[LLVMdev] Basic Block / CFG Deep Copy?

Does LLVM offer any way of obtaining a deep copy of a CFG, that is all the
basic blocks of a function and their instructions.

I'm asking because I would like to implement continuations in my VM and I
need to create a modified version of some functions. I thought a simple way
of doing this would be to modify a copy of the code generated for the
orignal function. This would be simpler than modifying all my VM logic to
generate a brand new CFG (and less time consuming).
