Hi Nathan,
First bad commit (maybe != root cause):
tree: https://android.googlesource.com/kernel/common android-4.19-r
head: f0719dcb3a6ebfd657bff0df566e70f6fd18e3c9
commit: f0719dcb3a6ebfd657bff0df566e70f6fd18e3c9 [1/1] BACKPORT: ARM: 8900/1: UNWINDER_FRAME_POINTER implementation for Clang
config: arm-randconfig-r005-20210512 (attached as .config)
compiler: clang version 13.0.0 (https://github.com/llvm/llvm-project a0fed635fe1701470062495a6ffee1c608f3f1bc)
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 arm cross compiling tool for clang build
# apt-get install binutils-arm-linux-gnueabi
git remote add android-common https://android.googlesource.com/kernel/common
git fetch --no-tags android-common android-4.19-r
git checkout f0719dcb3a6ebfd657bff0df566e70f6fd18e3c9
# save the attached .config to linux build tree
COMPILER_INSTALL_PATH=$HOME/0day COMPILER=clang make.cross W=1 ARCH=arm
If you fix the issue, kindly add following tag as appropriate
