-

-<p>

-This is a bare bones web page for the "clang" C front-end.  This project will

-provide a new C/C++/ObjC front-end for <a href="http://llvm.org">LLVM</a>.

-</p>

-

-<p>The motivation for this project is described well in Steve Naroff's talk

-at the <a href="http://llvm.org/devmtg/2007-05/">2007 LLVM Developer Meeting</a>.

-A <a href="http://llvm.org/devmtg/2007-05/09-Naroff-CFE.mov">video</a> and 

-<a href="http://llvm.org/devmtg/2007-05/09-Naroff-CFE.pdf">slides</a> are 

-available.</p>

-

-<p>Some more motivation, details, and performance numbers are in the second

-half of Chris' <a 

-href="http://llvm.org/pubs/2007-07-25-LLVM-2.0-and-Beyond.html"> LLVM 2.0 

-and Beyond!</a> talk, which describes how the clang pre-processor can be used

-to make distcc 3-4x more scalable.</p>

-<p>Please note that we don't consider this to be ready for people to take and

-compile random pieces of code with yet.  However, if you'd like to do so 

-<em>and</em> help fix problems exposed by doing so, we would appreciate the help.</p>

+		<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.
