| <h1>Clang: a C language front-end for LLVM</h1> | ||
| <h2>About</h2> | ||
| <p>The goal of the Clang project is to create a new <a href="http://llvm.org/svn/llvm-project/cfe/trunk/LICENSE.TXT">BSD Licensed</a> C, C++, & ObjC front-end for the <a href="http://www.llvm.org/">LLVM</a> compiler. | ||
| <br><br> | ||
| <p>In the context of this website, the term Clang actually refers to two things: | ||
| <p>1) A "code name" for the LLVM compiler front-end. | ||
| <p>2) A specific library in the LLVM front-end -- in particular the "driver" that makes all the other libraries work together. | ||
| <br><br> | ||
| <p>The developers of Clang include contributers from Apple and numerous other volunteers. | ||
| <h2>Why?</h2> | ||
| <p>The development of a new front-end was started out of a need -- a need for a compiler that allows better diagnostics, better integration with IDEs, a license that is compatible with commercial products, and a compiler that is easier to develop and maintain. All of these were motiviations for starting work on a new C/C++/ObjC front-end that could meet these needs. | ||
| <p>An excellent introduction to Clang can be found in the following video lectures: | ||
| <ul> | ||
| <li><a href="clang_video-05-25-2007.html">Clang Introduction</a> | ||
| <li><a href="clang_video-07-25-2007.html">Features and Performance of Clang</a> | ||
| </ul> | ||
| <h2>Features/Goals</h2> | ||
| Some of the goals for the project include the following: | ||
| <ul> | ||
| <li>Unified parser for C-based languages | ||
| <li>Language conformance with C99, ObjC, C++ | ||
| <li>Real-world, production quality compiler | ||
| <li>GCC compatibility | ||
| <li>Library based architecture with finely crafted C++ API's | ||
| <li>High performance | ||
| <li>Better integration with IDEs | ||
| <li>Expressive diagnostics | ||
| <li>BSD License | ||
| </ul> | ||
| Of course this is only a rough outline of the goals and features of Clang. To get a true sense of what the new LLVM front-end is all about, as well as why you might want to considering using it, see the <a href="features.html">Features</a> section. | ||

| <h2>Features/Goals</h2> | ||
| Some of the goals for the project include the following: | ||

| <li>Real-world, production quality compiler.</li> | ||

| <li>Language conformance with C, ObjC, C++ (including variants, like C90, C99, etc)</li> | ||
| <li>GCC compatibility (supports GCC extensions, but allow them to be disabled)</li> | ||
| <li>Library based architecture with finely crafted C++ API's</li> | ||
| <li>High performance</li> | ||
