-/* GENERIC DUMMY FRAMES
-  
-   The following code serves to maintain the dummy stack frames for
-   inferior function calls (ie. when gdb calls into the inferior via
-   call_function_by_hand).  This code saves the machine state before
-   the call in host memory, so we must maintain an independent stack
-   and keep it consistant etc.  I am attempting to make this code
-   generic enough to be used by many targets.
- 
-   The cheapest and most generic way to do CALL_DUMMY on a new target
-   is probably to define CALL_DUMMY to be empty, CALL_DUMMY_LENGTH to
-   zero, and CALL_DUMMY_LOCATION to AT_ENTRY.  Then you must remember
-   to define PUSH_RETURN_ADDRESS, because no call instruction will be
-   being executed by the target.  Also FRAME_CHAIN_VALID as
-   generic_{file,func}_frame_chain_valid and FIX_CALL_DUMMY as
-   generic_fix_call_dummy.  */
+/* If the PC falls in a dummy frame, return a dummy frame
+   unwinder.  */
 
-/* Assuming that FRAME is a dummy, return a register value for the
-   previous frame.  */
