I saw:

These will need to be kept in sync for a given target, but this is already true for most of the values in Clang's TargetInfo.

You can add a consistency check for this in: https://github.com/llvm/llvm-project/blob/c83ebf19cf3e649ed4d2ccadddd8c7e447850363/clang/lib/CodeGen/CodeGenModule.cpp#L338
