================
Comment at: llvm/lib/Target/AArch64/AArch64InstrInfo.cpp:5173
       MI = MRI.getUniqueVRegDef(MO.getReg());
+    if (MI && MI->getOpcode() == TargetOpcode::COPY &&
+        MI->getOperand(1).getReg().isVirtual())
----------------
Perhaps a comment that we ignore the copy in `FMUL(COPY(DUP(..)))`?
