[LLVMdev] How to copy a Function

[Jianzhou Zhao]

Hi,

I wanted to backup a Function before it is optimized. The Function
class disallows assignment operations as it comments:
  Function(const Function&); // DO NOT IMPLEMENT
  void operator=(const Function&); // DO NOT IMPLEMENT
Is there a way to construct a copy from an existing Function?

Thanks.
