How to access AST for a given .cpp file after it is parsed by cp/parser.cc ? Looking at struct cp_parser, there are several tree fields, but none of them seem to correspond to the AST. None of the functions downstream from parse_file() seem to access any object that would resemble AST. So I have trouble locating where the constructed AST is stored. I would like to traverse the AST to do some minor modifications, like setting unassigned pointers to NULL, checking bounds for pointer arithmetics in expressions like (x+n), preventing pointer casts to (long int), preventing pointer casts ( or checking object alignment, to ensure consistency of pointer cast) and the like, for which AST seems like the place to do these alterations. Thanks, schw
