================
Comment at: llvm/lib/Target/RISCV/RISCVRedundantCopyElimination.cpp:145
   // BEQ/BNE. Conservatively mark as much as we can live.
-  CondBr->clearRegisterKills(TargetReg, TRI);
+  Cond[1].setIsKill(false);
 
----------------
This line is wrong. It’s a copy of the operand not a reference to the original operand. This doesn’t change the original instruction
