  36 <p>Clang currently implements all of the ISO C++ 1998 standard (including
  37   the defects addressed in the ISO C++ 2003 standard) except for 'export'
  38   (which has been removed from the C++'0x draft).
  39   The <a href="http://llvm.org/bugs/">LLVM bug tracker</a>
  40   contains a Clang C++ component that tracks known Clang C++ bugs.</p>
  41
  42  <h2 id="projects">Projects Building with Clang</h2>
  43
  44   <p>Clang is now capable of compiling large C++ projects, and the following
  45    table describes various projects that we have attempted to compile with
  46    Clang++.</p>

  83
  84 <p>Clang's development effort is focused primarily on fixing bugs in the current
  85 ISO C++ standard (1998/2003). This section tracks the status of various C++0x
  86 features.</p>
  87
  88 <p>You can use clang in C++0x mode either
  89 with <a href="http://libcxx.llvm.org/">libc++</a> or with gcc's libstdc++.
  90 libstdc++-4.4 requires <a href="libstdc++4.4-clang0x.patch">a patch</a> to work
  91 with clang; other versions have not been tested.</p>

 140 <p>In addition, boxes marked with &#x2713 have complete and passing tests.
 141   Similarly, boxes marked with &#x2717 have complete tests, some of which
 142   are failing, and a <b>?</b> indicates partial tests while not making any
 143   statement about passing status.</p>
 144
 145 <p>A feature is "complete" when the appropriate Clang component (Parse, AST,
 146 Sema, CodeGen) implements the behavior described in all of the
 147 paragraphs in the relevant C++'0x draft standard.  The major
 148 components are:</p>
 149
 150 <dl>
 151   <dt>Parse</dt>
 152   <dd>Clang is able to parse the grammar of this feature (or the grammar
 153    described by this section), but does not necessarily do anything with the
 154    parsed result. Use Clang's <code>-fsyntax-only</code> option to parse C++
 155     programs.</dd>
 156
 157   <dt>AST</dt>
 158   <dd>Clang builds an abstract syntax tree (AST) for the feature, but does not
 159   necessarily perform any type-checking. Use Clang's <code>-ast-print</code>
 160   option to print the resulting ASTs.</dd>
 161
 162   <dt>Sema</dt>
 163   <dd>Clang parses and type-checks this feature and provides a well-formed AST
 164     annotated with types. Use Clang's <code>-fsyntax-only</code> to type-check
 165      code.</dd>
 166
 167   <dt>CodeGen</dt>
 168   <dd>Clang parses, type-checks, and generates code for this feature, allowing
 169    one to compile and execute programs.</dd>
 170 </dl>
 171

 173 welcome!</p>
