Hi!
I've got the situation, that the function strlen() occurs twice in libc.a
(building newlib for ARM-V7a and Size-Optimized).
In newlib/libc/machine/arm/strlen.c there are the pre-processor stetements ...
#if defined (__OPTIMIZE_SIZE__) || defined (PREFER_SIZE_OVER_SPEED) || \
(defined (__thumb__) && !defined (__thumb2__))
/*...*/
#else
#if !(defined(_ISA_ARM_7) || defined(__ARM_ARCH_6T2__))
/*...*/
#endif
and in newlib/libc/machine/arm/strlen-armv7.S the "exclude" begins with
/* NOTE: This ifdef MUST match the ones in arm/strlen.c
We fallback to the one in arm/strlen.c for size optimised or
for older architectures. */
#if defined(_ISA_ARM_7) || defined(__ARM_ARCH_6T2__) && \
!(defined (__OPTIMIZE_SIZE__) || defined (PREFER_SIZE_OVER_SPEED) || \
(defined (__thumb__) && !defined (__thumb2__)))
But this is not completely contrary to arm/strlen.c (see above)!
To fix the logical statement in arm/strlen-armv7.S there are parentheses needed

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.

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
