-qrestrict

Pragma equivalent

None.

Purpose

Specifying this option is equivalent to adding the restrict keyword to the pointer parameters within all functions, except that you do not need to modify the source file.

Syntax


        .-norestrict-.   
>>- -q--+-restrict---+-----------------------------------------><

Defaults

-qnorestrict. It means no function pointer parameters are restricted, unless you specify the restrict attribute in the source file.

Usage

Using this option can improve the performance of your application, but incorrectly asserting this pointer restriction might cause the compiler to generate incorrect code based on the false assumption. If the application works correctly when recompiled without -qrestrict, the assertion might be false. In this case, this option should not be used.

Note: If you specify both the -qalias=norestrict and -qrestrict options, -qalias=norestrict takes effect.
