================
Comment at: llvm/lib/Target/LoongArch/LoongArchISelLowering.cpp:1741
+    return isa<LoadInst>(I) || isa<StoreInst>(I);
+  } else {
+    unsigned Size = 0;
----------------
No need to use `else` after `return`.


================
Comment at: llvm/lib/Target/LoongArch/LoongArchISelLowering.cpp:1742-1744
+    unsigned Size = 0;
+    if (isa<StoreInst>(I))
+      Size = I->getOperand(0)->getType()->getIntegerBitWidth();
----------------
Size = isa<StoreInst>(I) ? I->getOperand(0)->getType()->getIntegerBitWidth() : 0;
