[cfe-dev] Has std::compare_3way been implemented yet?

[Fletcher, John P via cfe-dev]

I see from the status page that the implementation status of <=> for C++2a is described as Partial.  I have started to use this with Clang 7.0 rc2 (I have the release but have not built it yet).

I think I need std::compare_3way and have not been able to find it in what I have.

Has it now been implemented?

Thanks
