Do you mean `right`?



================
Comment at: llvm/lib/Target/X86/X86InstrAVX512.td:12580
                                    EVEX_4V, EVEX_CD8<32, CD8VF>, T8PD,
-                                   Sched<[sched.Folded, sched.ReadAfterFold]>;
+                                   Sched<[sched.Folded, sched.ReadAfterFold,
+                                          sched.ReadAfterFold]>;
----------------
It's a mystery to me that AVX512 has a lot of 3 ops instructions but not even have one `ReadAfterFold,` in X86InstrAVX512.td
```
grep -rn 'ReadAfterFold,' llvm/lib/Target/X86/X86InstrAVX512.td
```
