* Use enum __packed in favour of -fshort-enumsSebastian Huber2017-04-033-7/+3
| | | | | | | | | | | | Some architectures like ARM encode the short enum option state in the object file and the linker checks that this option is consistent for all objects of an executable. In case applications use -fno-short-enums, then this leads to linker warnings. Use the enum __packed attribute for the relevent enums to avoid the -fshort-enums compiler option. This attribute is at least available on GCC, LLVM/clang and the Intel compiler. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>
* Only define static locks in multithreaded modeThomas Preud'homme2017-02-134-0/+18
| | | | | | | | | | | | | Newlib build system defines __SINGLE_THREAD__ to allow concurrency code to be only compiled when newlib is configured for multithread. One such example are locks which become useless in single thread mode. Although most static locks are indeed guarded by !defined(__SINGLE_THREAD__), some are not. This commit adds these missing guards to __dd_hash_mutex, __atexit_recursive_mutex, __at_quick_exit_mutex and __arc4random_mutex. It also makes sure locking macros in lock.h are noop in single thread mode.
* Unify names of all lock objectsFreddie Chopin2017-02-066-23/+23
| | | | | | | | | | | | | | | | | | In preparation for the patch that would allow retargeting of locking routines, rename all lock objects to follow this pattern: "__<name>_[recursive_]mutex". Following locks were renamed: __dd_hash_lock -> __dd_hash_mutex __sfp_lock -> __sfp_recursive_mutex __sinit_lock -> __sinit_recursive_mutex __atexit_lock -> __atexit_recursive_mutex _arc4random_mutex -> __arc4random_mutex __env_lock_object -> __env_recursive_mutex __malloc_lock_object -> __malloc_recursive_mutex __atexit_mutex -> __at_quick_exit_mutex __tz_lock_object -> __tz_mutex
* Prefix consistenly target-independent locks with __Thomas Preudhomme2017-01-251-3/+3
| | | | | | | | | | | | | | | | | | | Hi, With the patch to allow newlib's locking routine to be retargeted currently under discussion, we need to start thinking of locks as part of newlib's ABI since newlib depends on specific names being provided by the OS. This patch renames 2 locks so that they follow the same naming convention as other locks. It needs to be applied before the retargeting patch, while locks are still an internal consideration. Newlib builds successfully with this change. Ok for master branch? Best regards, Thomas
* Expand comments on padding used by nano_mallocJoe Seymour2017-01-131-14/+37
| | | | | | | | | | | | | | This patch adds further comments to nano-mallocr.c, to more comprehensively explain how padding works in the malloc_chunk structure. It was originally discussed in the following thread: https://sourceware.org/ml/newlib/2017/msg00031.html 2017-01-13 Joe Seymour <joe.s@somniumtech.com> newlib/ * libc/stdlib/nano-mallocr.c (malloc_chunk, get_chunk_from_ptr) (nano_malloc): Add comments.
* Fix incorrect cast in nano mallocJoe Seymour2017-01-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As described in nano-mallocr.c, chunks of heap are represented in memory as a size (of type long), followed by some optional padding containing a negative offset to size, followed by the data area. get_chunk_from_ptr is responsible for taking a pointer to the data area (as returned by malloc) and finding the start of the chunk. It does this by assuming there is no padding and trying to read the size, if the size is negative then it uses that as an offset to find the true size. Crucially, it reads the padding area as a long. nano_malloc is responsible for populating the optional padding area. It does so by casting a pointer to an (int *) and writing the negative offset into it. This means that padding is being written as an int but read as a long. On msp430 an int is 2 bytes, while a long is 4 bytes. This means that 2 bytes are written to the padding, but 4 bytes are read from it: it has only been partially initialised. nano_malloc is the default malloc implementation for msp430. This patch changes the cast from (int *) to (long *). The change to nano_malloc has has been observed to fix a TI Energia project that had been malfunctioning because malloc was returning invalid addresses. The change to nano_memalign is based entirely on code inspection. I've built and tested as follows: Configured (gcc+newlib) with: --target=msp430-elf --enable-languages=c gcc testsuite variations: msp430-sim/-mcpu=msp430 msp430-sim/-mcpu=msp430x msp430-sim/-mcpu=msp430x/-mlarge/-mdata-region=either/-mcode-region=either msp430-sim/-mhwmult=none msp430-sim/-mhwmult=f5series My testing has shown no regressions, however I don't know if the gcc testsuite provides sufficient coverage for this patch? I don't have write access, so if this patch is acceptable after review, I would appreciate it if someone would commit it for me. Thanks, 2017-01-XX Joe Seymour <joe.s@somniumtech.com> newlib/ * libc/stdlib/nano-mallocr.c (nano_malloc): Fix incorrect cast. (nano_memalign): Likewise.

* Fix pdf build failure wrt documentation of is*_l functionsThomas Preudhomme2016-08-171-2/+2
| | | | | | | | | | | make pdf on arm-none-eabi targets fails to build after the reorganization in baf0c9fcb56e5cf8f54357bf8d8646b51b236886 to fold is*_l documentation in their is* counterpart. This is due two issues: 1) newlib/libc/ctype/ctype.tex still including the def file for the long versions 2) missing angle brackets in .c files for some of is*_l functions This patch fixes the issues and allows make pdf to succeeds.

| | | | | | | | | | | | | | | | | | | | | - Remove charset parameter from low level __foo_wctomb/__foo_mbtowc calls. - Instead, create array of function for ISO and Windows codepages to point to function which does not require to evaluate the charset string on each call. Create matching helper functions. I.e., __iso_wctomb, __iso_mbtowc, __cp_wctomb and __cp_mbtowc are functions returning the right function pointer now. - Create __WCTOMB/__MBTOWC macros utilizing per-reent locale and replace calls to __wctomb/__mbtowc with calls to __WCTOMB/__MBTOWC. - Drop global __wctomb/__mbtowc vars. - Utilize aforementioned changes in Cygwin to get rid of charset in other, calling functions and simplify the code. - In Cygwin restrict global cygheap locale info to the job performed by internal_setlocale. Use UTF-8 instead of ASCII on the fly in internal conversion functions. - In Cygwin dll_entry, make sure to initialize a TLS area with a NULL _REENT->_locale pointer. Add comment to explain why.

* Use __machine_*_t_defined for internal typesSebastian Huber2016-04-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | Newlib defines defaults for internal types via <sys/_types.h> and uses <machine/_types.h> to let targets define their own type if necessary. Previously for example #ifndef __dev_t_defined typedef short __dev_t; #endif However, the __*_t_defined pattern conflicts with the glibc type guard pattern for user types, e.g. dev_t in this example. Introduce a __machine_*_t_defined pattern for internal types (defined by <machine/_types.h>, used by <sys/_types.h>). For example #ifndef __machine_dev_t_defined typedef short __dev_t; #endif Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

It offers high quality random numbers derived from input data obtained by the OpenBSD specific getentropy() system call which is declared in <unistd.h> and must be implemented for each Newlib port externally. The arc4random() functions are used for example in LibreSSL and OpenSSH. Cygwin provides currently its own implementation of the arc4random family.
