================
Comment at: llvm/test/Transforms/LoopVectorize/memdep.ll:94
 
-; Plausible dependence of distance 1 - cannot be vectorized (without reordering
-; accesses).
----------------
Just fix the test to check new output?

+; RUN: opt < %s -O2 -force-vector-width=4 -force-vector-interleave=1 -S | FileCheck %s
+; RUN: opt < %s -O2 -force-vector-interleave=1 -S | FileCheck %s -check-prefix=REVERT

----------------
Please don't use `-O2`, this should only be `-loop-vectorize`
