Derived attributes are attributes that are not stored in the Op but instead computed from properties of the op (https://mlir.llvm.org/docs/OpDefinitions/#operation-arguments). E.g., a derived attribute T corresponding to the result type results in a convenience accessor T() that returns the result type but is not additionally stored. This allows for convenience functions that query the op (and return the result in convenient user usable format) without needing to store redundant information.
