R. Silva # Date: Mon Jul 12 00:57:54 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. # # It's important to mention that since we have adopted the use of the # pseudo-keyword macro fallthrough; we also want to avoid having more # /* fall through */ comments being introduced. Notice that 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 have to 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. # # Co-developed-by: Kees Cook # Signed-off-by: Kees Cook # Signed-off-by: Gustavo A.
