mostang.com!davidm 2fc4fd6e48 ia64: Rewrite NaT-bit handling for the 3rd time (must be a charm!). 
The previous version was OK for all but one corner case.
	The new version uses slightly more space in the cursor
	(4 extra bytes) but on the other hand, the final result is
	both much more easier to understand and likely faster.
	It also seems more correct, which is always a bonus.

mostang.com!davidm 23dd2c4c4a Update. 
(Logical change 1.181)
 2004-02-27 08:54:25 +00:00
mostang.com!davidm 1c00cf562e (unw_tdep_save_loc): Add new member "nat_bitnr". Define the 
other 7 bytes (which were always there in unw_save_loc_t due
	to padding) as reserved for future use.

(Logical change 1.181)
 2004-02-27 08:54:25 +00:00
mostang.com!davidm 7c7bcebcc0 (unw_get_save_loc): New variable "nat_bitnr". 
Adjust NaT-bit handling.  Much simpler now.
	Pass NULL as new third argument to ia64_scratch_loc().
	Set save_loc->extra.nat_bitnr to the NaT bit number (or 0
	when not accessing a NaT bit).

 2004-02-27 08:54:25 +00:00
mostang.com!davidm 50488aece3 (linux_scratch_loc): Add "nat_bitnr"-pointer argument. 
Handle NaT-bit registers by returning not just the
	NaT-word address, but also the NaT-bit number.
(hpux_scratch_loc): Add "nat_bitnr"-pointer argument.
(ia64_scratch_loc): Likewise.
(access_nat): Add "nat_bitnr" argument.  Rename "loc" to "nat_loc".

	NaT bit-number readily available.

	Handle scratch NaT-bit registers in a more generic fashion,
	now that we can.  Adjust all calls to ia64_scratch_loc() for
	third argument.
