Subject: [PATCH 4.4 11/70] kbuild: drop -Wno-unknown-warning-option from clang options
Date: Mon, 26 Nov 2018 11:50:26 +0100 [thread overview]
Message-ID: <20181126105047.977564621@linuxfoundation.org> (raw)
In-Reply-To: <20181126105046.722096341@linuxfoundation.org>
4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Masahiro Yamada <yamada.masahiro@socionext.com>
commit a0ae981eba8f07dbc74bce38fd3a462b69a5bc8e upstream.
Since commit c3f0d0bc5b01 ("kbuild, LLVMLinux: Add -Werror to
cc-option to support clang"), cc-option and friends work nicely
for clang.
However, -Wno-unknown-warning-option makes clang happy with any
unknown warning options even if -Werror is specified.
Once -Wno-unknown-warning-option is added, any succeeding call of
cc-disable-warning is evaluated positive, then unknown warning
options are accepted. This should be dropped.
