tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: c578ddb39e565139897124e74e5a43e56538cb33
commit: e33a814e772cdc36436c8c188d8c42d019fda639 scripts/dtc: Remove redundant YYLOC global declaration
date: 4 weeks ago
config: powerpc-randconfig-a001-20200423 (attached as .config)
compiler: clang version 11.0.0 (https://github.com/llvm/llvm-project bbf386f02b05db017fda66875cc5edef70779244)
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# install powerpc cross compiling tool for clang build
# apt-get install binutils-powerpc-linux-gnu
git checkout e33a814e772cdc36436c8c188d8c42d019fda639
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross ARCH=powerpc
If you fix the issue, kindly add following tag as appropriate
