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></div></blockquote><div><br></div><div><a href="http://llvm.org/svn/llvm-project/cfe/trunk/lib/CodeGen/CGClass.cpp">http://llvm.org/svn/llvm-project/cfe/trunk/lib/CodeGen/CGClass.cpp</a><br></div><div><br></div><div>Search for "EnterDtorCleanups".</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex"><div bgcolor="#FFFFFF" text="#000000">

<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>
</div>

<div>We do not model the implicit member and base
destruction actions performed by a destructor in the AST.</div>
