Hi,

I noticed dwarf_name is mapped to decl_printable_name for C++ and we can gain another xstrdup/free if we implement the dwarf_name langhook for C++ by simply using cp/error.c:lang_decl_name. This way we avoid using the cxx_printable_name ring buffer for function decls.

Yes, that's possible.

Ciao, Michael.
