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_IAS=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 Chancellor <natechancellor@gmail.com> # build # Tested-by: Nick Desaulniers <ndesaulniers@google.com> # Reviewed-by: Nick Desaulniers <ndesaulniers@google.com> # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 a0d1c951ef08ed24f35129267e3595d86f57f5d3 # < make -s -j 48 ARCH=powerpc O=/kisskb/build/kbuild_44x_fsp2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/fsp2_defconfig # < make -s -j 48 ARCH=powerpc O=/kisskb/build/kbuild_44x_fsp2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/kbuild_44x_fsp2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/kbuild_44x_fsp2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x99945c) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xa00000) Image Name: Linux-5.6.0-ga0d1c951ef08 Created: Thu Apr 9 05:51:01 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 4313111 Bytes = 4212.02 KiB = 4.11 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/kbuild_44x_fsp2_defconfig_powerpc-gcc5 # Build took: 0:01:19.779280
