Field Documentation

tree type_change_info::known_current_type

     If we actually can tell the type that the object has changed to, it is
     stored in this field.  Otherwise it remains NULL_TREE.  

Referenced by extr_type_from_vtbl_ptr_store(), and ipa_set_ancestor_jf().

bool type_change_info::multiple_types_encountered

     Set to true if multiple types have been encountered.  known_current_type
     must be disregarded in that case.  

Referenced by extr_type_from_vtbl_ptr_store(), and ipa_set_ancestor_jf().

tree type_change_info::object

     The declaration or SSA_NAME pointer of the base that we are checking for
     type change.  

Referenced by ipa_set_ancestor_jf().

HOST_WIDE_INT type_change_info::offset

     Offset into the object where there is the virtual method pointer we are
     looking for.  

Referenced by ipa_set_ancestor_jf().

bool type_change_info::type_maybe_changed

     Set to true if dynamic type change has been detected.  

Referenced by extr_type_from_vtbl_ptr_store(), and ipa_set_ancestor_jf().
