Subject: [PATCH AUTOSEL 4.9 13/22] selftests: Set CC to clang in lib.mk if LLVM is set
Date: Wed,  5 May 2021 12:41:20 -0400	[thread overview]
Message-ID: <20210505164129.3464277-13-sashal@kernel.org> (raw)
In-Reply-To: <20210505164129.3464277-1-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.
