Hi, Thank you so much for the tutorial series. It is really great and helped me a lot to understand a few core concepts of MLIR framework.

I was wondering if you can also include a tutorial where you show the way to build the passes as standalone shared library and show the process to call load the dialect and the pass library from command line using mlir-opt. I think this would be a great addition to the already great tutorial series.

Thanks in advance.

I was not aware this is possible. Where did you hear about it?

Hi. Thank you for the response. Here is the way it works in LLVM :

opt -load <shared-lib-of-some-pass.so> --<name-of-the-pass-registered-in-passmanager> <other-options> <input-ir-file>

Here is what was proposed similar for MLIR:

https://discourse.llvm.org/t/rfc-load-pass-plugin-for-mlir-opt/65049

Here is what I see when I run mlir-opt --help | grep plugin.

So I thought that this functionality may have been added. But I can not find any code example or documentation of this feature.

I built MLIR from source based on this commit: 28b27c1b10ae8d1f5b4fb9df691e8cf0da9be3f6
