Actually, I'm just wrong here, sorry. Looking closer, there actually *is* a mapping between the C enum and C++ enum: https://github.com/llvm/llvm-project/blob/387f3e8f986d53067a68aa0d7b058a0ce81ec941/llvm/lib/IR/DebugInfo.cpp#L1857-L1866 I didn't find it when searching for the constants because it's macro based. So actually everything is good here, and it's okay to add entries to Metadata.def in any order. Sorry again for the confusion!
