This fixes a long-standing problem when GetProcAddress fails
to load a function. The noload code calls SetLastError on
i686 without saving the edx register. Starting with Windows 7,
SetLastError apparently uses $edx and the register is set to
0x00000000 on return. So the subsequent `jmp *$edx' in noload
supposed to return to the caller, actually jumps to address NULL,
which results in a SEGV.
* autoload.cc (noload): i686 only: Save and restore $edx when calling
SetLastError to avoid clobbering return address stating with Windows 7.

Subject: [PATCH] Updated general Copyright notice
Hi,
As I mentioned recently [1], newlib is providing a "kill" symbol to link
against, without declaring "kill" in signal.h. This is confusing for the
libgfortran build, which tries to link against kill (which succeeds), then
tries to use it (which triggers -Werror=implicit-function-declaration).
This patch implements my suggestion in that thread - making the declaration
of 'kill' in libc/include/sys/signal.h unconditional.
I've tested this by building a modified libgfortran on AArch64/ARM to see
that the Werror goes away, and the libgfortran build succeeds.
Is something like this OK for newlib? If so, can someone please commit
it on my behalf, as I have no commit access here.
Otherwise, what is your preferred direction for me to take this patch?
Thanks,
James

So it seems this problem has been around for a while, and looks like it
is due to a change in texi2dvi in texinfo 5.0 or late 4.x, see [1].
I guess it's not very noticeable since it only occurs when doing 'make
dvi', which doesn't happen by default.
Attached is a different and perhaps cleaner workaround to the one in
that thread.

Hi Richard,
ARM's machine/param.h that is included in "#include <machine/param.h>",
before the 'ifndef' already defines HZ to be 100. This file was already
there, it was just not being used. I understand that this 'ifndef' might
be confusing, though I decided to add it to mimic the behavior of the
default sys/param.h.
There is however an unrelated issue with this patch, a typo in the
"#define NOFILE" that crept in there due to some copy pasting when
splitting the patch.
Here is a fixed version.
BR,
Andre

Allow exceptions to be nested, which is especially useful with urgent
interrupts while processing an exception.
The implementation counts up the nesting level with each call to an
exception. In the outer exception (level 1), the exception stack is
started. All nested exceptions just reserve the redzone (scratch
memory that may be used by compiler) and exception context on the
stack, but then process on the same scratch.
Restriction: Impure pointers are shared among all exceptions. This may
be solved by creating an impure data structure in the stack frame with
each nested exception.
* or1k/crt0.S: Add exception nesting
* or1k/exceptions-asm.S: ditto

* libc/sys/rtems/include/sys/lock.h (__LOCK_INIT_RECURSIVE): Use
proper type.
This is an optimized memset for AArch64. Memset is split into 4 main
cases: small sets of up to 16 bytes, medium of 16..96 bytes which are
fully unrolled. Large memsets of more than 96 bytes align the
destination and use an unrolled loop processing 64 bytes per
iteration. Memsets of zero of more than 256 use the dc zva
instruction, and there are faster versions for the common ZVA sizes 64
or 128. STP of Q registers is used to reduce codesize without loss of
performance.

During libgcc build the first include search path for <...> is
"../newlib/libc/sys/rtems/include". Move all RTEMS specific header
files to "libc/sys/rtems/include" so that they can be found. Later
during libc build the header files in the previous location were somehow
present, but for libgcc build they were invisible. This change is
necessary to use <pthread.h> for the GCC thread model implementation.
