Use ssizetype when long_long_integer_type_node is NULL.
2010-03-11 Sebastian Pop <sebastian.pop@amd.com>
* graphite-clast-to-gimple.c (my_long_long): Defined.
(gcc_type_for_cloog_iv): Use it instead of long_long_integer_type_node.
* graphite-sese-to-poly.c (my_long_long): Defined.
(scop_ivs_can_be_represented): Use it.
