* C11 aligned_alloc() implementationSebastian Huber2015-10-191-0/+6
| | | | | | | | | | | | | | aligned_alloc() is implemented in terms of posix_memalign() which is only declared in <stdlib.h> but not defined in Newlib in general. At least Linux and RTEMS implement this function. newlib/ChangeLog 2015-10-14 Sebastian Huber <sebastian.huber@embedded-brains.de> * libc/stdlib/Makefile.am (GENERAL_SOURCES): Add alloc_aligned.c.c. * libc/stdlib/Makefile.in: Regenerate. * libc/stdlib/aligned_alloc.c: New.

* strlen-armv7.S: Fix preprocessor checkCorinna Vinschen2015-08-271-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Hi! I've got the situation, that the function strlen() occurs twice in libc.a (building newlib for ARM-V7a and Size-Optimized). In newlib/libc/machine/arm/strlen.c there are the pre-processor stetements ... #if defined (__OPTIMIZE_SIZE__) || defined (PREFER_SIZE_OVER_SPEED) || \ (defined (__thumb__) && !defined (__thumb2__)) /*...*/ #else #if !(defined(_ISA_ARM_7) || defined(__ARM_ARCH_6T2__)) /*...*/ #endif and in newlib/libc/machine/arm/strlen-armv7.S the "exclude" begins with /* NOTE: This ifdef MUST match the ones in arm/strlen.c We fallback to the one in arm/strlen.c for size optimised or for older architectures. */ #if defined(_ISA_ARM_7) || defined(__ARM_ARCH_6T2__) && \ !(defined (__OPTIMIZE_SIZE__) || defined (PREFER_SIZE_OVER_SPEED) || \ (defined (__thumb__) && !defined (__thumb2__))) But this is not completely contrary to arm/strlen.c (see above)! To fix the logical statement in arm/strlen-armv7.S there are parentheses needed Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

| | | | | | | | | | | Sorry, there was a typo in <sys/lock.h> which leads to memory corruption since not enough space is reserved for the lock object. newlib/ChangeLog 2015-07-30 Sebastian Huber <sebastian.huber@embedded-brains.de> * libc/sys/rtems/include/sys/lock.h (__LOCK_INIT_RECURSIVE): Use proper type.
* [AArch64] Rewrite optimized memset.Wilco Dijkstra2015-07-301-0/+4
| | | | | | | | | | | This is an optimized memset for AArch64. Memset is split into 4 main cases: small sets of up to 16 bytes, medium of 16..96 bytes which are fully unrolled. Large memsets of more than 96 bytes align the destination and use an unrolled loop processing 64 bytes per iteration. Memsets of zero of more than 256 use the dc zva instruction, and there are faster versions for the common ZVA sizes 64 or 128. STP of Q registers is used to reduce codesize without loss of performance.
* Move header filesSebastian Huber2015-07-291-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | During libgcc build the first include search path for <...> is "../newlib/libc/sys/rtems/include". Move all RTEMS specific header files to "libc/sys/rtems/include" so that they can be found. Later during libc build the header files in the previous location were somehow present, but for libgcc build they were invisible. This change is necessary to use <pthread.h> for the GCC thread model implementation. newlib/ChangeLog 2015-07-27 Sebastian Huber <sebastian.huber@embedded-brains.de> libc/sys/rtems/machine/_types.h: Move to ... libc/sys/rtems/include/machine/_types.h: ... here. libc/sys/rtems/machine/limits.h: Move to ... libc/sys/rtems/include/machine/limits.h: ... here. libc/sys/rtems/machine/param.h: Move to ... libc/sys/rtems/include/machine/param.h: ... here. libc/sys/rtems/sys/cpuset.h: Move to ... libc/sys/rtems/include/sys/cpuset.h: ... here. libc/sys/rtems/sys/dirent.h: Move to ... libc/sys/rtems/include/sys/dirent.h: ... here. libc/sys/rtems/sys/param.h: Move to ... libc/sys/rtems/include/sys/param.h: ... here. libc/sys/rtems/sys/syslimits.h: Move to ... libc/sys/rtems/include/sys/syslimits.h: ... here. libc/sys/rtems/sys/utime.h: Move to ... libc/sys/rtems/include/sys/utime.h: ... here.

* [AArch64] Optimized memcpy.Wilco Dijkstra2015-07-131-0/+5
| | | | | | | | | | This is an optimized memcpy for AArch64. Copies are split into 3 main cases: small copies of up to 16 bytes, medium copies of 17..96 bytes which are fully unrolled. Large copies of more than 96 bytes align the destination and use an unrolled loop processing 64 bytes per iteration. In order to share code with memmove, small and medium copies read all data before writing, allowing any kind of overlap. On a random copy test memcpy is 40.8% faster on A57 and 28.4% on A53.
* [AArch64] Optimized memmove.Wilco Dijkstra2015-07-131-0/+5
| | | | | | | This is an optimized memmove for AArch64. All copies of up to 96 bytes and all backward copies are done by the new memcpy. The only remaining case is large forward copies which are done in the same way as the memcpy loop, but copying from the end rather than the start.
* Rework handling of basename variantsYaakov Selkowitz2015-07-061-0/+9
| | | | | | | | | | | | | | | | As a commonly-included header, the #define basename in <string.h> can affect code which uses "basename" for its own purposes (e.g. struct members or C++ namespaced functions). When such cases occur and some code includes <string.h> and some not, then errors result. OTOH, <libgen.h> is rarely used, and that's where the renaming occurs in glibc, so code using <libgen.h> should already be safe. * libc/include/libgen.h (basename): Define as __xpg_basename for source compatibility with glibc. Declare with __ASMNAME("basename") for ABI compatibility. * libc/include/string.h (basename): Define as basename for source compatibility with glibc. Declare with __ASMNAME("__gnu_basename") for ABI compatibility.
* Fix sys/time.h build problem due to inconsistent macro usageCorinna Vinschen2015-07-061-0/+6
| | | | | | | | | | | | | https://sourceware.org/ml/newlib/2015/msg00520.html describes how sys/time.h uses __BSD_VISIBLE while the types used in the affected inline functions are guarded with !_POSIX_SOURCE. Fix that by guarding the type with __BSD_VISIBLE as well. * libc/include/sys/time.h: Explicitely include sys/cdefs.h. * libc/include/sys/types.h: Ditto. Guard BSD convenience base types with __BSD_VISIBLE rather than !_POSIX_SOURCE. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Prevent use of uninitialized file lockSebastian Huber2015-07-021-0/+6
| | | | | | | | | | | | | | | The CHECK_INIT() is necessary before the _newlib_flockfile_start() since this would use otherwise acquire an uninitialized lock which gets initialized after this leading to a corrupt release. newlib/ChangeLog 2015-07-01 Sebastian Huber <sebastian.huber@embedded-brains.de> libc/stdio/fputs.c (_puts_r): Add missing CHECK_INIT(). libc/stdio/gets.c (_gets_r): Add missing _REENT_SMALL_CHECK_INIT() and CHECK_INIT().
