bd93c64f01 (update_frame_state): Update the IP-cache before doing anything else. 
If we reached the en of the frame-chain, then the remaining
	registers may not be valid/accessible anymore.

1fc6f4e6b3 (unwi_dyn_remote_find_proc_info): If anything goes wrong, return -UNW_ENOINFO. 
Skip over "prev_addr".  Read start/end-IP directly into the "di" structure,
	not into temporary variables.  Skip padding by directly adjusting the
	address (don't bother fetching padding values; that only slows things down).
	Return 0 only if we really did find dynamic unwind info.

54eda6d6fc (_Uia64_find_dyn_list): Add "gp" argument. 
Fix typo in address-offset for the "off" variable.
	Adjust for the fact that the dyn-info list address is now gp-relative.

5660a59ba1 (_U_dyn_info_list): Mark it as .hidden so we can do a @gprel() reloc against it. 
(.info): Use @gprel() reloc instead of @segrel() reloc for _U_dyn_info_list.
	The latter doesn't work because the unwind-info is in a different segment.
(ia64_init): Clear unw.r0.

0d0c84f63c (rbs_switch): Rename from rbs_record_switch() and greatly simplify it because 
we now switch to the new backing-store immediately.
(rbs_underflow): Remove.
(rbs_find_stacked): No longer assume that c->bsp is contained in the current
	rbs.  If it is not, first find the backing-store that's backing c->bsp.
