By emitting the legacy variant of the LLVM IR alongside the newer representation of the attribute, backwards compatibility with any existing BE implementation is restored. A smooth transition period is thus achieved for the aforementiond BE - until it's able to consume the new LLVM IR, it has an option to simply ignore the unknown metadata.

Yep, the Translator retains support for both IR variants, translating these into varying SPIR-V constructs. |
