Enable -Wimplicit-fallthrough for Clang" # # This reverts commit b7eb335e26a9c7f258c96b3962c283c379d3ede0. # # It turns out that the problem with the clang -Wimplicit-fallthrough # warning is not about the kernel source code, but about clang itself, and # that the warning is unusable until clang fixes its broken ways. # # In particular, when you enable this warning for clang, you not only get # warnings about implicit fallthroughs. You also get this: # # warning: fallthrough annotation in unreachable code [-Wimplicit-fallthrough] # # which is completely broken becasue it # # (a) doesn't even tell you where the problem is (seriously: no line # numbers, no filename, no nothing). # # (b) is fundamentally broken anyway, because there are perfectly valid # reasons to have a fallthrough statement even if it turns out that # it can perhaps not be reached. # # In the kernel, an example of that second case is code in the scheduler: # # switch (state) { # case cpuset: # if (IS_ENABLED(CONFIG_CPUSETS)) { # cpuset_cpus_allowed_fallback(p); # state = possible; # break; # } # fallthrough; # case possible: # # where if CONFIG_CPUSETS is enabled you actually never hit the # fallthrough case at all. But that in no way makes the fallthrough # wrong. # # So the warning is completely broken, and enabling it for clang is a very # bad idea. # # In the meantime, we can keep the gcc option enabled, and make the gcc # build use # # -Wimplicit-fallthrough=5 # # which means that we will at least continue to require a proper # fallthrough statement, and that gcc won't silently accept the magic # comment versions. Because gcc does this all correctly, and while the odd # "=5" part is kind of obscure, it's documented in [1]: # # "-Wimplicit-fallthrough=5 doesn’t recognize any comments as # fallthrough comments, only attributes disable the warning" # # so if clang ever fixes its bad behavior we can try enabling it there again. # # Link: https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html [1] # Cc: Kees Cook <keescook@chromium.org> # Cc: Gustavo A.
