looks good overall. Added some minor comments.

why do we need change here? Isn't this just for base instructions?

This function is checking that a node is a mask. If this node is AND/AND_NOT/OR/XOR and both of it's children are masks, then it is also a mask. OR_NOT/XOR_NOT also fit into that pattern. I don't think any hwintrinsics today are going to end up there, but we do have predicate OR_NOT/XOR_NOT for SVE, so I think we might end up using it later.

can you add one example for int version?

i meant in addition to uint, add a new test for int. Same for Orn.

Please resolve the merge conflict and then we should be good to go. |
