V3513. AUTOSAR. Every switch-clause should be terminated by an unconditional 'break' or 'throw' statement.

Mar 03 2021

This diagnostic rule is based on the software development guidelines developed by AUTOSAR (AUTomotive Open System ARchitecture).

Each label of a 'switch' statement should end with a 'break' statement or a 'throw' expression placed outside the condition.

Adding the ending statements guarantees that the execution flow will not "fall through" to the next label and also helps avoid mistakes when adding new labels.

The only exception to this rule is a series of empty labels.

Here is an example of code triggering this warning:

void example_1(int cond, int a)
{
  switch (cond)
  {
  case 1:
  case 2:
    break;
  case 3:  // <=
    if (a == 42)
    {
      DoSmth();
    }
  case 4:  // <=
    DoSmth2();
  default: // <=
    ;
  }
}

Fixed code:

void example_1(int cond, int a)
{
  switch (cond)
  {
  case 1:
  case 2:
    break;
  case 3:
    if (a == 42)
    {
       DoSmth();
    }
    break;
  case 4:
    DoSmth2();
    break;
  default:
    /* No action required */ 
    break;
  }
}
