This patch fixes llvm.org/PR34298. Previously libc++ incorrectly evaluated the __invokable trait via the converting constructor `function(Tp)` [with Tp = std::function] whenever the copy constructor or copy assignment operator was required. This patch further constrains that constructor to short circut before evaluating the troublesome SFINAE when `Tp` matches std::function. The original patch is from Alex Lorenz. git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@312890 91177308-0d34-0410-b5e6-96231b3b80d8
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.
