--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
I'm talking about
(compute_affine_dependence
stmt_a: _5 = a1[i_16];
stmt_b: MASK_STORE (_34, 0B, _ifc__32, _9);
) -> dependence analysis failed
somehow it works for
(compute_affine_dependence
stmt_a: _8 = MASK_LOAD (_33, 0B, _ifc__32);
stmt_b: MASK_STORE (_35, 0B, _ifc__36, _11);
(analyze_overlapping_iterations
(chrec_a = {0B, +, 4}_1)
(chrec_b = {0B, +, 4}_1)
(overlap_iterations_a = [0])
(overlap_iterations_b = [0]))
)
