> I have a feeling this test may now be a bit redundant now with the ISA changes to the target region, CSE should function on both the host and device the same now I would imagine and I believe it'd function like it does on device currently for host and device. I imagine removal is the way to go, but amending both host and device checks to be identical would be another route @skatrak will likely know better, but I believe he is on vacation until sometime next week unfortunately

I agree, this test can be deleted altogether. Since we made `omp.target` `IsolatedFromAbove` a while back it's been the expected behavior that constants used inside of target regions must be defined in it, and this test was created when we had a different approach in mind.
