bsi_for_stmt(current_function_decl); does not seems correct to me
as it should return the function's declaration's basic block
iterator; which does not belongs to bb.
I think you are also missing some statement to get the current
tree node in the loop:
tree stmt = bsi_stmt (bsi);
and later recursively manipulate it with walk_tree ().
Please look how it is done in cgraph_create_edges().
