| <h1>C++ and C++'0x Support in Clang</h1> |
| <!--*************************************************************************--> |
| <p>Last updated: $Date$</p> |
| |
| <p>Clang currently implements all of the ISO C++ 1998 standard |
| (including the defects addressed in the ISO C++ 2003 standard) |
| except for 'export' (which has been removed from the C++'0x draft) |
| and is considered a production-quality C++ compiler. The <a |
| href="http://llvm.org/bugs/">LLVM bug tracker</a> contains a Clang |
| C++ component that tracks known Clang C++ bugs.</p> |
| |
| <h2 id="cxx0x">C++0x Implementation status</h2> |
| |
| <p>Clang provides support for a number of features included in the upcoming ISO C++ Standard, C++0x. This section tracks the status of various C++0x |
| features, and a number of other C++0x features are under active development.</p> |
| |
| <p>You can use Clang in C++0x mode either |
| with <a href="http://libcxx.llvm.org/">libc++</a> or with gcc's libstdc++. |
| libstdc++-4.4 requires <a href="libstdc++4.4-clang0x.patch">a patch</a> to work |
| with clang; other versions have not been tested.</p> |
| |
| |
| <!-- Within this table: The colors we're using to color-code our level |
| of support for a given section: |
| |
| White (no background): not considered/tested. |
| #C11B17: Broken. |
| #F88017: Some useful examples work |
| #FDD017: Many examples work |
| #347C17: Nearly everything works |
| #00FF00 + check mark: Implementation complete! |
| --> |
| |
| <p>The following table is used to help track our implementation |
| progress toward implementing the complete C++'0x standard. We use a |
| simple, somewhat arbitrary color-coding scheme to describe the |
| relative completeness of features:</p> |
| |
| <table width="689" border="1" cellspacing="0"> |
| <tr> |
| <th>Not started/not evaluated</th> |
| <th>Not Applicable</th> |
| <th>Broken</th> |
| <th>Some examples work</th> |
| <th>Many examples work</th> |
| <th>Nearly everything works</th> |
| <th>Complete</th> |
| <!-- |
| <th>Complete (with tests for each paragraph)</th> |
| --> |
| </tr> |
| <tr> |
| <td></td> |
| <td class="na">N/A</td> |
| <td class="broken"></td> |
| <td class="basic"></td> |
| <td class="medium"></td> |
| <td class="advanced"></td> |
| <td class="complete">rXXXXXX</td> |
| <!-- |
| <td class="complete" align="center">✓</td> |
| --> |
| </tr> |
| </table> |
| |
| <p>In addition, boxes marked with ✓ have complete and passing tests. |
| Similarly, boxes marked with ✗ have complete tests, some of which |
| are failing, and a <b>?</b> indicates partial tests while not making any |
| statement about passing status.</p> |
| |
| <p>A feature is "complete" when the appropriate Clang component (Parse, AST, |
| Sema, CodeGen) implements the behavior described in all of the |
| paragraphs in the relevant C++'0x draft standard. The major |
| components are:</p> |
| |
| <dl> |
| <dt>Parse</dt> |
| <dd>Clang is able to parse the grammar of this feature (or the grammar |
| described by this section), but does not necessarily do anything with the |
| parsed result. Use Clang's <code>-fsyntax-only</code> option to parse C++ |
| programs.</dd> |
| |
| <dt>AST</dt> |
| <dd>Clang builds an abstract syntax tree (AST) for the feature, but does not |
| necessarily perform any type-checking. Use Clang's <code>-ast-print</code> |
| option to print the resulting ASTs.</dd> |
| |
| <dt>Sema</dt> |
| <dd>Clang parses and type-checks this feature and provides a well-formed AST |
| annotated with types. Use Clang's <code>-fsyntax-only</code> to type-check |
| code.</dd> |
| |
| <dt>CodeGen</dt> |
| <dd>Clang parses, type-checks, and generates code for this feature, allowing |
| one to compile and execute programs.</dd> |
| </dl> |
| |
| <p>Updates to this table are welcome! Tests for the various features are also |
| welcome!</p> |
