1 ; The IR below was crafted so as:
2 ; 1) To have a loop, so we create a loop pass manager
3 ; 2) To be "immutable" in the sense that no pass in the standard
4 ; pipeline will modify it.
5 ; Since no transformations take place, we don't expect any analyses
6 ; to be invalidated.
7 ; Any invalidation that shows up here is a bug, unless we started modifying
8 ; the IR, in which case we need to make it immutable harder.
