Change makes sense.



================
Comment at: llvm/test/CodeGen/ARM/bfi-chain-cse-crash.ll:38
+  store i8 %18, i8* %0, align 1
+  br i1 undef, label %.preheader, label %.loopexit

----------------
Can you simplify the testcase so it doesn't have any references to "undef"?  That tends to make testcases a lot more fragile.
