I'm using git worktree command [1] for that.
If it helps, this is snippet from my scripts:
-----------------------------------------
REPORT_FILE=$(mktemp)
function do_one {
SHA1=$1
REPORT_FILE=$2
PDIR=$(mktemp -d)
git worktree add $PDIR $SHA1
echo "Redirecting the output to $REPORT_FILE"
pushd $PDIR &>> $REPORT_FILE
x checkpatch HEAD $PDIR &>> $REPORT_FILE
cp $KCONFIG . &>> $REPORT_FILE
make olddefconfig &>> $REPORT_FILE
echo "===== FULL COMPILE =========" &>> $REPORT_FILE
make -s -j 4 &>> $REPORT_FILE
echo "===== SUB COMPILE =========" &>> $REPORT_FILE
make -s -j 4 W=1 drivers/infiniband/ drivers/net/ethernet/mellanox/ &>> $REPORT_FILE
echo "===== SMATCH =========" &>> $REPORT_FILE
make CHECK="$SMATCH -p=kernel" C=1 drivers/infiniband/ drivers/net/ethernet/mellanox/ -s -j 4 &>> $REPORT_FILE
echo "===== SPARSE =========" &>> $REPORT_FILE
make CHECK="$SPARSE" C=2 drivers/infiniband/ drivers/net/ethernet/mellanox/ -s -j 4 &>> $REPORT_FILE
popd &>> $REPORT_FILE
rm -rf $PDIR
git worktree prune
# TODO: separate checkpatch errors, sparse, smatch
NUMB_OF_ERRORS=$(awk -F": " '{print $1}' $REPORT_FILE | grep ":" | sort | uniq |wc -l)
echo "There are $NUMB_OF_ERRORS errors/warnings"
}
do_one $SHA1 $REPORT_FILE
------------------------------------------
Thanks
