You can pass it from the command line or as an # environment variable. # # Please note LLVM=1 does not turn on the integrated assembler. You need # to pass LLVM_IA=1 to use it. When the upstream kernel is ready for the # integrated assembler, I think we can make it default. # # We discussed what we need, and we agreed to go with a simple boolean # flag that switches both target and host tools: # # https://lkml.org/lkml/2020/3/28/494 # https://lkml.org/lkml/2020/4/3/43 # # Some items discussed, but not adopted: # # - LLVM_DIR # # When multiple versions of LLVM are installed, I just thought supporting # LLVM_DIR=/path/to/my/llvm/bin/ might be useful. # # CC = $(LLVM_DIR)clang # LD = $(LLVM_DIR)ld.lld # ... # # However, we can handle this by modifying PATH. So, we decided to not do # this. # # - LLVM_SUFFIX # # Some distributions (e.g. Debian) package specific versions of LLVM with # naming conventions that use the version as a suffix. # # CC = clang$(LLVM_SUFFIX) # LD = ld.lld(LLVM_SUFFIX) # ... # # will allow a user to pass LLVM_SUFFIX=-11 to use clang-11 etc., # but the suffixed versions in /usr/bin/ are symlinks to binaries in # /usr/lib/llvm-#/bin/, so this can also be handled by PATH. # # Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> # Reviewed-by: Nathan Chancellor <natechancellor@gmail.com> # Tested-by: Nathan
