[PATCH] D97828: [LoopInterchange] Disallow interchange when memory accesses are guarded by control flow (PR48057)

[Whitney Tsang via Phabricator via llvm-commits]

Whitney added a comment.

Have you considered the case where the blocks guarded by control flow doesn't have memory operation, but affect memory operation through phi?

  bb1:
    br %cond, bb2, bb3
  bb2:
    br bb4
  bb3:
    br bb4
  bb4:
    %t = phi [ %t2, %bb2 ], [ %t3, %bb3 ]
    store %t, %p
