So this is AARCH64, which is ARM 64 bit. Although I think Intel manufactures
some of those
(see the top end Altera FPGAs), we don’t have any to play with in the OpenMP
team, so we can't easily help.

I don't know *exactly* how you're building this or which OS or hw.. I
don't see these problems so will need more details. The Intel guys may know
the perl scripts better than me.. I don't really see how those can be the
root of the problem.

Is there an open issue for this?

So, I got some dependency errors while building OpenMP on my AArch64 box:

cd /home/rengolin/devel/llvm/release/rc3/Phase3/openmp/src &&
/usr/bin/perl
/home/rengolin/devel/llvm/release/rc3/openmp.src/runtime/tools/check-depends.pl
--os=lin --arch=aarch64
--expected="libdl.so.2,libgcc_s.so.1,libpthread.so.0"
/home/rengolin/devel/llvm/release/rc3/Phase3/openmp/src/libomp.so
check-depends.pl: (i) Dependencies:
check-depends.pl: (i) libc.so.6
check-depends.pl: (i) libdl.so.2
check-depends.pl: (i) libpthread.so.0
check-depends.pl: (x) Unexpected dependencies:
check-depends.pl: (x) libc.so.6

I remember those problems when I tried last year, and they should be
not too hard to work around. However, we're late in the release and I
don't want to delay it even more for an experimental feature.

It should be fine to compile it separately and upload later. But it
would be better if you could work on the release and OMP scripts to
make it work out of the box, so we can do the next releases without
delay.

I'll continue without OMP for now.

cheers,
