Does Parasoft Static Analysis support
standard [[fallthrough]] attribute or gcc attribute((fallthrough))? If not, are there plans to support them?

    Hi @george_vlasov,

    In this moment [[fallthrough]] (or gcc attr.) is not supported. We do not have this in our plans for the near feature, but it is a valid request, there are several rules which could benefit from fallthrough being correctly handled. Do you have a specific rule which is noisy because of this?

    It's not that any rules are noisy, but rather we are going to switch to C++17 standard and will be using [[fallthrough]] attribute instead of the comment, and we need C++Test to support it, specifically rule CODSTA-56-3 is gonna fail without such support:

    All 'case' and 'default' labels of 'switch' statement should have an explicit 'break' or a 'return'
    statement, or 'fall through' comment [CODSTA-56-3]
    DESCRIPTION
    All 'case' and 'default' labels of 'switch' statement should have:

    • an explicit unconditional 'break' or a 'return' statement or
    • at the end a 'fall through' comment containing "fall through" phrase
      (checked case insensitive).
