    LLVM's license is not a "copyleft" license like the GPL). We suggest that you
    read the <a href="http://www.opensource.org/licenses/UoI-NCSA.php">License</a>

+<p>In addition to the UIUC license, the runtime library components of LLVM
+   (<b>compiler_rt and libc++</b>) are also licensed under the <a
+   href="http://www.opensource.org/licenses/mit-license.php">MIT license</a>,
+   which does not contain the binary redistribution clause.  As a user of these
+   runtime libraries, it means that you can choose to use the code under either
+   license (and thus don't need the binary redistribution clause), and as a
+   contributor to the code that you agree that any contributions to these
+   libraries be licensed under both licenses.  We feel that this is important
+   for runtime libraries, because they are implicitly linked into applications
+   and therefore should not subject those applications to the binary
+   redistribution clause. This also means that it is ok to move code from (e.g.)
+   libc++ to the LLVM core without concern, but that code cannot be moved from
+   the LLVM core to libc++ without the copyright owner's permission.
