[Bug debug/39706] New: namespaces represented incorrectly in debug_pubnames

[tromey at gcc dot gnu dot org]

Compile this with -g:

namespace x { int x; }
class y { public: static int x; };
int y::x;
int main() { return x::x; }

Now examine the debug_pubnames section with readelf.  I see:

    70                  main
    119                 x
    130                 y::x

However, I expected "x::x"; "y::x" seems correct.

The dwarf spec is a bit weird here:

>     In the case of the name of a function member or static data member
>     of a C++ structure, class or union, the name presented in the
>     .debug_pubnames section is not the simple name given by the
>     DW_AT_name attribute of the referenced debugging entry, but rather
>     the fully qualified name of the data or function member.

It doesn't mention namespaces.  However, this is not very useful;
and perhaps this text is not normative.
