Subject: [PATCH 0/5] ARM: clang support
Date: Wed, 21 Mar 2018 00:02:01 +0100 [thread overview]
Message-ID: <20180320230206.25289-1-stefan@agner.ch> (raw)
This patchset fixes some remaining issues when building the ARM
architecture using LLVM/clang. 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:
