Here we describe the -status of libc++ in some detail, including major improvements from the previous -release and new feature work. For the general LLVM release notes, see `the LLVM -documentation <https://llvm.org/docs/ReleaseNotes.html>`_. All LLVM releases may -be downloaded from the `LLVM releases web site <https://releases.llvm.org/>`_. - -For more information about libc++, please see the `Libc++ Web Site -<https://libcxx.llvm.org>`_ or the `LLVM Web Site <https://llvm.org>`_. - -What's New in Libc++ 8.0.0? -=========================== - -API Changes ------------ -- Building libc++ for Mac OSX 10.6 is not supported anymore. -- Starting with LLVM 8.0.0, users that wish to link together translation units - built with different versions of libc++'s headers into the same final linked - image MUST define the _LIBCPP_HIDE_FROM_ABI_PER_TU macro to 1 when building - those translation units. Not defining _LIBCPP_HIDE_FROM_ABI_PER_TU to 1 and - linking translation units built with different versions of libc++'s headers - together may lead to ODR violations and ABI issues. On the flipside, code - size improvements should be expected for everyone not defining the macro. -- Starting with LLVM 8.0.0, std::dynarray has been removed from the library. - std::dynarray was a feature proposed for C++14 that was pulled from the - Standard at the last minute and was never standardized. Since there are no - plans to standardize this facility it is being removed. -- Starting with LLVM 8.0.0, std::bad_array_length has been removed from the - library. std::bad_array_length was a feature proposed for C++14 alongside - std::dynarray, but it never actually made it into the C++ Standard. There - are no plans to standardize this feature at this time. Formally speaking, - this removal constitutes an ABI break because the symbols were shipped in - the shared library. However, on macOS systems, the feature was not usable - because it was hidden behind availability annotations. We do not expect - any actual breakage to happen from this change. |
