The point of yaml2obj is to be able to generate these invalid objects. In many other cases , you can specify both `Field: SOME_ENUM` and `Field: 42`. I think you  usually have to add a line like this: https://github.com/llvm/llvm-project/blob/4f62a183d9101a90d62e2a278d0513e9d2afba43/llvm/lib/ObjectYAML/ELFYAML.cpp#L55
