Thanks for the update!

necessarily complete. We now have a buildbot that bootstraps Clang and runs
the test-suite with LLD:

http://lab.llvm.org:8011/builders/clang-cmake-aarch64-lld

We'll start looking at other large and complex programs next (though Clang
is quite complex and libclang is quite large already).

ARM support is coming a long way, but we're still not able to link Clang
yet, and there are some issues on the test-suite. We'll be continuing to
make progress throughout next year and hopefully have a similar buildbot on
ARM.

Rafael,

Great news about FreeBSD! Once LLD has become their default linker in
x86_64, I'd like to start the same process on AArch64.

cheers,
