commit: 670d0a4b10704667765f7d18f7592993d02783aa sparse: use identifiers to define address spaces
date: 5 weeks ago
config: openrisc-randconfig-s032-20200725 (attached as .config)
compiler: or1k-linux-gcc (GCC) 9.3.0
reproduce:
wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross
chmod +x ~/bin/make.cross
# apt-get install sparse
# sparse version: v0.6.2-93-g4c6cbe55-dirty
git checkout 670d0a4b10704667765f7d18f7592993d02783aa
