Why would they not have a mangled name?
Interesting. What do they look like, and in what context do they
appear?
Anywhere you need a name for linkage purposes, such as in a function
signature, or as a template argument of another type, or in the
std::type_info::name() for the type etc. etc.
$ g++ -o test.o -c -x c++ - <<< 'struct X {}; void f(X) {}
template<typename T> struct Y { }; void g(Y<X>) {}' && nm
--defined-only test.o
0000000000000000 T _Z1f1X
0000000000000007 T _Z1g1YI1XE
The mangled name for X is "X" and the mangled name for Y<X> is "YI1XE"
which includes the name "X".
This isn't really on-topic for solving the GDB type lookup problem
though.
Ah ok, the class name appears mangled in other entities' mangled name.
But from what I understand there's no mangled name for the class such
that
echo <class mangled name> | c++filt
outputs the class name (e.g. "Foo<10>"). That wouldn't make sense,
since there's no symbol for the class itself.
