Yaakov Selkowitz 51b669f679 Do not include wctype.h in wchar.h with _GNU_SOURCE
_GNU_SOURCE generally enables all features, but in this case the POSIX
requirement to #include <wctype.h> for these is preferred.

Yaakov Selkowitz b14a1dbc86 Define va_list in stdio.h and wchar.h
This typedef, along with that of FILE in wchar.h, were XSI prior to
inclusion in POSIX.1-2008.

Yaakov Selkowitz 1e22b408b2 Include wctype.h in wchar.h as an XSI extension
However, note that this inclusion is obsolescent in SUSv4 and therefore
may be removed in the next revision.

Anton Kolesov 668033eb9f arc: Fix strcmp for big endian without barrel shifter
strcmp.S contained invalid guard for code that used barrel-shifter optional
instruction - it was checking for !ARC601 instead of whether barrel shifter
is present. While it is true that ARC601 doesn't have barrel shifter, so
does some other ARC EM configurations.

Corinna Vinschen a68ca43b90 Redefine locale info in struct _reent for per-thread locales
The _reent members _current_category and _current_locale are not
used at all.  _current_locale is set to "C" in various points of
the code but its value is just as unused as _current_category.

This patch redefines these members without changing the size of the
structure to allow for an implementation of per-thread locales per
POSIX-1.2008 (i.e. uselocale and usage of the per-thread locale in
subsequent function calls).

Wilco Dijkstra e7b1ee2ea6 Add rawmemchr
Marcus Shawcroft wrote:

Sure, I've attached the patch.

Wilco

Add a simple rawmemchr implementation. Use strlen for rawmemchr(s, '\0') as it is the
fastest way to search for '\0', and use memchr with an infinite size for other cases.
This is 3x faster for large sizes.

ChangeLog:
2016-04-22  Wilco Dijkstra  <wdijkstr@arm.com>

        * newlib/libc/machine/aarch64/Makefile.in: Add rawmemchr.S and
        rawmemchr-stub.c.
        * newlib/libc/machine/aarch64/Makefile.am: Likewise.
        * newlib/libc/machine/aarch64/rawmemchr.S (rawmemchr): Add rawmemchr.
        * newlib/libc/machine/aarch64/rawmemchr-stub.c (rawmemchr): Likewise.

Corinna Vinschen 72ded59447 Make sure to have full configuration info in sys/_types.h.
The following testcase:

  $ cat > test.c <<EOF
  #include <sys/select.h>
  #include <sys/time.h>
  EOF
  $ gcc -c test.c

emits the following error:

  /usr/include/sys/reent.h:276:3: error: expected specifier-qualifier-list befor
e ‘_fpos64_t’
     _fpos64_t _EXFNPTR(_seek64, (struct _reent *, _PTR, _fpos64_t, int));
     ^

The reason is that the load order from sys/select.h includes sys/_types.h
before sys/config.h has been included from anywhere else.  sys/_types.h
defines _fpos64_t only if __LARGE64_FILES is defined, but it never is in
this scenario.  So sys/_types.h has to make sure to get the configuration
info by itself.
