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