Hi, * I don't know whether this is a correct medium to ask this or not. So, sorry if this is not related. I have many complicated structures of LLVM objects and I want to serialize those information and eventually write it to a file or transport it. To give you an idea I have many objects like std::vectore<LLVM::BranchInst*> and many others. I am trying to figure out what is the best approach to this problem. since I don't want to change every class I am using in LLVM, I prefer a non-intrusive method. The problem with Protobuf and approaches like that is I have to write a structure file for every LLVM object I am using. I am okay with that if I know for sure there is no better option. Besides that, I was thinking about using LLVM objects bitcode representation (if I can kind of like an array of byte for bitcode representation). But I hadn't any luck so far. If I get the bitcode representation of an object I can manage to serialize other stuff. I don't know this is viable or not. Or whether I can get bitcode of an object independently. best wishes, -navid
