I'm not following your question.

The sequence here is that we constant-fold a terminator (deleting an edge), then continue iterating through all the blocks in the function, and eventually crash when LVI discovers a cycle in a loop which was made unreachable.  Which blocks is JumpThreading supposed to tell LVI about?
