* Arrange for text mode on stdin, stdout and stderr.Kaz Kylheku2017-11-171-0/+20
| | | | | | * newlib/libc/stdio/findfp.c (__sinit): Add the Cygwin-specific __SCLE (stream convert line endings) flag when calling the std function to initializing the reent structure's _stdin, _stdout and _stderr members.

| | | | | | | | * newlib/libc/stdio/flags.c (__sflags): Enable for Cygwin the piece of code which adds the O_TEXT mode if O_BINARY is not present. And, also, fix that piece of code's incorrect use of the | operator to test a flag instead of &.

* Revert "headers: avoid bareword attributes" for clangEric Blake2017-08-251-14/+16
| | | | | | | | | | | | | | | This reverts most of commit 979d467ff6e39ee5c52cf1aac7a6c9c63058141c. We cannot avoid some bareword attributes until clang is fixed to properly support __-decorated attributes; see this bug: https://bugs.llvm.org/show_bug.cgi?id=34319 The macros in question expand to the empty string under gcc, so only compilation under clang is affected, and since clang has the bug, the obvious solution is to roll back the changes, and document the issue.

* 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>

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.
