[RFA] target adjust pc after break with itself

[teawater]

Hi Pedro,

According to your idea, I write a patch
"target_adjust_pc_with_itself.txt" for it. It's for the main trunk and
20080930 branch.

2008-11-02  Hui Zhu  <teawater@gmail.com>

	* target.h (target_ops): Add "to_adjust_pc_with_itself".
	Return true if target adjust pc after break with itself.
	(target_adjust_pc_with_itself): New macro.
	Call "to_adjust_pc_with_itself".
	* target.c (update_current_target): Set
	"to_adjust_pc_with_itself".
	* infrun.c (adjust_pc_after_break): If
	"target_adjust_pc_with_itself" return true, not adjust pc.

To make P record support it. I make another patch
"record_adjust_pc_with_itself.txt".

2008-11-02  Hui Zhu  <teawater@gmail.com>

	* record.c (record_adjust_pc_with_itself): New function.
	Return true.
	(init_record_ops): Set to_adjust_pc_with_itself point to
	record_adjust_pc_with_itself.

Thanks,
Hui
