Nice.
An alternative would be to do a 4-step process of:
- Create the new
FirMemReadOp(notreplaceOpWithNewOp). - Copy over the attributes.
- RAUW
- Erase the old op.
The cost of the temporary is basically free here as these temporaries are ArrayRef<NamedAttribute> and ArrayRef<StringRef>. I think that this is safe as everything backing those refs should be in interned storage. However, I'm not totally sure.

Awesome! Thanks a lot for the quick fix 💯. Totally missed that during testing 🤔 |
