cc142edbe7 Add the needed build system changes in order to compile and create the new libraries for Semihosting v2 for ARM.
This uses the new recursive build target in multi-build.in

The new spec files are:

For AArch32/ARM (m for mixed mode):
  - rdimon-v2m.specs
  - aprofile-validation-v2m.specs
  - aprofile-ve-v2m.specs

These spec files will be using the new libraries generated
by multi-build.in.

8a508f301c Cygwin: fix signal.h with _POSIX_C_SOURCE=1
struct sigaction is POSIX.1-1990 but siginfo_t, which is used by its
sa_sigaction member, is POSIX.1b-1993.  Therefore it needs to be guarded
as well, and as part of a union, the struct size is protected.

d2e256a36a Enable _REENT_GLOBAL_STDIO_STREAMS for RTEMS
Signed-off-by: Sebastian Huber <sebastian.huber@embedded-brains.de>

668a4c8722 Introduce _REENT_GLOBAL_STDIO_STREAMS
In Newlib, the stdio streams are defined to thread-specific pointers
_reent::_stdin, _reent::_stdout and _reent::_stderr.  In case
_REENT_SMALL is not defined, then these pointers are initialized via
_REENT_INIT_PTR() or _REENT_INIT_PTR_ZEROED() to thread-specific FILE
objects provided via _reent::__sf[3].  There are two problems with this
(at least in case of RTEMS).

(1) The thread-specific FILE objects are closed by _reclaim_reent().
This leads to problems with language run-time libraries that provide
wrappers to the C/POSIX stdio streams (e.g.  C++ and Ada), since they
use the thread-specific FILE objects of the initialization thread.  In
case the initialization thread is deleted, then they use freed memory.

(2) Since thread-specific FILE objects are used with a common output
device via file descriptors 0, 1 and 2, the locking at FILE object level
cannot ensure atomicity of the output, e.g. a call to printf().

Introduce a new Newlib configuration option _REENT_GLOBAL_STDIO_STREAMS
to enable the use of global stdio FILE objects.

As a side-effect this reduces the size of struct _reent by more than
50%.

The _REENT_GLOBAL_STDIO_STREAMS should not be used without
_STDIO_CLOSE_PER_REENT_STD_STREAMS.

c86063bdc0 Optimized memcmp
This is an optimized memcmp for AArch64.  This is a complete rewrite
using a different algorithm.  The previous version split into cases
where both inputs were aligned, the inputs were mutually aligned and
unaligned using a byte loop.  The new version combines all these cases,
while small inputs of less than 8 bytes are handled separately.

This allows the main code to be sped up using unaligned loads since
there are now at least 8 bytes to be compared.  After the first 8 bytes,
align the first input.  This ensures each iteration does at most one
unaligned access and mutually aligned inputs behave as aligned.
After the main loop, process the last 8 bytes using unaligned accesses.

This improves performance of (mutually) aligned cases by 25% and
unaligned by >500% (yes >6 times faster) on large inputs.

ChangeLog:
2017-06-28  Wilco Dijkstra  <wdijkstr@arm.com>

        * newlib/libc/machine/aarch64/memcmp.S (memcmp):
        Rewrite of optimized memcmp.
