a2b8866fb3 ia64: Remove erroneous calls to rotate_gr() during script-execution. 
Fix NaT-bit handling test-case involving rotated regs.

BKrev: 405aace43GdnidC9YEnxvj_7mchwFg
 2004-03-19 08:18:44 +00:00
mostang.com!davidm
eed0c54d28 (run_script): Remove erroneous calls to rotate_gr(). The unwind 
directives specify physical stacked register numbers and
	the register-backing store always represents physical
	registers, so it was wrong to rotate here.

96d2898321 (CALL_NEXT_PTR): Like CALL_NEXT(), except that the two argument 
registers are passed via macro args.
(CALL_NEXT): Define in terms of CALL_NEXT_PTR().
(rotate_regs): Fix it so it doesn't overwrite any local registers
	once they are rotated.  Note: it's OK to write the output
	registers, since those are outside of the rotating partition.

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.

1c00cf562e (unw_tdep_save_loc): Add new member "nat_bitnr". Define the

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).

(ia64_scratch_loc): Likewise.
