Xcode配置文件不能與程序集一起使用

Question

我試圖在Xcode 7.1.1中開始分析我的iOS C++應用程序。但是當我去「產品」 - 「配置文件」時，我收到了很多與彙編代碼相關的錯誤。

我可以在iPad 4上構建並運行應用程序，而不會出錯。該問題僅與分析相關。

我嘗試重新啓動，清理並更改爲推薦的項目設置。

我可以直接從Instruments使用「OpenGL ES Analysis」模板進行配置。但我需要「核心數據」來分析緩存未命中。我無法從樂器中啓動它 - 記錄按鈕被阻止。

下面是錯誤消息的一部分：

Answer 1

你編譯項目爲ARM64，但你的彙編文件是使用只只支持32位ARM指令的目標。值得注意的是，它使用了與Thumb相關的指令，意味着代碼使用了ARM64代碼中不支持的Thumb 2指令集。

檢查是否在啓用分析時意外切換到構建64位項目。
