================
Comment at: llvm/lib/Target/RISCV/RISCVISelLowering.cpp:13486
           continue;
-        NewC.insertBits(Val.getConstantOperandAPInt(i),
-                        i * Val.getScalarValueSizeInBits());
+        NewC.insertBits(Val.getConstantOperandAPInt(i).trunc(EltSize),
+                        i * EltSize);
----------------
What happens if we're truncating a constant that is larger than EltSize?
