restrict, Qrestrict

Determines whether pointer disambiguation is enabled with the restrict qualifier.

Syntax

Linux:
-restrict
-no-restrict
macOS:
-restrict
-no-restrict
Windows:
/Qrestrict
/Qrestrict-
Arguments
None
Default
-no-restrict
or
/Qrestrict-
Pointers are not qualified with the restrict keyword.
Description
This option determines whether pointer disambiguation is enabled with the restrict qualifier. Option
-restrict
and
/Qrestrict
enable 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.
Alternate Options
None
