> MLIR didn't even exist when Julia was created. A language that can really take advantage of MLIR, and is designed from the ground up for modern accelerators, is not something that can be readily created by tweaking Julia AFAICT.
MLIR is another level of intermediate representation that sits at a higher level than LLVM-IR. Should the Julia folks decide that MLIR would offer advantages for optimization it wouldn't be difficult for them to add in an MLIR intermediate stage - that's kind of the whole point of an IR. But again, that would take some development effort - if the kind of investment that Mojo was getting were available for Julia it would get done. Nothing about the language itself would need to be impacted, it's the mid and backend where MLIR can offer advantages.
