</div>Is this a known problem ? Can you please file a bugzilla ? LLVM should be able to compiler MySQL …<br>
<div class="im"><br></div></blockquote><div style>OK. I didn't find much on the internet related to the clang compilation error. Just filed the bug report <a href="http://llvm.org/bugs/show_bug.cgi?id=15206">http://llvm.org/bugs/show_bug.cgi?id=15206</a></div>

<br>
</div>Look at tools/opt/opt.cpp or tools/llc/llc.cpp. They both initialize the target machine using the target data.<br>
