+defm : Zn4WriteResYMMPair<WriteFAdd64Y, [Zn4FPFAdd01], 3, [1], 1>; // Floating point double add/sub (YMM).
+defm : Zn4WriteResZMMPair<WriteFAdd64Z, [Zn4FPFAdd01], 3, [1], 2>; // Floating point double add/sub (ZMM).
+defm : Zn4WriteResXMMPair<WriteFCmp, [Zn4FPFMul01], 2, [2], 1>;  // Floating point compare.
----------------
I'd expected the zmm pairs to be something like:
```
defm : Zn4WriteResZMMPair<WriteFAdd64Z, [Zn4FPFAdd01], 3, [2], 1>;
```
