--- Comment #6 from Jonathan Wakely <redi at gcc dot gnu.org> ---
While it would be nice if the libstdc++ API docs were 100% complete and
described every piece of the library, that is never going to happen. If you=
 are
trying to use those docs to learn C++ you should stop, and look elsewhere.

The API of libstdc++ is what is described in the standard, and cppreference=
.com
does a better job of documenting it than we ever will.

So unless we suddenly run out of new features to implement and bugs to fix,=
 I
don't think anybody is going to add documentation for everything like that.

I have regenerated the latest-doxygen docs to include C++17 features:
https://gcc.gnu.org/onlinedocs/libstdc++/latest-doxygen/index.html
No is_integral_v is listed (with no description) at:
