Pieter du Preez 264b817b8e Define the newlib version macros in one place: _newlib_version.h.
Currently, the newlib version information needs to be updated in two places:
 - newlib/acinclude.m4
 - newlib/libc/include/sys/features.h

The goal of this patch is to:
 - supply a single location for defining the newlib version
   information: newlib/acinclude.m4
 - define __NEWLIB__, __NEWLIB_MINOR__ and __NEWLIB_PATCHLEVEL__
   This is in line with what gcc does for its version macros. See:
   https://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html

This patch moves the definition of the _NEWLIB_VERSION, __NEWLIB__
and __NEWLIB_MINOR__ macros from newlib/libc/include/sys/features.h,
to the newly generated newlib/_newlib_version.h file. Additionally,
the __NEWLIB_PATCHLEVEL__ macro was created, for completeness.

In order to stay backwards compatible, newlib/_newlib_version.h gets
included by newlib/newlib.h and newlib/libc/include/sys/features.h.

Note: This patch does _not_ include the modifications to the following
files, as these should all be generated any way.
      *Makefile.in,
      *aclocal.m4,
      *configure
      stamp-* files

Jon Turney c5fee55606 stdio.h: Use __POSIX_VISIBLE etc. guards for POSIX 1003.1:2001 functions
Current mesa expects stdio.h to prototype fileno() when compiling with gcc
-std=c99 -D_XOPEN_SOURCE

Fix the 'POSIX 1003.1:2001' block in stdio.h to prototype functions if not
__STRICT_ANSI__, or _BSD_SOURCE, _POSIX_C_SOURCE or _XOPEN_SOURCE are defined
appropriately

As far as I can tell, despite being in this block, setbuffer() and setlinebuf()
are BSDisms which aren't in POSIX 1003.1:2001

Игорь Веневцев 352cdbb012 Newlib build is broken if configured with nano-malloc and non-reentrant system calls
Non-reentrant system calls version implies both MISSING_SYSCALL_NAMES
and REENTRANT_SYSCALL_PROVIDED macros to be defined.
Being coupled with --enable-newlib-nano-malloc knob it breaks the build:

bash-4.3$ ../newlib-2.3.0.20160104/configure CC_FOR_TARGET=gcc
AR_FOR_TARGET=ar RANLIB_FOR_TARGET=ranlib CFLAGS_FOR_TARGET="-m32
-DMISSING_SYSCALL_NAMES -DREENTRANT_SYSCALLS_PROVIDED"
--target=i386-elf --enable-newlib-nano-malloc && make

<...omitted output...>

In function ‘_mallinfo_r’:
../../../../../../newlib-2.3.0.20160104/newlib/libc/stdlib/nano-mallocr.c:489:35:

Makefile:1512: recipe for target 'lib_a-nano-mallinfor.o' failed
make[8]: *** [lib_a-nano-mallinfor.o] Error 1

In case of non-reentrant system calls _sbrk_r became a macro with TWO
args (defined in reent.h):

#define _sbrk_r(__reent, __incr)  sbrk(__incr)

But in our case only one argument is present. (RCALL 0) is considered
as a single argument despite RCALL itself is a macro:)

So intermediate one-arg macro will be enough to expand args before
final _sbrk_r expansion:

#define _SBRK_R(X) _sbrk_r(X)

Anton Kolesov 06537f05d4 ARC: Use new definitions for optional ARC CPU features
GCC for ARC has been updated to provide consistent naming of preprocessor
definitions for different optional architecture features:

    * __ARC_BARREL_SHIFTER__ instead of __Xbarrel_shifter for
      -mbarrel-shifter
    * __ARC_LL64__ instead of __LL64__ for -mll64
    * __ARCEM__ instead of __EM__ for -mcpu=arcem
    * __ARCHS__ instead of __HS__ for -mcpu=archs
    * etc (not used in newlib)

This patch updates assembly routines for ARC to use new definitions instead
of a deprecated ones. To ensure compatibility with older compiler new
definitions are also defined in asm.h if needed, based on deprecated
preprocessor definitions.

Thomas Preud'homme 5b9873fa72 Check for 64 FP instructions availability in libm before using them
Currently, double precision math functions in newlib/libm/machine/arm detect whether neon instructions can be used for double precision computation by checking the architecture version (>= 8) and the availability of floating-point instructions. However, these instructions would not be available if targeting fpv5-sp-d16 as the FPU, which by definition does not have 64bit float instructions. This patch adds a check that __ARM_FP advertises 64bit float instructions.

Marcus Shawcroft dc38827570 [ARM] Factor out the thumb2 -Os implementation.
The patch moves the inline ASM thumb2 -Os implementation out into its
own .S file.

Tested by building newlib and comparing libc.a binaries before and
after for all permutations of:

      Architectures:
        armv4 armv4t armv5 armv5t armv5te armv6 armv6j armv6k
        armv6z armv6kz armv6t2 armv6-m armv6s-m armv7 armv7-a
        armv7ve armv7-r armv7-m armv7e-m armv8-a iwmmxt iwmmxt2

      ISAs:
        thumb arm

      Optimization Levels:
        Os O2

      Excluding:
        armv6s-m -mthumb
        armv6-m -mthumb

        armv6zk -mthumb
        armv6z -mthumb
        armv6k -mthumb
        armv6j -mthumb

Jon Turney 21e6ba20ae Improve markup of sscanf and swscanf documentation
- use bullet points to separate width, size and type sections, rather than using
rows in an enormous table, for consistency with sprintf and swprintf.

- use code markup for size bullet point for consistency

- use a texinfo multitable for description of the size flags, rather than some
preformatted text

- tidy up some whitespace so type flags are all aligned
