Re: [RFA] Displaced stepping just enable in non-stop mode


Hi Joel,

According to your mail, I make a new patch.

2008-10-08  Hui Zhu  <teawater@gmail.com>

	Displaced stepping can be set to
	auto (enable in non-stop mode), on, off.

	* infrun.c (can_use_displaced_stepping): Change type to const
	char pointer.
	(can_use_displaced_stepping_auto): New string.
	(can_use_displaced_stepping_on): New string.
	(can_use_displaced_stepping_off): New string.
	(can_use_displaced_stepping_enum): New array.
	(use_displaced_stepping): Return non-zero if displaced stepping
 	is auto, and can be used with GDBARCH, and in non-stop mode.
	Return non-zero if displaced stepping is on, and can be used
	with GDBARCH.
	(_initialize_infrun): "can-use-displaced-stepping" function
	change to add_setshow_enum_cmd.

Thanks,
Hui
