* gdbarch.sh (PUSH_DUMMY_CODE): New architecture method, add
	comments noteing that it replaces the old FIX_CALL_DUMMY code.
	* gdbarch.h, gdbarch.c: Re-generate.
	* d10v-tdep.c (d10v_push_dummy_code): New function.
	(d10v_gdbarch_init): Set push_dummy_code.
	* infcall.c (legacy_push_dummy_code): New function.
	(generic_push_dummy_code): New function.
	(push_dummy_code): New function.
	(call_function_by_hand): Call push_dummy_code.  Pass bp_addr,
	instead of dummy_addr, to push_dummy_call.  Move call to
	generic_save_call_dummy_addr to outside of CALL_DUMMY_LOCATION
	switch.
	* sparc-tdep.c (sparc_gdbarch_init): Mention push_dummy_code.

@findex push_dummy_code
@findex FIX_CALL_DUMMY
@anchor{push_dummy_code} Given a stack based call dummy, push the
instruction sequence (including space for a breakpoint) to which the
called function should return.
Set @var{bp_addr} to the address at which the breakpoint instruction
should be inserted, @var{real_pc} to the resume address when starting
the call sequence, and return the updated inner-most stack address.
By default, the stack is grown sufficient to hold a frame-aligned
(@pxref{frame_align}) breakpoint, @var{bp_addr} is set to the address
reserved for that breakpoint, and @var{real_pc} set to @var{funaddr}.
