%% Purpose : Contains typed record declarations for the CFG data structures
%%
%% $Id$
%%============================================================================
-type cfg_lbl() :: non_neg_integer().
%%
%% This is supposed to be local but appears here for the time being
%% just so that it is used below
%%
-record(cfg_info, {'fun' :: mfa(),
start_label :: cfg_lbl(),
is_closure :: boolean(),
closure_arity :: arity(),
is_leaf :: boolean(),
params, % :: list()
info = []}). %% this field seems not needed; take out??
%%
%% Data is a triple with a dict of constants, a list of labels and an integer
%%
-type cfg_data() :: {dict:dict(), [cfg_lbl()], non_neg_integer()}.
%%
%% The following is to be used by other modules
%%
-record(cfg, {table = gb_trees:empty() :: gb_trees:tree(),
info :: #cfg_info{},
data :: cfg_data()}).
-type cfg() :: #cfg{}.
