...cfe-dev since this seems relevant to Clang, particularly the questions at the end.) I've been working on a library to generate LLVM IR that complies with platform ABIs (the current focus is on C but I'm also interested in ABIs for other languages). You can find it here: https://github.com/scross99/llvm-abi To explain further (for those who are unfamiliar), LLVM frontends have to modify function argument types, attributes etc. in order to ensure the backend generates code that satisfies the ABI; this is needed because LLVM's type system can't encode all the necessary information. Thi...

...actually gets emitted for particular functions. If you stay away from passing structs/unions by value, it becomes a *lot* simpler, though... Some people have tried to make libraries for doing the ABI lowering available in a way that's not tied to clang. Here's one: < https://github.com/scross99/llvm-abi> (I have no idea how well, or if, it works). I think I've also seen mention of someone constructing the proper classes to pass to clang to have it emit the C ABI calls from their non-C language, although I'm not sure where I saw that. Is there any current plan to change the wa...

Thanks for the explanation. It's good to hear the situation isn't felt to be ideal. The details here are going to be sensitive to the OS + target that I'm compiling for, right? So the effort here will be to understand and get right the calling convention details for each supported target, yes? Is there any current plan to change the way this works, or is it more of a dreamy cleanup
