How to add new attributes to existing Ops?

MLIR
#1

I want to add rounding modifiers to arith::Addf. Is that possible to extend existing Ops? Or do I need to implement my own Addf?

You can attach arbitrary attributes to arbitrary ops using Operation::setAttr, but transformations are not required to preserve or take into account such attributes. Alternatively, you can modify the op itself or indeed create a new op.
