* Better reconstruction of tracepoints after disconnected tracing
|
||||||
|
|
||||||
|
GDB will attempt to download the original source form of tracepoint
|
||||||
|
definitions when starting a trace run, and then will upload these
|
||||||
|
upon reconnection to the target, resulting in a more accurate
|
||||||
|
reconstruction of the tracepoints that are in use on the target.
|
||||||
|
|
||||||
|
* Observer mode
|
||||||
|
|
||||||
|
You can now exercise direct control over the ways that GDB can
|
||||||
|
affect your program. For instance, you can disallow the setting of
|
||||||
|
breakpoints, so that the program can run continuously (assuming
|
||||||
|
non-stop mode). In addition, the "observer" variable is available
|
||||||
|
to switch all of the different controls; in observer mode, GDB
|
||||||
|
cannot affect the target's behavior at all, which is useful for
|
||||||
|
tasks like diagnosing live systems in the field.
|
||||||
|
|
||||||
|
* The new convenience variable $_thread holds the number of the
|
||||||
|
current thread.

Set individual permissions for GDB effects on the target. Note that
|
||||||
|
some of these settings can have undesirable or surprising
|
||||||
|
consequences, particularly when changed in the middle of a session.
|
||||||
|
For instance, disabling the writing of memory can prevent
|
||||||
|
breakpoints from being inserted, cause single-stepping to fail, or
|
||||||
|
even crash your program, if you disable after breakpoints have been
|

inserted. However, GDB should not crash.
