INIT() macro to preset a variable of type struct _reent, this led to an issue when compiling with -Wmissing-field-initializers.
2025-05-02Newlib: Update search.h functions for POSIX.1-2024Mark Geisert1-4/+6
Add type posix_tnode. Change certain uses of "void" to "posix_tnode" in both the prototypes and definitions of functions associated with <search.h>. (Necessary changes to Cygwin's /usr/include/search.h will follow in a separate patch to be sent to cygwin-patches.)

2025-03-24getlocalename_l: allow LC_ALL categoryCorinna Vinschen1-2/+9
Following the changes from Austin Group bug https://www.austingroupbugs.net/view.php?id=1741, getlocalename_l() now allows to specify LC_ALL and returns a setlocale-conmpatible LC_ALL locale string. Consequentially we have to raise the size of _reent::_getlocalename_l_buf so there's enough space for the LC_ALL locale string. Guard all different definitions and usages of _getlocalename_l_buf in reent.h with _MB_CAPABLE.

setproctitle_init is defined in c2x manner, omitting names for the unused parameters.

2024-12-12Cygwin: sched_setscheduler: accept SCHED_BATCHChristian Franke1-0/+1

2024-08-21arc64: Add port for Synopsys DesignWare ARCv3 ISAYuriy Kolerov2-0/+14
Synopsys ARCv3 ISA includes 32-bit ARC HS5x targets and 64-bit ARC HS6x targets. Both CPU families are placed in "arc64" subdirectories as it done for GCC port. Target name arc64 is used for historical reasons and Synopsys ARCv3 baremetal toolchains contain multilib configurations both for 32-bit and 64-bit families. arc32 target name is reserved for 32-bit ARC HS5x targets in case of non-multilib 32-bit builds. Note that libgloss libraries for ARCv3 are compatible with libgloss for ARCv1/2. Thus, Makefile.inc for libgloss uses sources from libgloss/arc directory except crtX.S files.

This file was from a specific older FreeBSD version. There have been multiple changes to this file with FreeBSD 14 including breaking changes to the file. Including this file as part of newlib results in not always having the correct version of sys/tree.h for any specific software. RTEMS will manage its use of this file outside of newlib.

2024-07-09sys/stdatomic.h: be nicer to c++Konstantin Belousov1-0/+10
Use of stdatomic.h is undefined in C++, even the C++ 2020 standard does not list stdatomic.h as a C library header supported by the language. More, there are some subtle differences between the <atomic> C++ header, and C11+ stdatomic.h provided features. Nonetheless, it is a quality of the implementation aspect, so let mis-users mis-use stdatomic.h as they want, by making a compat shim for _Bool.

2024-07-09sys/sys: further adoption of SPDX licensing ID tags.Pedro F. Giffuni1-0/+2
Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

2024-01-31Cygwin: posix_getdents: implement per SUS Base Specifications Issue 8 draftCorinna Vinschen1-0/+3
- Basically maintain a hidden DIR* inside fhandlers. - lseek has to be tweaked to allow basic seeking on the directory descriptor. - the current implementation does not keep the dir positions between duplicated descriptor in sync. In fact, every descriptor keeps its own copy of the DIR* and after dup/fork/exec, the directory position is reset to 0, i. e., to the start of the directory, as if rewinddir() has been called on the new descriptors. While this behaviour isn't yet covered by the Issue 8 draft, a bug report along these lines exists and will probably be picked up for TC1. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

#include <locale.h> const char *getlocalename_l(int category, locale_t locobj); Most notably, we need a per-thread space to store the string returned if locobj is LC_GLOBAL_LOCALE. No errors are defined for getlocalename_l. So we can't use buffer allocation which might lead to an ENOMEM error. We have to use a "static" buffer in the per-thread state.

If specified, use __builtin_dynamic_object_size() instead of __builtin_object_size() if supported (GCC 12.0 or later). This enables buffer overflow checks if the buffer size is non-const but known during runtime. Use new macro __ssp_bos_known() instead of the (bos(p) != (size_t)-1) checks. The latter is no longer a compile time constant in all cases. This avoids the generation of unused code. Signed-off-by: Christian Franke <christian.franke@t-online.de>
