/* 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. */
