C++ Language Changes in Clang ----------------------------- +- Support for the C++17 standard has been completed. This mode can be enabled + using ``-std=c++17`` (the old flag ``-std=c++1z`` is still supported for + compatibility). + +- When targeting a platform that uses the Itanium C++ ABI, Clang implements a + `recent change to the ABI`__ that passes objects of class type indirectly if they + have a non-trivial move constructor. Previous versions of Clang only + considered the copy constructor, resulting in an ABI change in rare cases, + but GCC has already implemented this change for several releases. + This affects all targets other than Windows and PS4. You can opt out of this + ABI change with ``-fclang-abi-compat=4.0``. + - As mentioned in `C Language Changes in Clang`_, Clang's support for implicit scalar to vector conversions also applies to C++. Additionally the following operators are also supported: ``&&`` and ``||``. +.. __: https://github.com/itanium-cxx-abi/cxx-abi/commit/7099637aba11fed6bdad7ee65bf4fd3f97fbf076 Objective-C Language Changes in Clang ------------------------------------- _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
