Hi, It wasn't clear from your email exactly what you are doing or what the error was you encountered (grepping in the gollvm/LLVM sources didn't turn up any error code similar to "unable to locate ParamAttr enum"), but I think it is safe to say that this isn't a supported use case for gollvm, at least I don't know of anyone who is doing this sort of thing already.
Generating a *.ll IR file for each translation unit and then reading them all together sounds difficult, seems as though you would need some sort of very strong type unification in order to match up types that are common/shared among translation units. Have you tried doing this on C code, for example?
