it's surely just that dragonegg doesn't have any support for this builtin.<br>
<br>
ok. Just verified that Target.cpp and x86_builtins do not have iceil support.<br>
I have this tricky situation - I use dragonegg generated LLVM IR as input to<br>
clang for some analysis (well it is clang++ actually). Understably,clang cribs<br>
looking at __builtin_iceil. Any idea how to resolve that as well?<br>

adding dragonegg support for iceil would solve both problems.<br></blockquote><div> </div><div>Cool. <a href="http://llvm.org/bugs/show_bug.cgi?id=14270">http://llvm.org/bugs/show_bug.cgi?id=14270</a></div><div> </div><div>

I am stuck on analysis. Does any one have alternate suggestions<br>
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)<br>
file.<br>
<br>
Ciao, Duncan.<br>
