I think the LLVM devs presented results of compiling the kernel several years ago. I don't recall the link to the talk, though. I think some of the kernel devs are the biggest problem. Some of the developers feel GCC is the only compiler to support. They rely on GCC-isms, and don't care about things like undefined behavior since it "works for me using GCC." I've even had some of the devs tell me they don't care about the C standard. That was very befuddling to me.
