@silee2 Can you elaborate a bit what you want done here? In refactor the cmake/modules introduces clones of the MLIR macros with an IMEX prefix. The reason I did this was to make it easier to distill IMEX-specific passes, libraries, etc and make. Do you want to revert back to MLIR-specific macros? If so, can you please elaborate why?
