JanekvO added inline comments.


================
Comment at: llvm/lib/CodeGen/MachinePipeliner.cpp:2792
             return false;
+          if (InstrToCycle[SI.getSUnit()] == CycleDef)
+            return false;
----------------
Is it possible to get an ordering where a use is scheduled prior to the `CycleDef`?
