Summary: This bug was originally fixed in http://reviews.llvm.org/D7201. However it was broken again by the fix to https://llvm.org/bugs/show_bug.cgi?id=22605. This patch re-fixes __wrap_iter with GCC by providing a forward declaration of <vector> before the friend declaration in __wrap_iter. This patch avoids the issues in PR22605 by putting canonical forward declarations in <iosfwd> and including <iosfwd> in <vector>. <iosfwd> was chosen as the canonical forward declaration headers for the following reasons: 1. `<iosfwd>` is small with almost no dependancies. 2. It already forward declares `std::allocator` 3. It is already included in `<iterator>` which we need to fix the GCC bug. This patch fixes the test "gcc_workaround.pass.cpp" Reviewers: mclow.lists, EricWF Subscribers: cfe-commits Differential Revision: http://reviews.llvm.org/D16345 git-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@261382 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.
