@xbolva00 Are you still working on this atm or are you waiting to see what happens with https://discourse.llvm.org/t/rfc-cmov-vs-branch-optimization/59628 ?



================
Comment at: llvm/include/llvm/CodeGen/MachineInstr.h:113
                                         // this instruction.
+    Unpredictable    = 1 << 16,         // Instruction is unpredictable.
   };
----------------
I don't suppose there's any existing MIFlag bits that we can get rid of?
