[PATCH] D154415: [LV] Change the test cases to ensure that the trip count is not zero. (NFC)

[Ayal Zaks via Phabricator via llvm-commits]

Ayal added inline comments.


================
Comment at: llvm/test/Transforms/LoopVectorize/select-min-index.ll:23
   %min.idx.next = select i1 %cmp, i64 %iv, i64 %min.idx
   %iv.next = add nuw nsw i64 %iv, 1
+  %exitcond.not = icmp eq i64 %iv.next, %n
----------------
Note that checking if %iv.next is zero after bumping it with no-wrap flags (having initialized it to zero) is undefined. As is the case now if %n is zero.
