PM22811: MISRA_16_1_i rule misses violation in Logiscope 6.6.3

APAR status

• Closed as program error.

Error description

• As per the rule, Functions like int foo(int num,...) are not
  allowed with variable numbers of arguments.
  When the below code is checked for MISRA_16_1_i in Logiscope
  6.3, we observe the violations reported for Function
  definitions, declarations and calls.
  However, the same in Logiscope 6.6.3, reports violations for
  only function definitions.
  
  #include 'misra.h'
  
  static void mc2_1601a ( uint16_t variable_arg1, ... );    /*
  Violation : isn't detected anymore in 6.6.3 */
  
  
  void mc2_1601 ( void )
  {
    uint16_t var_argument = get_uint16 ( );
  
    mc2_1601a ( var_argument , var_argument );              /*
  Violation : isn't detected anymore i en 6.6.3 */
  }
  
  /* Function defined with variable number of arguments */
  static void mc2_1601a ( uint16_t variable_arg1, ... )      /*
  Violation  detected both in 6.3 and 6.6.3 */
  {
    use_uint16 ( variable_arg1 );
  }
  

Local fix

Problem summary

• As per the rule, Functions like int foo(int num,...) are not all

  for Function definitions, declarations and calls.
  However, the same in Logiscope 6.6.3, reports violations for onl

Problem conclusion

• Fixed in Rational Logiscope 6.6.3 iFix1.
