+
+	Add record target to GDB.
+
+	* linux-record.c, linux-record.h: New files. Record and reverse target
+	code for GNU/Linux.
+	* record.c, record.h: New files. Record and reverse target.
+ 	* Makefile.in: Add files record.c, record.h, linux-record.c and
+	linux-record.h.
+	* configure.tgt: Add files linux-record.c and linux-record.h.
+	* gdbarch.c, gdbarch.h: Add elements "record" and "record_dasm".
+	* i386-linux-tdep.c (linux_record_tdep): New static variable. I386 Linux
+	record target-dependent stuff.
+	(i386_linux_intx80_sysenter_record): New function. Record the running
+	message of I386 Linux system call.
+	(i386_linux_init_ab): Initialize the linux_record_tdep. Add
+	i386_linux_intx80_sysenter_record to struct tdep.
+	* i386-tdep.c (i386_record_modrm, i386_record_lea_modrm_addr,
+	i386_record_lea_modrm, i386_record): New functions. Record the running
+	message of I386 instruction.
+	(i386_gdbarch_init): Add i386_record to struct gdbarch.
+	* i386-tdep.h (gdbarch_tdep): Add elements "i386_intx80_record" and
+	"i386_sysenter_record" to be the interfaces that record the running
+	message of instruction "intx80" and "sysenter".
+	* infcmd.c (step_prev_frame_id): New global variable. When GDB is in the
+	reverse debug mode, it is used to make sure if inferior return to the
+	prev function.
+	(step_1, step_once, until_next_command): Set the value of variable
+	"step_prev_frame_id".
+	(kill_if_already_running): If record target is used, output special
+	query.
+	* inferior.h (step_prev_frame_id): Extern.
+	* inflow.c (kill_command): If record target is used, output special
+	query.
+	* infrun.c (reverse_resume_need_step): New static variable. When the
+	record function want inferior step before call function "keep_going",
+	"reverse_resume_need_step" will be set to 1.
+	(displaced_step_ptid, displaced_step_original, displaced_step_copy): Set
+	them from static to global because record.c use them.
+	(use_displaced_stepping): If record target is in replay mode, it will
+	return false.
+	(proceed): Call function "record_not_record_set" if record target is
+	open.
+	(handle_inferior_event): Change some Handle when execdir of target is
+	reverse or record target is open to make reverse execute work well.
+	* linux-nat.c (my_waitpid_record): New function. Call function
+	"my_waitpid" and check the result with itself to make record target
+	speed up.
+	(linux_nat_wait): If record target is open and not the sigle step, call
+	function "my_waitpid_record".
+	* regcache.c (regcache_raw_write): Set regnum to
+	record_regcache_raw_write_regnum.
+	* target.h (strata): Add element "record_stratum".
