Clang does not support the /* fall through */ comments. There seems # to be a general consensus in the LLVM community that this is not # something they want to support. Joe Perches wrote a script to convert # all of the comments to a "fallthrough" keyword that will be added to # compiler_attributes.h [2] [3], which catches the vast majority of the # comments. There doesn't appear to be any consensus in the kernel # community when to do this conversion. # # 2. Clang and GCC disagree about falling through to final case statements # with no content or cases that simply break: # # https://godbolt.org/z/c8csDu # # This difference contributes at least 50 warnings in an allyesconfig # build for x86, not considering other architectures. This difference # will need to be discussed to see which compiler is right [4] [5]. # # [1]: https://github.com/llvm/llvm-project/commit/1e0affb6e564b7361b0aadb38805f26deff4ecfc # [2]: https://lore.kernel.org/lkml/61ddbb86d5e68a15e24ccb06d9b399bbf5ce2da7.camel@perches.com/ # [3]: https://lore.kernel.org/lkml/1d2830aadbe9d8151728a7df5b88528fc72a0095.1564549413.git.joe@perches.com/ # [4]: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=91432 # [5]: https://github.com/ClangBuiltLinux/linux/issues/636 # # Given these two problems need discussion and coordination, do not enable # -Wimplicit-fallthrough with clang right now.
