Subject: [PATCH AUTOSEL 5.12 078/116] selftests: Set CC to clang in lib.mk if LLVM is set
Date: Wed, 5 May 2021 12:30:46 -0400 [thread overview]
Message-ID: <20210505163125.3460440-78-sashal@kernel.org> (raw)
In-Reply-To: <20210505163125.3460440-1-sashal@kernel.org>
From: Yonghong Song <yhs@fb.com>
[ Upstream commit 26e6dd1072763cd5696b75994c03982dde952ad9 ]
selftests/bpf/Makefile includes lib.mk. With the following command
make -j60 LLVM=1 LLVM_IAS=1 <=== compile kernel
make -j60 -C tools/testing/selftests/bpf LLVM=1 LLVM_IAS=1 V=1
some files are still compiled with gcc. This patch
fixed lib.mk issue which sets CC to gcc in all cases.
