Hello,
the current Newlib build fails for aarch64 due to RTEMS-specific
patches:
CC libc/string/libc_a-wcscmp.o

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 just rebuilt this on the current RTEMS6 GCC10 branch with current
newlib (ed32020) and had no problems building it. It's odd that the file
is missing given that it's newly written by the patch. What else is
necessary to reproduce the build failure?
