@ -98,7 +98,29 @@ generation support is far enough along to build many C applications. While not
yet production quality, it is progressing very nicely. In addition, C++
front-end work has started to make significant progress.</p>
<p>Codegen progress/state [DANIEL]</p>
Clang, in conjunction with the <tt>ccc</tt> driver, is now usable as a
replacement for gcc for building some small- to medium-sized C applications.
Additionally, Clang now has code generation support for Objective-C on Mac OS X
platform. Major highlights include:
<ul>
<li> Clang/ccc pass almost all of the LLVM test suite on Mac OS X and Linux
on the 32-bit x86 architecture. This includes significant C
applications such as <a href="http://www.sqlite.org">sqlite3</a>,
<a href="http://www.lua.org">lua</a>, and
<a href="http://www.clamav.net">Clam AntiVirus</a>.
<li> Clang can build the majority of Objective-C examples shipped with the
Mac OS X Developer Tools.
</ul>
Clang code generation still needs considerable testing and development, however.
Some areas under active development include:
<ul>
<li> Improved support for C and Objective-C features, for example
variable-length arries, va_arg, exception handling (Obj-C), and garbage
collection (Obj-C).
<li> ABI compatibility, especially for platforms other than 32-bit x86.
</ul>
