Ah, okay. I was worried that it had something to do with abstract
declarations of classes; there, we certainly need the namespace DIE.

I'm not sure I quite understand this. Say we have
namespace N {
inline void funcToInline() {}
}
namespace M {
void f() {
funcToInline();
}
}
Then what does the debug info look like? I just want to make sure
that, in a mythical version of GDB that can actually deal with inlined
functions, 'break N::funcToInline' will still work.
