Solve the following python programming problem given the following code:
def configure_project(self) : 
    '
        Configure the project to set up global settings (like SimProcedures).
        ' 
    self.continue_addr = self.proj._extern_obj.get_pseudo_addr ('angr##simproc_continue') 
    self.proj.hook (self.continue_addr, SimProcedureContinuation) 
    def irelative_resolver(resolver_addr) : 
        resolver = self.proj.factory.callable (resolver_addr, concrete_only = True) 
        try : 
            val = resolver () 
except AngrCallableError : 
            l.error ('Resolver at %#x failed to resolve!', resolver_addr) 
            return None 
if (not val.singlevalued) : 
            l.error ('Resolver at %#x failed to resolve! (multivalued)', resolver_addr) 
            return None 
return val._model_concrete.value 
self.proj.loader.perform_irelative_relocs (<MASK>) 
    
    Given the code above, what is a proper replacement for <MASK>? Choose among: self
