@bcardosolopes Hello, I have dealt with conflict, and in the next pr, I will add cir.sqrt, cir.fabs, cif.floor, cir.ceil lowering mlir passes together |

May I suggest to introduce a template for the 1:1 lowerings from cir to math ops instead? Here, it would just be used by the existing cos and new sin pattern, but looking at #592, the boilerplate duplication would become quite significant otherwise.

Yes, you are right, we can use a template for the 1:1 lowerings from cir to mlir math ops, and we can also use the same template for the 1:1 lowerings from cir to llvm math ops. But the cir.rint cir.shift ops cannot use template, these ops should use the old way.

Instead of using templates I'd rather leverage tablegen to do these. There's a similar idea introduced for LLVM lowering in #434 we could leverage, once that lands (I might commander that PR soon, but happy to let someone else take it) we could do similar for MLIR lowering.
