Subject: [PATCH 1/9] Kbuild: only pass -fno-inline-functions-called-once for gcc
Date: Fri, 11 Aug 2023 16:03:19 +0200 [thread overview]
Message-ID: <20230811140327.3754597-2-arnd@kernel.org> (raw)
In-Reply-To: <20230811140327.3754597-1-arnd@kernel.org>
From: Arnd Bergmann <arnd@arndb.de>
clang ignores the -fno-inline-functions-called-once option, but warns
when building with -Wignored-optimization-argument enabled:
clang: error: optimization flag '-fno-inline-functions-called-once' is not supported [-Werror,-Wignored-optimization-argument]
Move it back to using cc-option for this one.
Fixes: 7d73c3e9c514 ("Makefile: remove stale cc-option checks")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
