示例1: VisitCompoundStmt

    bool VisitCompoundStmt(CompoundStmt* CS) {
      for(CompoundStmt::body_iterator I = CS->body_begin(), E = CS->body_end();
          I != E; ++I) {
        if (!isa<BinaryOperator>(*I))
          continue;

        const BinaryOperator* BinOp = cast<BinaryOperator>(*I);
        if (isAutoCandidate(BinOp)) {
          ASTContext& C = m_Sema->getASTContext();
          VarDecl* VD 
            = cast<VarDecl>(cast<DeclRefExpr>(BinOp->getLHS())->getDecl());
          TypeSourceInfo* ResTSI = 0;
          TypeSourceInfo* TrivialTSI 
            = C.getTrivialTypeSourceInfo(VD->getType());
          Expr* RHS = BinOp->getRHS();
          m_Sema->DeduceAutoType(TrivialTSI, RHS, ResTSI);
          VD->setTypeSourceInfo(ResTSI);
          VD->setType(ResTSI->getType());
          VD->setInit(RHS);
          Sema::DeclGroupPtrTy VDPtrTy = m_Sema->ConvertDeclToDeclGroup(VD);
          // Transform the AST into a "sane" state. Replace the binary operator
          // with decl stmt, because the binop semantically is a decl with init.
          StmtResult DS = m_Sema->ActOnDeclStmt(VDPtrTy, BinOp->getLocStart(), 
                                                BinOp->getLocEnd());
          assert(!DS.isInvalid() && "Invalid DeclStmt.");
          *I = DS.take();
        }
      }
      return true; // returning false will abort the in-depth traversal.
    }
