-/* 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. */
