[Joel Brobecker <brobecker@adacore.com>]

Thsi patch updates the GDB Manual with the new command, as well as
with the addition to the `-list-features' command.

gdb/doc/ChangeLog:

        * gdb.texinfo (GDB/MI Ada Tasking Commands): New node.
        (GDB/MI Miscellaneous Commands): Add `ada-task-info'
        as possible feature returned by the `-list-features'
        command.

Tested on x86_64-linux. Ok to apply?

Thanks,
-- 
Joel

+
+@subsubheading Synopsis
+
+@smallexample
+ -ada-task-info [ @var{task-id} ]
+@end smallexample
+
+Reports information about either a specific Ada task, if the
+@var{task-id} parameter is present, or about all Ada tasks.
+
+@subsubheading @value{GDBN} Command
+
+The @samp{info tasks} command prints the same information
+about all Ada tasks.
+
+@subsubheading Result
+
+The result is a table of Ada tasks.  The following columns are
+defined for each Ada task:
+
+@table @samp
+@item current
+This field exists only for the current thread.  It has the value @samp{*}.
+
+@item id
+The identifier that @value{GDBN} uses to refer to the Ada task.
+
+@item task-id
+The identifier that the target uses to refer to the Ada task.
+
+@item thread-id
+The identifier of the thread corresponding to the Ada task.
+
+This field should always exist, as Ada tasks are always implemented
+on top of a thread.  But if @value{GDBN} cannot find this corresponding
+thread for any reason, the field is omitted.
+
+@item parent-id
+This field exists only when the task was created by another task.
+In this case, it provides the ID of the parent task.
+
+@item priority
+The base priority of the task.
+
+@item state
+The current state of the task.
+
+@item name
+The name of the task.
