The demangling code is in -liberty. Check out demangle.h in the gcc or
binutils sources.

The squangling is really a superset of standard mangling, so there is
no need to distinguish (with a few exceptions, in which case the
demangler gets it wrong).

You may also want to look at gxxint.texi, which documents the
mangling.
