  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>

 103 <p>The following table is used to help track our implementation

 135 <p>In addition, boxes marked with &#x2713 have complete and passing tests.
 136   Similarly, boxes marked with &#x2717 have complete tests, some of which
 137   are failing, and a <b>?</b> indicates partial tests while not making any
 138   statement about passing status.</p>
 139
 140 <p>A feature is "complete" when the appropriate Clang component (Parse, AST,
 141 Sema, CodeGen) implements the behavior described in all of the
 142 paragraphs in the relevant C++'0x draft standard.  The major
 143 components are:</p>
 144
 145 <dl>
 146   <dt>Parse</dt>
 147   <dd>Clang is able to parse the grammar of this feature (or the grammar
 148    described by this section), but does not necessarily do anything with the
 149    parsed result. Use Clang's <code>-fsyntax-only</code> option to parse C++
 150     programs.</dd>
 151
 152   <dt>AST</dt>
 153   <dd>Clang builds an abstract syntax tree (AST) for the feature, but does not
 154   necessarily perform any type-checking. Use Clang's <code>-ast-print</code>
 155   option to print the resulting ASTs.</dd>
 156
 157   <dt>Sema</dt>
 158   <dd>Clang parses and type-checks this feature and provides a well-formed AST
 159     annotated with types. Use Clang's <code>-fsyntax-only</code> to type-check
 160      code.</dd>
 161
 162   <dt>CodeGen</dt>
 163   <dd>Clang parses, type-checks, and generates code for this feature, allowing
 164    one to compile and execute programs.</dd>
 165 </dl>
