Output gcc -fdump-tree-original

Question

If I discard the code generated by GCC for the virtual destructor (with -fdump-tree-original), I get something like this:

;; Function virtual Foo::~Foo() (null)
;; enabled by -tree-original

{
  <<cleanup_point <<< Unknown tree: expr_stmt
  (void) (((struct Foo *) this)->_vptr.Foo = &_ZTV3Foo + 8) >>>
>>;
}
<D.20148>:;
if ((bool) (__in_chrg & 1))
  {
    <<cleanup_point <<< Unknown tree: expr_stmt
  operator delete ((void *) this) >>>
>>;
  }

My question is: where is the code after " <D.20148>:;"? It is outside the destructor, so when does this code execute?

Answer 1

This is similar to the code generated by the compiler to control the actual freeing of memory after calling the destructor and should be executed immediately after the destructor code.
