Sort the operands of the other entries in the current vectorization root according to the first entry's operands opcodes. %conv0 = uitofp ... %load0 = load float ... = fmul %conv0, %load0 = fmul %load0, %conv1 = fmul %load0, %conv2 Make sure that we recursively vectorize <%conv0, %conv1, %conv2> and <%load0, %load0, %load0>. This makes it more likely to obtain vectorizable trees. We have to be careful when we sort that we don't destroy 'good' existing ordering implied by source order. radar://15080067 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191977 91177308-0d34-0410-b5e6-96231b3b80d8
