Some tests fail if IREE is configured with some default backends disabled.

[bjacob]

To reproduce, cmake -DIREE_TARGET_BACKEND_DEFAULTS=OFF, clear cached CMake variables controlling backends, and rebuild and test.

These tests are currently failing: (and that's with #14035 fixing a few already)

@bjacob Should this be assigned to you? Or looking for an owner?

[bjacob]

I can try to find cycles and it's not time-sensitive anyway, so i can just self-assign without implying i'll be working on it.
