@celinval do you know why this intrinsic is handled separately rather than in the big match with all the others?

Can this test use core::intrinsics instead?
Edit: Nope, that would invalidate the test. It seems like it could use a different intrinsic though.
Edit2: This test was added in 22e3a85

Yeah I don't know what this is testing so I changed it as little as possible...

Uh, how could this PR possibly break that incremental test... ( |
|
I don't really know much about incremental 🙏 Hope you manage to figure it out |
|
I can look later if you are willing to wait a day or so 🤔 |
|
The PR is blocked on some other stuff anyway. |
|
This isn't an incremental bug per se, but instead a bug that has to do with debug printing query keys when debug assertions and I've pushed a commit which should fix this. |
