gdb-gdb.py: strip typedefs in intrusive_list printer assertion
When debugging gdb itself and trying to print a intrusive_list that has
more than one element, I get:
File "/home/simark/build/binutils-gdb-all-targets/gdb/gdb-gdb.py", line 365, in _children_generator
node_ptr = self._as_node_ptr(elem_ptr)
^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/home/simark/build/binutils-gdb-all-targets/gdb/gdb-gdb.py", line 345, in _as_node_ptr
assert elem_ptr.type.code == gdb.TYPE_CODE_PTR
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AssertionError
This is because node_ptr is a typedef
(intrusive_list_base_iterator::pointer). Add a call to strip_typedefs
to get to the real type.
Enhance gdb.gdb/python-helper.exp with a test that would have caught
this bug.
