Subject: [PATCH 1/3] kbuild: add -Wno-pointer-sign flag unconditionally
Date: Mon, 1 Oct 2018 18:44:36 +0900 [thread overview]
Message-ID: <1538387078-21892-1-git-send-email-yamada.masahiro@socionext.com> (raw)
We have raised the compiler requirement from time to time.
With commit cafa0010cd51 ("Raise the minimum required gcc version
to 4.6"), the minimum for GCC is 4.6 now.
The -Wno-pointer-sign has been here since the pre-git era. It is
documented in the GCC 4.6 manual, and it is recognized by Clang
and ICC as well.
Let's rip off the cc-disable-warning switch, and see if somebody
complains about it.
