become unavailable. The AssumptionCache is now immutable but it still needs to respond to DomTree invalidation if it ended up caching one. This lets us remove one of the explicit invalidates of LVI but the other one continues to avoid hitting a latent bug. llvm-svn: 292769

; 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.
