Hi, I have some problems for translating calls to unbound methods. Let's show with an example: class MyClass: def __init__(self, x): self.x = x class MyDerivedClass(MyClass): def __init__(self, x): MyClass.__init__(self, x) During rtyping the field and method names are mangled, so the __init__ method became something like 'o__init____variant0': as long as I call bound methods this is not a problem because the low-level op oosend contains the right mangled name, but difficult arises when I try to call an unbound method such as the one showed above; the low-level op that I obtain is this: v9 = direct_call((<pypy.rpython.ootypesystem.ootype._static_meth object at 0xb78e51ac>), self_1, x_2) Let 'x = op.args[0].value': (Pdb) x._name 'Base.__init__' (Pdb) x.graph.name 'Base.__init__' As you can see I can read only the original unmangled name, but it is useless because I've to deal with the mangled one. I've tried to search around for a place where to read that but I couldn't find it. How can I do? thanks for the help ciao Anto
