Looks like this is not submitted yet, so I am going to do it
(but in the future, if you don't have commit access, please ask explicitly)

void LoopEmitter::exitForLoop(RewriterBase &rewriter, Location loc,
   } else {
     auto parOp = llvm::cast<scf::ParallelOp>(loopInfo.loop);
     if (!reduc.empty()) {
       assert(reduc.size() == parOp.getInitVals().size() && reduc.size() == 1);
       Operation *redExp = reduc.front().getDefiningOp();
       // Reduction expression should have no use.
       assert(redExp->getUses().empty());
       // This must be a binary operation.

       // commutative.
       assert(redExp->getNumOperands() == 2 && redExp->getNumResults() == 1);
 
       Value redVal = parOp.getInitVals().front();
       Value curVal;
       if (redExp->getOperand(0) == redVal)
         curVal = redExp->getOperand(1);
       else if (redExp->getOperand(1) == redVal)
