We are building scalar evolutions that have no defined semantics:
the initial value is variating in an inner loop.
{(2 + (integer(kind=4)) {0, +, 1}_5) * 5 + ((2 + (integer(kind=4)) {0, +, 1}_4)
+ -6), +, 6}_1
and

We build these scevs because chrec_fold_multiply and chrec_fold_plus
do not correctly handle conversions: op0 = (integer(kind=4)) {0, +, 1}_4
is considered non variating in any loop, and thus when op0 gets added to

Hi Reza,
In the Graphite branch, we insert in the scop context the bounds on the
parameter kk due to the type of kk:

It seems like the problem is in the overly conservative implementation
of add_param_constraints, as we do not insert bounds for pointers:
if (!INTEGRAL_TYPE_P (type))
return;
and in the original testcase we
