craig.topper added inline comments.


================
Comment at: llvm/lib/Target/RISCV/RISCVTargetTransformInfo.cpp:236
+    std::pair<InstructionCost, MVT> LT = TLI->getTypeLegalizationCost(DL, Ty);
+    return LT.first + BaseCost;
+  }
----------------
LT.first is usually a multiplier. Why is this addition?
