In such case I will add it, it should be there.
It probably doesn't hurt, but it also isn't a real/proper mangling
scheme. Just an g++ convention. It "demangles" to 'global constructors
keyed to xxx'. According to the documentation the only prefix you should
check for is _Z:
http://mentorembedded.github.io/cxx-abi/abi.html#demangler
If the user has a set of external names to demangle, they should
check that the names are in fact mangled (that is, begin with
"_Z") before passing them to __cxa_demangle.
