[cfe-dev] Language not recognized: 'c++-module-cpp-output'

[David Blaikie via cfe-dev]

Doesn't look like this was ever tested, so I'm not sure what it was for.
I'm guessing Richard didn't consider it necessary when he removed it...

So could you outline (show a small/complete example with source, commands,
etc) what you're trying to do? You might be able to take a look at Clang's
test cases to see what's supported/implemented right now.
