### /Op Compiler Option

Syntax: | Default:
/Op[+|-] | /Op+

Use /Op to perform optimizations involving the stack pointer.

By default, optimizations involving the stack pointer are always performed.

Specify /Op- when you optimize code that directly manipulates the stack pointer. Using /Op- decreases the performance of your executable or dynamic link library file.
