for function 'output_cps_defines'
Hi Paul,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: fe91c4725aeed35023ba4f7a1e1adfebb6878c23
commit: c434b9f80b0923e6460031b0fd964f8b0bf3c6a6 MIPS: Kconfig: add MIPS_GENERIC_KERNEL symbol
date: 1 year, 2 months ago
config: mips-randconfig-r036-20211020 (attached as .config)
compiler: clang version 14.0.0 (https://github.com/llvm/llvm-project 9660563950aaed54020bfdf0be07e7096a9553e4)
reproduce (this is a W=1 build):
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# install mips cross compiling tool for clang build
# apt-get install binutils-mips-linux-gnu

git remote add linus https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
git fetch --no-tags linus master
git checkout c434b9f80b0923e6460031b0fd964f8b0bf3c6a6
