[Allen zhong via Phabricator via llvm-commits]

Allen added a comment.

Thanks for your analysis.  The bug is brought by the following code in function mergeComparisons.
As the comparisons is reorded according the memory offset (https://reviews.llvm.org/D149542), so the origin last comparison BB may be not the Comparisons[Comparisons.size() - 1].BB

  BasicBlock *const TailBB = Comparisons[Comparisons.size() - 1].BB;
