Hello,
the current Newlib build fails for aarch64 due to RTEMS-specific
patches:
CC libc/string/libc_a-wcscmp.o
../../../gnu-mirror-gcc-0f001dd/newlib/libc/machine/aarch64/setjmp.S:29:10:

Why are these patches not in upstream Newlib?
The only patch I'm aware of should be for ILP32 support in the
hand-coded AArch64 assembly in newlib.
The short answer as to why the patch isn't upstream is that newlib
hasn't committed it yet.
The longer answer is that the hand-coded AArch64 ASM in newlib is
sourced from ARM's optimized-routines repository. I provided a patch
to newlib's specifications at which point they suggested I get it
committed upstream in the optimized-routines repo, first. I did that
and then requested they pull the changes, but they were in the middle
of a release cycle. Having the patch locally was the interim solution
while we waited for that release to finish and for newlib to pull in
the changes. I'll take a look and see what the current status on that
is and what changes prompted the patch to break.
I don't see open pull requests in
https://github.com/ARM-software/optimized-routines/pulls
What is the status with respect to a Newlib integration?
All the necessary changes have been integrated into the
optimized-routines repository. I just pinged the newlib list about
integrating those changes since there doesn't seem to have been any
movement toward that goal.
