I don't think so. The compiler does not warn about a missing fallthrough.

I've uploaded the configs and object files to:
https://tglx.de/~tglx/clang.tar.bz2
contains:
clang/
clang/debian/
clang/debian/atom.o
clang/debian/platform.o
clang/debian/i915_gem_execbuffer.o
clang/debian/.config
clang/debian/evergreen_cs.o
clang/allmod/
clang/allmod/ubsan.o
clang/allmod/i915_gem_execbuffer.o
clang/allmod/.config
clang/allmod/sata_dwc_460ex.o
clang/allmod/common.o
clang/allmod/signal.o
clang/allmod/ia32_signal.o
i.e. the .config and the offending object files for the debian and
allmodconfig builds.
Thanks,
tglx
