Clarification on Rule 20.8 - anuj1085 - 05-03-2015
In the below case
#if 10
----
#elif 20
----
#endif
Since the part of the code
#elif 20
----
#endif
Is never gonna execute, is the rule applicable to this part of code i.e the part #elif 20 will be ignored while compilation so should the violation should be reported on it ?
Re: Clarification on Rule 20.8 - misra-c - 13-03-2015
The amplification of rule 20.8 states:
Quote: This rule does not apply to controlling expressions in preprocessing directives which are not evaluated. Controlling expressions are not evaluated if they are within code that is being excluded and cannot have an effect on whether code is excluded or not.Therefore this rule does not apply to the "#elif 20". However the "#if 10" is a violation of rule 20.8
