def attach_function(name, func, args, returns = nil, options = nil)
  mname, cname, arg_types, ret_type, options = convert_attach_function_params(name, func, args, returns, options)
  function_handle = find_function_handle(cname, arg_types)
  attach_function_handle(function_handle, mname, arg_types, ret_type, options)
end

#attach_llvm_jit_function(name, func, args, returns = nil, options = nil) ⇒ Object

Same as attach_function, but raises an exception if cannot create JIT function instead of falling back to the regular FFI function
