g++ doesn't currently generate those, but I would like to change that 
(c++/2316). And nothing prevents another compiler from actually 
implementing the itanium C++ ABI (this code is mostly for binutils if I 
understand correctly).

I thought it made sense to submit independent pieces first, but if it is 
preferable to wait until everything is ready (not soon) I understand.

Hey, that looks nice!

It doesn't look like attributes (in double square brackets) get mangled, 
so it shouldn't look strange (and it could always be changed in that 
case).
