hi all

thanx for ur help till now :)

-what i want is this
    To construct a CFG corresponding to the parse tree "ruby_eval_tree", 
the discription is as follows:
       it contains a node corresponding to every statement
       in every node all the variables used in that statement is stored
       the type information corresponding to every variable is also stored

- what i ve done till now is this
    i ve collected the variables and stored them in the nodes 
corresponding to each statement.

a variable can be indexed using "ruby_scope->local_vars[node->nd_cnt]"
i tried to apply TYPE and CLASS_OF on this but it is giving same value 
for all the variables no matter what type of the object it is holding

i tried to trace how it finds the correct method to call .. it is using 
the same CLASS_OF function to get the type and index it into the method 
table

dont know what to do :(
