Probably not.

C++ allows you to overload functions by their parameter type.

   eg:

    double foobar ( int    param ) { ... }
    double foobar ( double param ) { ... }

...but it doesn't allow you to overload them by their return type.

   eg

    double foobar ( int param ) { ... }
    int    foobar ( int param ) { ... }  /* Illegal */

...hence there is no need to store the return type in the symbol table
and therefore there is no way to determine it from the mangled name.
