Looks like gdb and lldb both have issues with C++ local types (either types defined in anonymous namespaces, or otherwise localized - eg: a non-local template with a local type or variable in one of its parameters). GDB correctly associates directly referenced types (eg: the type of a variable doesn't get confused just because there's a same-named-but-distinct type in another CU) where LLDB does not (gets that correct for a type in an anonymous namespace, but not a template that's made local via a local-typed parameter). Neither debugger then handles overload resolution and can correctly identify that a function taking that parameter type from another CU is not a valid overload candidate for this type.
So... what could/should we do about this? In theory, using DW_AT_external for non-local types would be consistent with other DWARF usage, but then a consumer would have to assume that all non-external types are distinct, which probably isn't the right default given current deployments? Mandating this in DWARFv6 might be possible? _______________________________________________ Dwarf-Discuss mailing list Dwarf-Discuss@lists.dwarfstd.org http://lists.dwarfstd.org/listinfo.cgi/dwarf-discuss-dwarfstd.org
