Sebastian Huber 2693c1db69 Move ARM access.c from machine to sys
The implementation of the POSIX access() function is nothing machine
specific like memcpy(), etc.  Move it back to the system domain.  This
avoids problems due to the include search order of the Newlib/GCC build
which picks up machine includes before system includes.

Laurent ALFONSI 9b1167219a ARM/AArch64: Fix GetCmdLine semihosting directives
When simulating arm code, the target program startup code (crt0) uses
semihosting invocations to get the command line from the simulator. The
simulator returns the command line and its size into the area passed in
parameter. (ARM 32-bit specifications :
http://infocenter.arm.com/help/topic/com.arm.doc.dui0058d/DUI0058.pdf
chapter "5.4.19 SYS_GET_CMDLINE").

The memory area pointed by the semihosting register argument is located
in .text section (usually not writtable (RX)).

If we run this code on a simulator that respects this rights properties
(qemu user-mode for instance), the command line will not be written to
the .text program memory, in particular the length of the string. The
program runs with an empty command line. This problem hasn't been seen
earlier probably because qemu user-mode is not so much used, but this can
happen with another simulator that refuse to write in a read-only segment.

With this modification, the command line can be correctly passed to the
target program.

Changes:
- libgloss/arm/crt0.S : Arguments passed to the AngelSWI_Reason_GetCmdLine
  semihosting invocation are placed into .data section instead of .text
- libgloss/aarch64/crt0.S : Idem for aarch64 AngelSVC_Reason_GetCmdLine
  semihosting.

Corinna Vinschen bdb017b30c newlib: remove __infinity{f,ld} constants
previous commit 4c90db7bc8 introduced
a compile time error because libm/common/s_infconst.c used the remove
__fmath, __dmath, and __ldmath union types.

Since this is very old, and unused for a very long time, just drop the
file and thus the __infinity constants entirely.

Exception: Cygwin exports __infinity from the beginning.  There's a very,
VERY low probability that any existing executable or lib still uses this
constant, but we just keep it in for backward compat, nevertheless.

avg 3abc66ec6b don't use C99 static array indices with older GCC versions
For example, the FreeBSD GCC (4.2.1) has a spotty support for that
feature.  If the static keyword is used with an unnamed array parameter
in a function declaration, then the compilation fails with:
error: static or type qualifiers in abstract declarator

The feature does work if the parameter is named.
So, the restriction introduced in this commit can be removed when all
affected function prototypes have the workaround.

pfg 7b07f11b1f Addition of clang nullability qualifiers.
For consistency with the qualifiers added in r310977, define a new
qualifier _Null_unspecified which is also defined in clang 3.7+.

Add two new macros:
__NULLABILITY_PRAGMA_PUSH
__NULLABILITY_PRAGMA_POP

These are for use in headers when we want avoid noisy warnings if
some pointers are left without nullability annotations.

These are added with way ahead of their first use to teach the GCC
ports headers of their existance before their first use.

Probably for good, FORTIFY_SOURCE and this particular GCCism were never

even just the strong stack protector that was enabled by default.

_Nonnull
The _Nonnull nullability qualifier indicates that null is not a meaningful

_Nullable

_Nullable pointer type can be null.

These were introduced in Clang 3.7. For more information, see:
http://clang.llvm.org/docs/AttributeReference.html#nonnull

We add these now without using them so that the GCC ports have time to
