Clang can't compile the linux kernel (some inline asm not supported) and replaypc (error: use of unknown builtin '__builtin_next_arg'). The concrete results are attached.<br>

</div>Nice, I don't have access to CSiBE. Out of curiosity, why aren't llvm -O2 numbers included? Would you be willing to track down a few examples of things where llvm is generating bigger code and file PRs?<br>
