@ -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>
