This option tells the compiler to generate multiple, feature-specific auto-dispatch code paths for x86 architecture processors if there is a performance benefit. It also generates a baseline code path.
This option cannot be used together with any options that may require Intel-specific optimizations (such as [Q]x or [Q]ax).
