The g++ demangler is called c++filt.

The expression

__doapl__H1Zd_Pt7complex1ZX01RCt7complex1ZX01_Rt7complex1ZX01

demangles to

complex<double> & __doapl<double>(complex<double> *, complex<double> const &)

and

  sqr__H1ZQ25blitzt5Array2Zt7complex1Zdi1__5blitzRCt6ETBase1ZX01_Q
  25blitzt13_bz_ArrayExpr1ZQ25blitzt20_bz_ArrayExprUnaryOp2ZQ35blitzt6asExpr1ZX016
  T_exprZQ25blitzt7_bz_sqr1ZQ45blitzt6asExpr1ZX016T_expr9T_numtype

demangles to

  blitz::_bz_ArrayExpr<blitz::_bz_ArrayExprUnaryOp
  <blitz::asExpr<blitz::Array<complex<double>, 1> >::
  ::T_expr, blitz::_bz_sqr<blitz::
  asExpr<blitz::Array<complex<double>, 1> >::
  T_expr::T_numtype> > > blitz sqr<blitz::Array<complex<double>, 1> >
