llvm dev - May 2010 - [LLVMdev] How to copy a Function

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.

CloneFunction() may do what you want. See:
llvm/include/llvm/Transforms/Utils/Cloning.h
