	gdb            : ChangeLog ia64-tdep.c 

Log message:
	2003-10-23  Jeff Johnston  <jjohnstn@redhat.com>
	
	* ia64-tdep.c: (ia64_frame_cache): Add new prev_cfm field.
	(pseudo_regs): Add comment regarding register stack registers.
	(ia64_alloc_frame_cache):  Initialize new prev_cfm field to 0.
	(floatformat_valid): New static routine.
	(floatformat_ia64_ext): Add name field and set up is_valid routine
	to floatformat_valid().
	(examine_prologue):  For the previous cfm, use
	frame_unwind_register()
	if the cfm is not stored in a register-stack register.  Save the
	previous cfm value in the prev_cfm field.  Add debug output.
	(ia64_frame_this_id): Use frame_id_build_special() to also register
	the bsp.  Add debug output.
	(ia64_sigtramp_frame_this_id): Ditto.
	(ia64_frame_prev_register):  Look at cache saved_regs for a few more
	registers and also add some checks for framelessness before accepting
	current register values for fields such as return address.  For cfm,
	use the cached prev_cfm field if available.  Add comment to explain
	PSR logic.  Add debug output.
	(ia64_sigtramp_frame_init_saved_regs): Save the bsp and sp addresses
	as part of initialization.
	(ia64_sigtramp_frame_cache): Hard-code stack size as it can't be
	calculated.  Cache the bsp and cfm values.
	(ia64_sigtramp_frame_prev_register): Add logic to this routine out
	instead of using ia64_frame_prev_register() which doesn't expect most
	registers to be saved.  The saved values for bsp and sp
	can be taken from the cache.  Add debug output.
	(ia64_push_dummy_call): Use frame_id_build_special() to also register
	the bsp.
