-/* 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,
-   DEPRECATED_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 DEPRECATED_FRAME_CHAIN_VALID as
-   generic_{file,func}_frame_chain_valid and do not set
-   DEPRECATED_FIX_CALL_DUMMY.  */

 /* If the PC falls in a dummy frame, return a dummy frame
    unwinder.  */
