Example

const int GetTheAnswer(int x) noexcept { return 42 + x; } // Could be marked constexpr

void function1() noexcept
{
    const int theAnswer = GetTheAnswer(0);
}

To reduce code analysis noise on new code, this warning isn't issued if the function has an empty implementation.

int function1(){  // no C26497
    return 1;
}
void function2(){} // no C26497
