Description

Before assigning a pointer to a member in C++, you must ensure that the pointer to the member is not NULL in order to generate correct and safe code. In embedded systems development, the problem is to generate the denser code while avoiding overhead whenever possible (this NULL check code is a good example). If you can ensure this pointer to a member will never be NULL, then this NULL check is useless. This option enables you to switch off the code generation for the NULL check.
