> - As I know LLVM doesn't promise backward comparability so we tried following the correct solution (notice that another way is to suggest 'mayoverflow' attribute but it won't match other attributes in LLVM). Regarding the AutoUpgrade logic I will be glad if you can clarify more on what has to be done?

That is not true, we do provide backward compatibility: https://llvm.org/docs/DeveloperPolicy.html#ir-backwards-compatibility
