# This file is part of the gdb testsuite.

# This contains tests for GDB's use of RTTI information.  This stems

# from a bug reported in PR gdb/488 and other places, which leads to

# statements like 'warning: can't find class named 'C::D', as given by

# C++ RTTI'.  It arises from GDB not knowing about classes that are

# defined in namespaces.

# NOTE: carlton/2003-05-16: I suspect it could arise from nested class

# issues, too, and even once we fix that, there might be situations

# (involving templates, in particular) where this problem triggers

# because GDB and GCC have different ideas what a class is called.
