These were ignored by git accidentally. We want ALL OF THEM since they all came in the llvm/clang source distribution.

<h1>clang: a C language family frontend for LLVM</h1>
|
|
<!--*********************************************************************-->
|
|
|
|
<p>The goal of the Clang project is to create a new C, C++, Objective C and
|
|
Objective C++ front-end for the <a href="http://www.llvm.org/">LLVM</a>
|
|
compiler. You can <a href="get_started.html">get and build</a> the source
|
|
today.</p>
|
|
|
|
<!--=====================================================================-->
|
|
<h2 id="goals">Features and Goals</h2>
|
|
<!--=====================================================================-->
|
|
|
|
<p>Some of the goals for the project include the following:</p>
|
|
|
|
<p><b><a href="features.html#enduser">End-User Features</a></b>:</p>
|
|
|
|
<ul>
|
|
<li>Fast compiles and low memory use</li>
|
|
<li>Expressive diagnostics (<a href="diagnostics.html">examples</a>)</li>
|
|
<li>GCC compatibility</li>
|
|
</ul>
|
|
|
|
<p><b><a href="features.html#applications">Utility and
|
|
Applications</a></b>:</p>
|
|
|
|
<ul>
|
|
<li>Modular library based architecture</li>
|
|
<li>Support diverse clients (refactoring, static analysis, code generation,
|
|
etc)</li>
|
|
<li>Allow tight integration with IDEs</li>
|
|
<li>Use the LLVM 'BSD' License</li>
|
|
</ul>
|
|
|
|
<p><b><a href="features.html#design">Internal Design and
|
|
Implementation</a></b>:</p>
|
|
|
|
<ul>
|
|
<li>A real-world, production quality compiler</li>
|
|
<li>A simple and hackable code base</li>
|
|
<li>A single unified parser for C, Objective C, C++, and Objective C++</li>
|
|
<li>Conformance with C/C++/ObjC and their variants</li>
|
|
</ul>
|
|
|
|
<p>Of course this is only a rough outline of the goals and features of
|
|
Clang. To get a true sense of what it is all about, see the <a
|
|
href="features.html">Features</a> section, which breaks
|
|
each of these down and explains them in more detail.</p>
|
|
|
|
|
|
<!--=====================================================================-->
|
|
<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
|
|
nimble compiler that is easy to develop and maintain. All of these were
|
|
motivations for starting work on a new front-end that could
|
|
meet these needs.</p>
|
|
|
|
<p>A good (but quite dated) introduction to Clang can be found in the
|
|
following video lectures:</p>
|
|
|
|
<ul>
|
|
<li><a href="clang_video-05-25-2007.html">Clang Introduction</a>
|
|
(May 2007)</li>
|
|
<li><a href="clang_video-07-25-2007.html">Features and Performance of
|
|
Clang</a> (July 2007)</li>
|
|
</ul>
|
|
|
|
<p>For a more detailed comparison between Clang and other compilers, please
|

|
<h2>Current Status</h2>
|
|
<!--=====================================================================-->
|
|
|
|
<p>Clang is still under heavy development. Clang is considered to
|
|
be a production quality C, Objective-C, C++ and Objective-C++ compiler when
|
|
targeting X86-32, X86-64, and ARM (other targets may have caveats, but are
|
|
usually easy to fix). If you are looking for source analysis or
|
|
source-to-source transformation tools, clang is probably a great
|
|
solution for you. Clang supports most of C++11, please see the <a
|
|
href="cxx_status.html">C++ status</a> page for more
|
|
information.</p>

<h2>Get it and get involved!</h2>
|
|
<!--=====================================================================-->
|
|
|
|
<p>Start by <a href="get_started.html">getting the code, building it, and
|
|
playing with it</a>. This will show you the sorts of things we can do
|
|
today and will let you have the "clang experience" first hand: hopefully
|
|
it will "resonate" with you. :)</p>
|
|
|
|
<p>Once you've done that, please consider <a href="get_involved.html">getting
|
|
involved in the clang community</a>. The clang developers include numerous
|
|
volunteer contributors with a variety of backgrounds. If you're
|
|
interested in
|
|
following the development of clang, signing up for a mailing list is a good
|
|
way to learn about how the project works.</p>
