Weird Code in parse.y (java_layout_seen_class_methods)


Hi,

  Consider the body of java_layout_seen_class_methods()
in parse.y:
-------------------------- 8< --------------------------
   7577 void java_layout_seen_class_methods (void)
   7578 {
   7579   tree previous_list = all_class_list;
   7580   tree end = NULL_TREE;
   7581   tree current;
   7582
   7583   while (1)
   7584     {
   7585       for (current = previous_list;
   7586            current != end; current = TREE_CHAIN (current))
   7587         layout_class_methods (TREE_TYPE (TREE_VALUE (current)));
   7588
   7589       if (previous_list != all_class_list)
   7590         {
   7591           end = previous_list;
   7592           previous_list = all_class_list;
   7593         }
   7594       else
   7595         break;
   7596     }
   7597 }
-------------------------- 8< --------------------------

How can code between 7590-7593 ever execute?
And why is there a while(1) around the for loop?

Is this some vestigial code that should have been
removed?

BTW, the method name is not the first word on
the line #7577.

Thanks,
Ranjit.
