指定链接器应使用在运行检测的二进制文件后创建的配置文件数据来创建优化的映像。

Specifies that the linker should use the profile data created after running the instrumented binary to create an optimized image.

链接器无法生成映像的最常见的原因是：该链接器的一个或多个输入文件(模块)与安全异常处理程序功能不兼容。

The most common reason for the linker not to be able to produce an image is because one or more of the input files (modules) to the linker was not compatible with the safe exception handlers feature.
