<h4 id="c11changes">C11 Feature Support</h4>

<p>...</p>

<p>Clang 3.2 adds support for the C11 <code>_Alignof</code> keyword, pedantic warning through option

       <code>-Wempty-translation-unit</code> (C11 6.9p1) </p>

<h4 id="cxx11changes">C++11 Feature Support</h4>

<p>...</p>

<p>Clang 3.2 supports <a href="http://clang.llvm.org/cxx_status.html#cxx11">most of the language features</a> 

       added in the latest ISO C++ standard,<a href="http://www.iso.org/iso/iso_catalogue/catalogue_tc/catalogue_detail.htm?csnumber=50372">C++ 2011</a>.

       Use <code>-std=c++11</code> or <code>-std=gnu++11</code> to enable support for these features. In addition to the features supported by Clang 3.1, the

       following features have been added:</p>

<ul>

 <li>Implemented the C++11 discarded value expression rules for volatile lvalues.</li>

 <li>Support for the C++11 enum forward declarations.</li>

 <li>Handling of C++11 attribute namespaces (automatically).</li>

 <li>Implemented C++11 [conv.prom]p4: an enumeration with a fixed underlying type has integral promotions 

         to both its underlying type and to its underlying type's promoted type.</li>

</ul>

<p>These are major API changes that have happened since the 3.1 release of

   Clang. If upgrading an external codebase that uses Clang as a library, this

   section should help get you past the largest hurdles of upgrading.</p>

This is just a section to hold things that have already gotten started and

should likely pick up proper release notes in 3.1.

- C1X and C++11 atomics infrastructure and support

- CUDA support?
