rjmccall added inline comments.


================
Comment at: clang/lib/CodeGen/CGExprScalar.cpp:3397
   Value *Result;
-  if (ResultFixedSema.isSaturated()) {
-    llvm::Intrinsic::ID IID = ResultFixedSema.isSigned()
-                                  ? llvm::Intrinsic::sadd_sat
-                                  : llvm::Intrinsic::uadd_sat;
-    Result = Builder.CreateBinaryIntrinsic(IID, FullLHS, FullRHS);
+  if (BinOp->getOpcode() == BO_Add) {
+    if (ResultFixedSema.isSaturated()) {
