16 | # This file is part of the gdb testsuite. | |
17 | ||
18 | # This contains tests for GDB's use of RTTI information. This stems | |
19 | # from a bug reported in PR gdb/488 and other places, which leads to | |
20 | # statements like 'warning: can't find class named 'C::D', as given by | |
21 | # C++ RTTI'. It arises from GDB not knowing about classes that are | |
22 | # defined in namespaces. | |
23 | ||
24 | # NOTE: carlton/2003-05-16: I suspect it could arise from nested class | |
25 | # issues, too, and even once we fix that, there might be situations | |
26 | # (involving templates, in particular) where this problem triggers | |
27 | # because GDB and GCC have different ideas what a class is called. | |
