*** Changes since GDB 6.8
+* Process record and replay
+
+ In a architecture environment that supports ``process record and
+ replay'', ``process record and replay'' target can record a log of
+ the process execution, and replay it with both forward and reverse
+ execute commands.
+
+* Reverse debugging: GDB now has new commands reverse-continue, reverse-
+step, reverse-next, reverse-finish, reverse-stepi, reverse-nexti, and
+set execution-direction {forward|reverse}, for targets that support
+reverse execution.
+
+* GDB now supports hardware watchpoints on MIPS/Linux systems. This
+feature is available with a native GDB running on kernel version
+2.6.28 or later.
+
* GDB now has support for multi-byte and wide character sets on the
target. Strings whose character type is wchar_t, char16_t, or
char32_t are now correctly printed. GDB supports wide- and unicode-
If the user types TAB at the end of this command line, the available
completions will be "f1" and "f2".
+* Inlined functions are now supported. They show up in backtraces, and
+the "step", "next", and "finish" commands handle them automatically.
+
* GDB now supports the token-splicing (##) and stringification (#)
operators when expanding macros. It also supports variable-arity
macros.
operation over reliable transport links. Use of this packet is
controlled by the `set remote noack-packet' command.
+vKill
+ Kill the process with the specified process ID. Use this in preference
+ to `k' when multiprocess protocol extensions are supported.
+
qXfer:osdata:read
Obtains additional operating system information
* Support for user-defined prefixed commands. The "define" command can
add new commands to existing prefixes, e.g. "target".
-* New commands
+* New commands (for set/show, see "New options" below)
find [/size-char] [/max-count] start-address, end-address|+search-space-size,
val1 [, val2, ...]
python [CODE]
Invoke CODE by passing it to the Python interpreter.
+macro define
+macro list
+macro undef
+ These allow macros to be defined, undefined, and listed
+ interactively.
+
+info os processes
+ Show operating system information about processes.
+
+* New options
+
+set sh calling-convention
+show sh calling-convention
+ Control the calling convention used when calling SH target functions.
+
set print symbol-loading
show print symbol-loading
Control printing of symbol loading messages.
set debug timestamp
show debug timestamp
- Display timestamps with GDB debugging output.
+ Control display of timestamps with GDB debugging output.
+
+set disassemble-next-line
+show disassemble-next-line
+ Control display of disassembled source lines or instructions when
+ the debuggee stops.
+
+set remote noack-packet
+show remote noack-packet
+ Set/show the use of remote protocol QStartNoAckMode packet. See above
+ under "New remote packets."
+
+set remote query-attached-packet
+show remote query-attached-packet
+ Control use of remote protocol `qAttached' (query-attached) packet.
+
+set remote read-siginfo-object
+show remote read-siginfo-object
+ Control use of remote protocol `qXfer:siginfo:read' (read-siginfo-object)
+ packet.
+
+set remote write-siginfo-object
+show remote write-siginfo-object
+ Control use of remote protocol `qXfer:siginfo:write' (write-siginfo-object)
+ packet.
+
+set displaced-stepping
+show displaced-stepping
+ Control displaced stepping mode. Displaced stepping is a way to
+ single-step over breakpoints without removing them from the debuggee.
+ Also known as "out-of-line single-stepping".
+
+set debug displaced
+show debug displaced
+ Control display of debugging info for displaced stepping.
+
+maint set internal-error
+maint show internal-error
+ Control what GDB does when an internal error is detected.
+
+maint set internal-warning
+maint show internal-warning
+ Control what GDB does when an internal warning is detected.
set exec-wrapper
show exec-wrapper
by default on some platforms. This option keeps the addresses stable across
multiple debugging sessions.
+set non-stop
+show non-stop
+ Control whether other threads are stopped or not when some thread hits
+ a breakpoint.
+
set target-async
+show target-async
Requests that asynchronous execution is enabled in the target, if available.
In this case, it's possible to resume target in the background, and interact
with GDB while the target is running. "show target-async" displays the
with a specified timeout period; this is useful if the stub is launched
in parallel with GDB but may not be ready to accept connections immediately.
-macro define
-macro list
-macro undef
- These allow macros to be defined, undefined, and listed
- interactively.
+set libthread-db-search-path
+show libthread-db-search-path
+ Control list of directories which GDB will search for appropriate
+ libthread_db.
-info os processes
- Show operating system information about processes.
+set schedule-multiple (on|off)
+show schedule-multiple
+ Allow GDB to resume all threads of all processes or only threads of
+ the current process.
* New native configurations
* New targets
