How did you select the attributes you want to implement in csmith? It is for example a little strange that you decided to include "pure" but not "const." If you handle visibility, you might as well consider throwing in externally_visible too, I guess. As a stretch goal, the alias function attribute might be useful to exercise nasty paths in GCC IPA optimizations. I assume Andi Kleen has seen this proposal and if he is fine with it, so am I. Thanks, Martin
