Our documentation for running LIT is basically wrong, since it doesn't mention `llvm-lit`, and nothing works without it. Note that this documentation improvement reflects the current reality outside of the recent efforts on improving the test suite. My goal is to document the current way of running the test suite, so that everybody agrees on how things currently work. As the configuration system for libc++ gets simplified, we can come back and keep this documentation up to date to reflect those changes. Differential Revision: https://reviews.llvm.org/D77673
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.
