R. Silva # Date: Mon Sep 13 16:45:28 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. # # 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 # # Link: https://github.com/KSPP/linux/issues/115 # Link: https://github.com/ClangBuiltLinux/linux/issues/236 # [The conditional "ifneq" was idea of Nathan] # Suggested-by: Nathan Chancellor # Reviewed-by: Nathan Chancellor # Tested-by: Nathan Chancellor # Co-developed-by: Kees Cook # Signed-off-by: Kees Cook # Signed-off-by: Gustavo A.
