Hi Erez,
Thank you for the patch! Yet something to improve:
Thanks for the robot,
as we rarely use clang for kernel. It is very helpful.

base: b65054597872ce3aefbc6a666385eabdf9e288da
config: mips-randconfig-r026-20201209 (attached as .config)
compiler: clang version 12.0.0 (https://github.com/llvm/llvm-project
1968804ac726e7674d5de22bc2204b45857da344)
However the clang in
https://download.01.org/0day-ci/cross-package/clang-latest/clang.tar.xz is
version 11
Sorry that these are issues at our side, including the branch/commit missing.
The push to download.01.org failed and did not really work, we will look for
recovering them.
reproduce (this is a W=1 build):
wget
https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O
~/bin/make.cross
Your make cross script tries to download the clang every time.
Please separate the download (which is ~400 MB and 2 GB after open) from the
compilation.
Hi Erez, thanks for your feedback, we will improve the reproduction
side per these suggestions.
Please use "wget" follow your own instructions in this email.
chmod +x ~/bin/make.cross
# install mips cross compiling tool for clang build
# apt-get install binutils-mips-linux-gnu

I use Debian 10.7.
I usually compile with GCC. I have not see any errors.
When I use clang 11 from download.01.org I get a crash right away.
Please add a proper instructions how to use clang on Debian or provide
a Docker container with updated clang for testing.
If you fix the issue, kindly add following tag as appropriate

Please improve the robot, so we can comply and properly support clang
compilation.
Got it, we will keep improving the bot.
Thanks
