The error leads to:
https://github.com/llvm/clangir/blob/eaae025754b5c58f2ede4787d328d79a0a671b94/clang/lib/CIR/CodeGen/CIRGenTypes.cpp#L73-L74
and it leads to:

So it looks like we're going to print the name of type and get the attribute from it. Then I get confused. How can we get the attributes from the name of the type?
