The DWARF spec does not say anything about normalizing the fully qualified
names in .debug_pubnames:
"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 information entry, but rather the fully qualified
name of the data or function member. "
My first thought is to add the 'no-space' rule for the qualified name, but
I do realize that there are some C++ names that requires the additional
space. (i.e. std::vector<std::list<int> >) [This space is no longer
required in C++0x]. Perhaps the rules should be: "In the case the
qualified name has multiple spellings, the one with the shortest spelling
should be used." Any thoughts?
