[PATCH] D73490: [LV] Remove nondeterminacy by changing LoopVectorizationLegality::Reductions from DenseMap to MapVector

[David Blaikie via Phabricator via llvm-commits]

dblaikie added a comment.

Out of curiosity - does this test case fail reliably with LLVM_REVERSE_ITERATION enabled (before the patch to fix the iteration order)? (or with it disabled, etc) or is it noisy failing (pretty even % of the time?) even without that?
