  "message": "[libc++] Fix and document visibility attributes for Clang, GCC and Windows.\n\nSummary:\nThis patch fixes a number of problems with the visibility macros across GCC (on Unix) and Windows (DLL import/export semantics). All of the visibility macros are now documented under `DesignDocs/VisibilityMacros.rst`. Now I\u0027ll no longer forget the subtleties of each!\n\nThis patch adds two new visibility macros:\n\n* `_LIBCPP_ENUM_VIS` for controlling the typeinfo of enum types. Only Clang supports this.\n* `_LIBCPP_EXTERN_TEMPLATE_TYPE_VIS` for redefining visibility on explicit instantiation declarations. Clang and Windows require this.\n\nAfter applying this patch GCC only emits one -Wattribute warning opposed to 30+.\n\n\nReviewers: mclow.lists, EricWF\n\nSubscribers: beanz, mgorny, cfe-commits\n\nDifferential Revision: https://reviews.llvm.org/D24602\n\ngit-svn-id: https://llvm.org/svn/llvm-project/libcxx/trunk@281673 91177308-0d34-0410-b5e6-96231b3b80d8\n",
