Description

This option enables pointer disambiguation with the restrict qualifier. It enables the recognition of the restrict keyword as defined by the ANSI standard.

By qualifying a pointer with the restrict keyword, you assert that an object accessed by the pointer is only accessed by that pointer in the given scope. You should use the restrict keyword only when this is true. When the assertion is true, the restrict option will have no effect on program correctness, but may allow better optimization.
