| # 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. |
