[PATCH v2 13/14] kbuild: Turn a couple more of clang's unused option warnings into errors

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently, these warnings are hidden with -Qunused-arguments in
KBUILD_CPPFLAGS. Once that option is removed, these warnings should be
turned into hard errors to make unconditionally added but unsupported
flags for the current compilation mode or target obvious due to a failed
build; otherwise, the warnings might just be ignored if the build log is
not checked.
