R. Silva <gustavoars@kernel.org> # Date: Tue Aug 17 15:33:33 2021 -0500 # # Makefile: Enable -Wimplicit-fallthrough for Clang # # With the recent fixes for fallthrough warnings, it is now possible to # enable -Wimplicit-fallthrough for Clang. # # Special thanks to Nathan Chancellor who fixed the Clang bug[1][2] # that put the application of this patch to a halt, temporarily. This # bugfix only appears in Clang 14.0.0, so older versions still contain # the bug and -Wimplicit-fallthrough won't be enabled for them, for # now. # # As Masahiro noted, the "ifeq" conditional "will break when Clang # version 100.0.0 is released. But, before that, we will raise the # minimum supported clang version, and this conditional will go away."[3] # # This concludes a long journey and now we are finally getting rid # of the unintentional fallthrough bug-class in the kernel, entirely. # # [1] https://github.com/llvm/llvm-project/commit/9ed4a94d6451046a51ef393cd62f00710820a7e8 # [2] https://bugs.llvm.org/show_bug.cgi?id=51094 # [3] https://lore.kernel.org/lkml/CAK7LNAQFgYgavTP2ZG9Y16XBVdPuJ98J_Ty1OrQy1GXHq6JjQQ@mail.gmail.com/ # # Link: https://github.com/KSPP/linux/issues/115 # Link: https://github.com/ClangBuiltLinux/linux/issues/236 # ["firstword" and "sort" was idea of Masahiro] # Suggested-by: Masahiro Yamada <masahiroy@kernel.org> # [The conditional "ifeq" was idea of Nathan] # Suggested-by: Nathan Chancellor <nathan@kernel.org> # Reviewed-by: Nathan Chancellor <nathan@kernel.org> # Tested-by: Nathan Chancellor <nathan@kernel.org> # Co-developed-by: Kees Cook <keescook@chromium.org> # Signed-off-by: Kees Cook <keescook@chromium.org> # Signed-off-by: Gustavo A.
