it's surely just that dragonegg doesn't have any support for this builtin.<br></blockquote><div> </div><div>ok.

I am stuck on analysis. Does any one have alternate suggestions on debugging<br>
llvm? (Please refer to comments for the work done so far)<br>
<br>
<br>
try to reduce a small standalone testcase which is an LLVM IR (.ll) file.<br>
