2023-08-15struct _reent: add state for unicode functionsCorinna Vinschen1-0/+16
C23 requires that the unicode functions c16rtomb, c8rtomb, mbrtoc16, mbrtoc32 and mbrtoc8 use their own internal state object. c32rtomb only needs an internal state if the lib supports encoding with shift states, but that's the case for newlib and Cygwin. Only Cygwin implements these functions so add the states objects only for Cygwin for now. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2023-08-07sys/cdefs.h: introduce __restrict_arr, as in glibcCorinna Vinschen1-0/+13
C99 allows to define arrays as non-overlappiung using the restrict keyword. This is supported by GCC 3.1 and later, but it's not allowed in C++. This is in preparation of fixing a Cygwin build problem introduce by commit 3c75fac130b5. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2023-08-07sys/cdefs.h: fix for use __restrict in C++Sebastian Huber1-9/+7
Newlib shares large parts of <sys/cdefs.h> with FreeBSD and received this bug report: https://sourceware.org/pipermail/newlib/2023/020400.html As an extension, GCC and clang offer C99-style restricted pointers in C++ mode: https://gcc.gnu.org/onlinedocs/gcc/Restricted-Pointers.html We notice that this extension is broken when including newlib headers: restricted pointers are treated as ordinary pointers. We traced this to the following section of newlib/libc/include/sys/cdefs.h: /* * GCC 2.95 provides `__restrict' as an extension to C90 to support the * C99-specific `restrict' type qualifier. We happen to use `__restrict' as * a way to define the `restrict' type qualifier without disturbing older * software that is unaware of C99 keywords. */ #if !(__GNUC__ == 2 && __GNUC_MINOR__ == 95) #if !defined(__STDC_VERSION__) || __STDC_VERSION__ < 199901 #define __restrict #else #define __restrict restrict #endif #endif While the GCC __restrict extension was indeed introduced in GCC 2.95, it is not limited to this version; the extension is also not limited to C90: https://gcc.gnu.org/gcc-2.95/c++features.html Rewrite the logic in the header so that __restrict is kept alone when available.

2023-08-02newlib: Fix memory leak regarding gdtoa-based _ldtoa_r().Takashi Yano2-13/+14
After the commit a4705d387f78, printf() for floating-point values causes a memory leak. The legacy _ldtoa_r() assumed the char pointer returned will be free'ed by Bfree(). However, gdtoa-based _ldtoa_r() returns the pointer returned by gdtoa() which should be free'ed by freedtoa(). Due to this issue, the caller of _ldtoa_r() fails to free the allocated char buffer. This is the cause of the said memory leak. https://cygwin.com/pipermail/cygwin/2023-July/254054.html This patch makes rv_alloc()/freedtoa() allocate/free the buffer in a compatible way with legacy _ldtoa_r().

2023-07-31Revert "* libc/stdlib/mbtowc_r.c (__ascii_mbtowc): Disallow conversion of"Corinna Vinschen2-12/+0
This reverts commit 2b77087a48ea56e77fca5aeab478c922f6473d7c. For some reason lost in time, commit 2b77087a48ea5 introduced Cygwin-specific code treating single byte characters outside the portable character set as illegal chars. However, Cygwin was always alone with this over-correct behaviour and it leads to stuff like gnulib replacing functions defined in Cygwin with their own implementation just due to that. Revert this change, sans the changes to ChangeLog. Fixes: 2b77087a48ea ("* libc/stdlib/mbtowc_r.c (__ascii_mbtowc): Disallow conversion of") Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2023-07-27Fix rounding results in lrint() & llrint() when close to 0Jesse Huang via Newlib4-48/+26
soft-fp should round floating pointer numbers according to the current rounding mode. However, in the current code of lrint() and llrint(), there are if statements before the actual rounding computation if(j0 < -1) return 0; Where j0 is the exponent of the floating point number. It means any number having a exponent less than -1 (i.e. interval (-0.5, 0.5)) will be rounded to 0 regardeless of the rounding mode. The bug already fixed in glibc in 2006 by moving the check afterwards the rounding computation, but still persists in newlib. This patch fixed it in a similar way to glibc Ref Commit in glibc: 6624dbc07b5a9fb316ed188ef01f65b8eea8b47c

search paths For example, for GCC/GCN target (AMD GPUs), target libraries are built individually per supported hardware ISA ('-march=[...]'). Testing such a toolchain via, for example: $ make RUNTESTFLAGS='--target_board=[...]/-march=gfx90a' check[...] ... does work fine for all 'check-gcc-[...]' as well as GCC-provided target libraries, 'check-target-[...]'. Just for 'check-target-newlib', for the example above, not the '-march=gfx90a' newlib libraries are linked in, but instead always the default ones, which results in link FAILure. This is cured simply by skipping use of 'newlib/testsuite/lib/flags.exp', so that the standard search paths as determined by GCC, DejaGnu are used for newlib, too.

2023-02-24Cygwin: convert Windows locale handling from LCID to ISO5646 stringsCorinna Vinschen1-1/+1
Since Windows Vista, locale handling is converted from using numeric locale identifiers (LCID) to using ISO5646 locale strings. In the meantime Windows introduced new locales which don't even have a LCID attached. Those were unusable in Cygwin because locale information for these locales required to call the new locale functions taking a locale string. Convert Cygwin to drop LCIDs and use Windows ISO5646 locales instead. The last place using LCIDs is the __set_charset_from_locale function. Checking numerically is easier and uslay faster than checking strings. However, this function is clearly a TODO
