Okay, I understand. Considering that swifterror is a generic LLVM IR feature I think it should be discussed in the documentation [1]. I will create a documentation PR with some of the above info on swifterror.

I think swifterror is related to the intrinsics coro.alloca.alloc, coro.alloca.get and coro.alloca.free but these are also not described in [1]. Can you comment on their connection?
