Here's another testcase:
subroutine sub(aa,bb,n,m)
implicit none
integer, intent(in) :: n,m
real, intent(inout) :: aa(n,m)
real, intent(in) :: bb(n,m)
integer :: i,j
do j= 2,n
do i = 1,m
aa(i,j)= aa(i,j-1)+bb(i,j-1)
enddo
enddo
end subroutine
end
Here too we get:
(compute_affine_dependence
(stmt_a =
D.1385_55 = (*aa_54(D))[D.1384_53])
(stmt_b =
(*aa_54(D))[D.1380_49] = D.1390_62)
(subscript_dependence_tester
(analyze_overlapping_iterations
(chrec_a = {pretmp.34_76 + 1, +, 1}_2)
(chrec_b = {pretmp.34_32 + 1, +, 1}_2)
(analyze_siv_subscript
siv test failed: unimplemented.
)
(overlap_iterations_a = not known
)
(overlap_iterations_b = not known
)
)
(dependence classified: scev_not_known)
)
)
