================
Comment at: llvm/lib/Target/AArch64/AArch64ISelLowering.cpp:22984
     SDNode *ExtractLowUser = *ExtractLow.getNode()->use_begin();
     if (ExtractLowUser->getOpcode() != N->getOpcode())
       HasFoundMULLow = false;
----------------
Minor nit: add braces around "if" body so it more obviously matches the "else".
