##并发克隆git库
for i in $modules
do
{
	echo "git clone $i"
	git clone $i
}
done
wait
echo "finish clone!"

##调整目录层次
mv -f ./clang ./llvm/tools/
mv -f ./clang-tools-extra ./llvm/tools/clang/tools/
#mv -f ./lldb ./llvm/projects/
#mv -f ./dragonegg ./llvm/projects/
mv -f ./libcxx ./llvm/projects/
mv -f ./compiler-rt ./llvm/projects/
