------- Comment #25 from pinskia at gcc dot gnu dot org  2006-11-08 03:35 -------
(In reply to comment #24)
> Does anyone know why var above was marked as

Yes because it is an compiler generated decl for the load of the global.  The
main reason why we don't mark the RTL for artifical decls is because we get
still like:
(int*)int_var
Which causes problem.  This is what PTR_PLUS_EXPR which I am creating helps
solves.
