commit: 80591e61a0f7e88deaada69844e4a31280c4a38f kbuild: tell sparse about the $ARCH
date: 7 months ago
config: alpha-randconfig-s031-20200619 (attached as .config)
compiler: alpha-linux-gcc (GCC) 9.3.0
reproduce:
# apt-get install sparse
# sparse version: v0.6.2-rc1-18-g27caae40-dirty
git checkout 80591e61a0f7e88deaada69844e4a31280c4a38f
# save the attached .config to linux build tree
make W=1 C=1 ARCH=alpha CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'
