[PATCH] D120540: [Driver] Enable to use C++20 modules standalone by -fcxx-modules

[Adrian Prantl via Phabricator via cfe-commits]

aprantl added a comment.

I think the problem might be that previously on Darwin `-fcxx-modules` was used to turn on C++ Clang modules (which was not implied by `-fmodules`) without turning of C++20 (ts) modules, and after this patch `-fcxx-modules` implies `-fmodules-ts`. Does that sound plausible?
