Last change on this file since 3162858 was 3162858, checked in by Chris Johns <chrisj@…>, on Aug 26, 2014 at 4:57:57 AM

gdb-python: Update so 'rtems task' lists the classic tasks.

This is a first pass at cleaning up the support. To use:

$ waf configure --prefix=$HOME/development/rtems/4.11
$ waf build install

Start GDB and break at Init:

(gdb) py import rtems
(gdb) rtems task

will list the classic API tasks.
