That won't always work, because some of our kernel APIs are defined as macros, and I don't think it's a trivial job to generate a macro definition to a function definition so that it can be translated to something in IR. We will have to do the macro -> function mapping ourselves somewhere, if we want to inline the API across languages. Regards, Boqun
