Contrary to GCC, # Clang doesn't recognize any comments as implicit fall-through markings # when the -Wimplicit-fallthrough option is enabled. # # So, in order to avoid having more comments being introduced, we use # the option -Wimplicit-fallthrough=5 for GCC, which similar to Clang, # will cause a warning in case a code comment is intended to be used as # a fall-through marking. The patch for Makefile also enforces this. # # We had almost 4,000 of these issues for Clang in the beginning, and # there might be a couple more out there when building some # architectures with certain configurations. However, with the recent # fixes I think we are in good shape and it is now possible to enable # the warning for Clang" # # * tag 'Wimplicit-fallthrough-clang-5.14-rc2' of
