Seems to work for me. Any details on the architecture you tested on?

Ok, it's a HWI 32 issue then. The caller should use host_integerp () on the
tree before calling int_cst_value.

------- Comment #4 from rguenth at gcc dot gnu dot org 2007-03-15 13:44 -------
Uh:
static void
gather_interchange_stats (VEC (ddr_p, heap) *dependence_relations,
VEC (data_reference_p, heap) *datarefs,
struct loop *loop,
struct loop *first_loop,
unsigned int *dependence_steps,
unsigned int *nb_deps_not_carried_by_loop,
unsigned int *access_strides)
{
...
(*access_strides) +=
int_cst_value (array_size) * int_cst_value (tstride);
nonono, int_cst_value returns a HOST_WIDE_INT, you cannot store that into
an unsigned int. Also int_cst_value does ICE if array_size's type doesn't
fit a HOST_WIDE_INT. There is host_integerp () to verify if a tree int
fits HOST_WIDE_INT.
