 # GDB macros for analyzing RTEMS threads
 #
-#
-#  20 July 2008 - Chris:
-#    + Use "struct Thread_Control_struct".
-#
-#  7 August 2006 - Joel:
-#    + Use Thread_Control_struct not Thread_Control to make gdb happy.
-#      Who knows why this makes gdb happier?
-#  10 July 2006 - Joel:
-#    + Renamed all methods to start with rtems_ if public and rtems_helper_
-#       if private
-#    + Merged code to dump timer delta chain
-#    + Added code to dump Classic Semaphores, Message Queues, and Regions
-#    + Added support code to dump SuperCore Mutexes, Semaphores,
-#        Message Queues, Thread Queues, and Heaps
-#
 #  TODO:
-#    + rtems_task_backtrack is CPU specific.  How to fix?
-#    + Need to detect when POSIX and ITRON are not configured so
-#      a nice message is printed when those commands are used
+#    + rtems_task_backtrack is CPU specific.  How to detect CPU in gdb?
+#    + Generally need to detect when options like SMP, POSIX, etc. are
+#      enabled/disabled and impact code generation for data structures.
 #    + Add support for Classic API
 #       - Periods
 #       - Timers
