>On a side note, one of the dangers of MLIR as far as I can see is an unfortunate side effect that optimisations performed on the language IR will not be available to other languages which use either LLVM IR or their or MLIR variant. This will either mean there are lost optimisation opportunities, or duplicate effort to port passes to other MLIR variants. That'll be a shame. If that's a problem then isn't currently also a issue with the other MLIR variants? I also wonder if LLVM couldn't reduce the need for a language fork of MLIR somehow.
