Tamar Christina d7d6ad7b6b Add support for Semihosting v2 support for ARM in libgloss.
Semihosting v2 changes are documented here:
https://developer.arm.com/docs/100863/latest/

The biggest change is the addition of an extensions mechanism
to add more extensions in the future.

Tamar Christina 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.

Tamar Christina bfa3bbcf33 Adds the needed build system changes in order to compile and create the new libraries for Semihosting v2.
This uses the new recursive build target in multi-build.in

For AArch64 no new spec files are needed but the makefiles
are modified to keep them in sync with the ARM ones.

Tamar Christina ebd97f4c00 Create a recursive make target that is modeled after the existing multilib makefile config-ml.in which can be used to build the same files within a target multiple ways.
e.g. from the same source file produce multiple libs by varying the
options passed to the compiler.

Yaakov Selkowitz 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.

Sebastian Huber 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.

Wilco Dijkstra 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.

Sebastian Pop 9938a64ca9 aarch64: optimize the unaligned case of memcmp
This brings to newlib a performance improvement that we developed in Bionic
libc.  That change has been submitted for review to Bionic libc:
https://android-review.googlesource.com/418279

A similar patch has been submitted for review in glibc:
https://sourceware.org/ml/libc-alpha/2017-06/msg01143.html

Patch written by Vikas Sinha and Sebastian Pop.

The performance was measured on the bionic-benchmarks on a hikey (aarch64 8xA53)
board. There was no performance change to the existing benchmark
and a performance improvement on the new benchmark for memcmp
on the unaligned side. The new benchmark has been submitted for
review at https://android-review.googlesource.com/414860

The overall performance improves by 18% for the small data set 8
and the performance improves by 450% for the large data set 64k.

The base is with the libc from /system/lib64. The bionic libc
with this patch is in /data.

Fujii Hironori 4d336756fa cygwin: regtool: encode error messages correctly
Error messages of regtool can't be read, which are encoded in,
for instance, SHIFT_JIS in Japanese Windows.  Fix by using
wide chars instead of multibyte.
