llvm dev - Jun 2020 - How to include abi and unwind tests in libcxx test suite in standalone mode

Hi Louis,

sorry for bothering you once more about the libcxx test suite! I was 
wondering whether you could help with some of my problems again.

After the recent discussion on the mailing list and your diff, I was 
able to set up cross-compilation and remote-execution of the libcxx test 
suite, so thank you for that!

We have split up the build of the libraries into different stages, so 
libcxx, libcxxabi and libunwind are all built in standalone mode. If I 
understand correctly, libcxxabi and libunwind tests are not supported 
when using this. Is there a way to include those tests when running the 
libcxx test suite?

If not, what is the recommended way to build and test those libraries 
when doing cross-compilation?

Cheers,

Dominik

I'm glad to hear that!

Yes, they are supported. It's just that I haven't implemented the
ability to use a 100% custom site config file for libcxxabi and libunwind, but
it should work just the same. I'll try doing that today -- it should be the
same dance as what I did for libcxx.

I just landed these patches:

    commit c55051eea5d3cd57abfd9727f519b670517704d9
    Author: Louis Dionne <ldionne at apple.com>
    Date:   Thu Jun 25 12:02:43 2020 -0400

        [libunwind] Allow specifying custom Lit config files

        This is the libunwind counterpart of 0c66af970c80.

    commit 33c9c10d183371edc95fa936705bef56f55ab611
    Author: Louis Dionne <ldionne at apple.com>
    Date:   Thu Jun 25 11:46:00 2020 -0400

        [libc++abi] Allow specifying custom Lit config files

        This is the libc++abi counterpart of 0c66af970c80.
