I am currently working on a transformation pass that transforms masked.load and masked.store intrinsics to (hopefully) increase performance on targets where masked.load and masked.store are not legal. To check if the loads and stores are necessary at all I take the mask for the masked operations and want to reduce them to a single value. vector.reduce.or seemed very handy to do the job. I

I assume smaller types like <4 x i1> are getting zero extended to e.g., i8?

Hi Amara, thank you for the clarification. I tested the intrinsics x86_64 and it seemed to work pretty well. Looking forward to try this intrinsics with the AArch64 backend. Maybe I find the time to look into codegen to get this intrinsics out of experimental stage. They seem pretty useful.
