This removes the entire modules testing infrastructure. The current infrastructure uses CMake to generate the std and std.compat module. This requires quite a bit of plumbing and uses CMake. Since CMake introduced module support in CMake 3.26, modules have a higher CMake requirement than the rest of the LLVM project. (The LLVM project requires 3.20.) The main motivation for this approach was how libc++ generated its modules. Every header had its own module partition. This was changed to improve performance and now only two modules remain. The code to build these can be manually crafted. A followup patch will reenable testing modules, using a different approach.
libc++ Documentation ==================== The libc++ documentation is written using the Sphinx documentation generator. It is currently tested with Sphinx 1.1.3. To build the documents into html configure libc++ with the following cmake options: * -DLLVM_ENABLE_SPHINX=ON * -DLIBCXX_INCLUDE_DOCS=ON After configuring libc++ with these options the make rule `docs-libcxx-html` should be available. The documentation in this directory is published at https://libcxx.llvm.org. It is kept up-to-date by a build bot: https://lab.llvm.org/buildbot/#/builders/publish-sphinx-docs. If you notice that the documentation is not updating anymore, please contact one of the maintainers.
