Re: declaration operations: It could be but I thought that would be so unlikely that it would be better to only make that (minimal) change if it was ever needed.

Re: this thread: Kaviya and I were unable to get it working. It turns out that the MLIR pass manager doesn't allow for arbitrary nesting: only 1 level deep. So you can run a func.func pass on a pass manager for a module because the func.func is a direct descendant. But it couldn't be done for simd because that could be anywhere in the operation tree. Sorry, I should have posted something here.
