Wei Mi b78044c97c [LV] Remove nondeterminacy by changing LoopVectorizationLegality::Reductions ... from DenseMap to MapVector The iteration order of LoopVectorizationLegality::Reductions matters for the final code generation, so we better use MapVector instead of DenseMap for it to remove the nondeterminacy. reduction-order.ll in the patch is an example reduced from the case we saw. In the output of opt command, the order of the select instructions in the vector.body block keeps changing from run to run currently.
