libc/include/pthread.h: Include <sched.h> instead of
<sys/sched.h>.
Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* nlsfuncs.cc (__get_lcid_from_locale): Handle LocaleNameToLCID
returning LOCALE_CUSTOM_UNSPECIFIED instead of failing in case of
an unsupported locale on Windows 10.

* signal.cc (sigwait): Fix return value to reflect errno in case of
error according to POSIX. Never return EINTR.
* thread.cc (pthread_kill): Return errno if sig_send failed.

* init.cc (munge_threadfunc): Check that we're actually replacing
the correct original function address on the stack.
* ntdll.h (enum _THREADINFOCLASS): Add ThreadQuerySetWin32StartAddress.

* strfuncs.cc (sys_cp_wcstombs): Always return number of multibytes
without trailing NUL as the documentation implies. Throughout Cygwin,
fix usage to align to this pattern.
* fhandler_process.cc (format_process_winexename): Drop trailing NUL
and LF from output.

* thread.cc (pthread_getattr_np): Fix memory leak, remove usage of
malloc for small local buffer.

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.
Import some <stdlib.h> function declarations from latest FreeBSD and
implement them. I am not sure if we should call the global reent
cleanup in quick_exit() similar to exit().
newlib/ChangeLog
2015-10-14 Sebastian Huber <sebastian.huber@embedded-brains.de>
* libc/include/stdlib.h (at_quick_exit): Declare.
(quick_exit): Likewise.
* libc/stdlib/Makefile.am (GENERAL_SOURCES): Add
quick_exit.c.
* libc/stdlib/Makefile.in: Regenerate.
* libc/stdlib/quick_exit.c: New.
- Move types and defines to
<machine/_threads.h> so that it can be customized per target.
* libc/include/threads.h: New.
* libc/sys/rtems/include/machine/_threads.h: Likewise.
* flock.cc (lockf_t::create_lock_obj_attr): Add buffer parameter.
Call _everyone_sd with buffer argument from caller rather than
everyone_sd with locally allocated stack buffer.
(lockf_t::create_lock_obj): Call create_lock_obj_attr only once
outside the loop and with additional buffer argument.
(lockf_t::open_lock_obj): Call create_lock_obj_attr with additional
buffer argument.
* cygcheck.cc (load_cygwin): Only unload cygwin DLL if not running
under a debugger. Explain why.
Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* include/sys/unistd.h (_SC_LEVEL*): Add cache-related variables as
on Linux.
* fhandler_proc.cc (format_proc_cpuinfo): Fetch cache information
from new cache functions in sysconf.cc, get_cpu_cache_intel and
get_cpu_cache_amd.
* sysconf.cc (__nt_query_system): New local helper.
(get_nproc_values): Utilize __nt_query_system on pre-Windows 7 systems.
Use GetLogicalProcessorInformationEx otherwise to handle more than
64 CPUs. Only handle _SC_NPROCESSORS_CONF and _SC_NPROCESSORS_ONLN.
(get_phys_pages): New helper to handle _SC_PHYS_PAGES.
(cpuid2_cache_descriptor): New array to map Intel CPUID 2 descriptor
values to cache type, cache size, associativity and linesize.
(cpuid2_cache_desc_compar): Comparision function for bsearch over
cpuid2_cache_descriptor.
(get_cpu_cache_intel_cpuid2): New function to fetch cache info from
Intel CPUID 2.
(get_cpu_cache_intel_cpuid4): Ditto from Intel CPUID 4.
(get_cpu_cache_intel): New function as CPU-specific entry point.
(assoc): New array to map associativity values from AMD CPUID
0x80000006.
(get_cpu_cache_amd): New function to fetch cache info from AMD CPUIDs
0x80000005 and 0x80000006.
(get_cpu_cache): New function to fetch cache info.
(sca): Call get_phys_pages if _SC_PHYS_PAGES is requested. Call
get_cpu_cache for new _SC_* cache requests.
(SC_MAX): Set to _SC_LEVEL4_CACHE_LINESIZE.
(get_phys_pages(void)): Call get_phys_pages(int).
* include/cygwin/version.h (CYGWIN_VERSION_API_MINOR): Bump.
* new-features.xml (ov-new2.3): Document sysconf cache addition.
