因为最佳化可能变更编译器所建立的程序码，我们会建议您侦错应用程序，并测量它的效能，然后最佳化程序码。
Because optimization might change the code created by the compiler, we recommend that you debug your application and measure its performance, and then optimize your code.
这是正常的行为，因为某些警告仅与最佳化的程序码相关。
This behavior is expected because some warnings relate only to optimized code.
若要使执行效能最佳化，您可以让您的程序码执行较少的堆叠查核行程，然而，您必须确定并没有泄露任何安全漏洞。
To optimize performance, you can have your code perform fewer stack walks; however, you must be sure that you do not expose a security weakness whenever you do this.
您可能也注意到，当您以最佳化编译程序码时，会出现某些额外的警告讯息。
You might notice additional warning messages when you compile your code with optimization.
说明在应用程序中使用程序码片段的最佳作法。

对于区域通用子运算式最佳化，编译器会检查程序码的短区段中有没有通用子运算式。
For local common subexpression optimization, the compiler examines short sections of code for common subexpressions.
