[PATCH] D156247: [Clang] Add a warning on uses of coroutine keywords

[Tom Honermann via Phabricator via cfe-commits]

tahonermann added a comment.

At first, it sounded to me like the option that would best suit Google's needs is `-fno-coroutines`. However:

- I see that Google does have some limited use of coroutines; perhaps that could be enabled on a per-TU or project basis by the build system? However...
- The `-fno-coroutines` option doesn't seem to work; https://godbolt.org/z/Phhqjd9so (Nor does `-fcoroutines` work to enable standard library coroutine features in pre-C++20 language modes).
