The patchset requires the following kbuild change: https://lkml.org/lkml/2018/3/19/1756 With that patch and this patchset applied and I can successfully build the multi_v7_defconfig with 4.16-rc5 using clang 5.0.1. So far I mainly tested with ARMv7 architectures. A brief test with ARMv6 enabled (multi platform configuraiton) failed with an error from the assembler: /tmp/empty-96a4d6.s: Assembler messages: /tmp/empty-96a4d6.s:4: Error: unknown cpu `arm1176j-s' It seems that clang emits a non-existig cpu name: https://reviews.llvm.org/D18086 Stefan Agner (5): bus: arm-cci: use asm unreachable efi/libstub/arm: add support for building with clang ARM: trusted_foundations: do not use naked function ARM: drop no-thumb-interwork in EABI mode ARM: add support for building ARM kernel with clang arch/arm/Makefile | 4 ++-- arch/arm/boot/compressed/Makefile | 2 +- arch/arm/firmware/trusted_foundations.c | 12 +++++++----- drivers/bus/arm-cci.c | 3 +-- drivers/firmware/efi/libstub/Makefile | 3 ++- 5 files changed, 13 insertions(+), 11 deletions(-) -- 2.16.2
