    Richard,<br>
    <br>
    Thanks for the quick reply. <br>
    May be you can point me to the code in LLVM where I can find the
    logic I need (find fields which must be implicitly
    created/destroyed)?<br>
    As destructors have to be called for fields, I assume there is such
    logic. <br>
    May be somewhere at AST-of-destructor => IR conversion layer?<br>
    <br>
    Thanks!<br>
    Vladimir.<br>

                  <div>Hello,<br>
                    <br>
                    How can I find by AST visitor for which fields
                    destructors are called?<br>
                    <br>
                    for the following code:<br>
                      struct WithDestr {<br>
                        int *i;<br>
                    <br>
                        WithDestr() : i(nullptr) { }<br>
                    <br>
                        virtual ~WithDestr() { delete i; }<br>
                      };<br>
                    <br>
                      struct Other {<br>
                        WithDestr d;<br>
                        long *ptr;<br>
                        Other() { }<br>
                        virtual ~Other() { delete ptr; }<br>
                      };<br>
                    <br>
                  </div>
                  In AST I see only the construction of field d, but do
                  not see anywhere destruction of d.<br>
