Currently, in expand_dereference(), the dereference of a symbol with a complex type is considered as costing as high as a non-symbol because it's not recognised it's a symbol. However, both cases should have exactly the same cost since they address calculation amounts to 'symbol + offset'. So, instead of taking in account a single level of symbol + offset let's use a loop for this in order to handle symbol [+ offset]* Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@gmail.com>
