* headers: avoid bareword attributesEric Blake2017-08-172-15/+15
| | | | | | | | | Always use the __-decorated form of an attribute name in public headers, as the bareword form is in the user's namespace, and we don't want compilation to break just because the user defines the bareword to mean something else. Signed-off-by: Eric Blake <eblake@redhat.com>

* Proper locking for getchar() and putchar()Sebastian Huber2017-08-071-7/+32
| | | | | | | | | | | | | 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(). Define getchar() and putchar() to these unlocked internal functions if __SINGLE_THREAD__ is defined, otherwise use the external functions to use proper locking of the FILE object. Assumes that __SINGLE_THREAD__ is not defined if __CYGWIN__ is defined. Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

* arm: Update strcpy.c to use UAL syntax.Ian Tessier via newlib2017-07-201-6/+7
| | | | | | | | | | | | | With this change the arm platform can now be fully compiled with Clang. Tested by comparing the output with GCC 4.8.2, and Clang 4.0, using a variety of arches, big/little endianness, and arm/thumb mode to verify the generated assembly output matches between GCC vs Clang with UAL, and also GCC with UAL vs GCC with non-UAL, for all preprocessor code blocks. The only difference found is an extra nop at the end of the function when compiled with GCC using armv7-a/thumb/little-endian/-O2 compared to Clang. The nop is not emitted when compiled in big-endian mode.

* Introduce _REENT_GLOBAL_STDIO_STREAMSSebastian Huber2017-06-302-6/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Optimized memcmpWilco Dijkstra2017-06-291-193/+113

This is a complete rewrite using a different algorithm. The previous version split into cases where both inputs were aligned, the inputs were mutually aligned and unaligned using a byte loop. The new version combines all these cases, while small inputs of less than 8 bytes are handled separately. This allows the main code to be sped up using unaligned loads since there are now at least 8 bytes to be compared. After the first 8 bytes, align the first input. This ensures each iteration does at most one unaligned access and mutually aligned inputs behave as aligned. After the main loop, process the last 8 bytes using unaligned accesses. This improves performance of (mutually) aligned cases by 25% and unaligned by >500% (yes >6 times faster) on large inputs.
