| Subject: selftests: Set CC to clang in lib.mk if LLVM is set |
| |
| 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. |
