Bug ID: 16113
Summary: gdb.Value needs a way to reference a superclass
sub-object
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: python
Assignee: unassigned at sourceware dot org
Reporter: tromey at redhat dot com
Right now if you have a gdb.Value whose type is some class,
and the class has a superclass, then there is no good way
to refer to the phony "field" that gdb creates to represent
the superclass.
That is, for an ordinary field you can use value["fieldname"] --
but the superclass field doesn't have a regular name.
We should extend valpy_getitem to also accept a gdb.Field
as an index. This way a program could use the Type API to
find the superclass field, and then pass this to the [] operation
to extract the desired sub-object.
