Hi Revital, Thank you very much.. This is very helpful. I was about to lost myself in the code. I will try to experiment with your advices.
Also, having the opportunity, I would like to ask you if there is any function to use for deleting a tree (most particularly a statement or variable declaration tree) or it would be enough to assign it as NULL (which does not seems to be a gentle solution).

You can access the function's tree through it's call-graph node. (the call-graph node has a pointer to the function's tree declaration), than use block_stmt_iterator (bsi) to iterate through the function's basic blocks; each statement in the basic block can be recursively traversed via walk_tree () function. (see cgraph_create_edges () in cgraphunit.c). build1 () function (tree.h) can be used to construct a new tree node. Hope it helps, Revital
