> I should note that the IR that describes an indirect call to a returns twice function will not be generated by current clang. It seems like the SROA pass drops that attribute when it replaces the value. Perhaps it did at one point do that, as I don't think I hand wrote the IR. I will see if that is a bug or not.

Filed https://github.com/llvm/llvm-project/issues/60732. It is a generic issue with SROA I think.
