| <h1>C++ Support in Clang</h1> |
| <!--*************************************************************************--> |
| <p>Last updated: $Date$</p> |
| |
| <p>Clang fully implements all published ISO C++ standards (<a |
| href="#cxx98">C++98 / C++03</a>, <a |
| href="#cxx11">C++11</a>, and <a |
| href="#cxx14">C++14</a>), and most of the upcoming <a |
| href="#cxx17">C++17</a> standard. |
| |
| <p>The Clang community is continually striving to improve C++ standards |
| compliance between releases by submitting and tracking <a |
| href="cxx_dr_status.html">C++ Defect Reports</a> and implementing resolutions |
| as they become available.</p> |
| |
| <p>Experimental work is also under way to implement <a href="#ts">C++ Technical |
| Specifications</a> that will help drive the future of the C++ programming |
| language.</p> |
| |
| <p>The <a href="http://llvm.org/bugs/">LLVM bug tracker</a> contains Clang |
| C++ components that track known bugs with Clang's language conformance in |
| each language mode.</p> |
| |
| <h2 id="cxx98">C++98 implementation status</h2> |
| |
| <p>Clang implements all of the ISO C++ 1998 standard |
| (including the defects addressed in the ISO C++ 2003 standard) |
| except for <tt>export</tt> (which was removed in C++11). |
| |
| <h2 id="cxx11">C++11 implementation status</h2> |
| |
| <p>Clang 3.3 and later implement all of the <a |
| href="http://www.iso.org/standard/50372.html">ISO |
| C++ 2011 standard</a>. |
| |
| <p>By default, Clang builds C++ code according to the C++98 standard, with many |
| C++11 features accepted as extensions. You can use Clang in C++11 mode with the |
| <code>-std=c++11</code> option. Clang's C++11 mode can be used |
| with <a href="http://libcxx.llvm.org/">libc++</a> or with gcc's libstdc++. |

| <h2 id="dr">Defect reports</h2> |
| |
| <p>Clang generally aims to implement resolutions to Defect Reports (bug fixes |
| against prior standards) retroactively, in all prior standard versions where |
| the fix is meaningful. Significant Defect Report changes to language features |
| after the publication of the relevant standard are marked (DR) in the above |
| table.</p> |
| |
| <p>Clang also has a test suite for conformance to resolutions for issues on the |
| <a href="http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_toc.html">C++ core issues list</a>, |
| most of which are considered Defect Reports. |
| <a href="cxx_dr_status.html">Implementation status for C++ core issues</a> based on |
| that test suite is tracked on a separate page.</p> |
| |
| <h2 id="ts">Technical specifications and standing documents</h2> |
| |
| <p>ISO C++ also publishes a number of documents describing additional language |
| and library features that are not part of standard C++.</p> |
