Summary: Running the tests without availability enabled doesn't really make sense: availability annotations allow catching errors at compile-time instead of link-time. Running the tests without availability enabled allows confirming that a test breaks at link-time under some configuration, but it is more useful to instead check that it should fail at compile-time. Always enabling availability in the lit test suite will greatly simplify XFAILs and troubleshooting of failing tests, which is currently a giant pain because we have these two levels of possible failure: link-time and compile-time.

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.
