FWIW libbcc so many BPF users also use clang, so this has more impact than just testing to build linux with clang (not that this would be any reason to delay fixing either way) I would tend to agree havin a compiler-common + make clang/intel not include compiler-gcc would probably be best in the long run but we might want a quick fix for 4.19 meanwhile.. -- Dominique Martinet
