--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
Final value replacement has
(set_scalar_evolution
instantiated_below = 5
(scalar = sum_7)
(scalar_evolution = {0, +, {1, +, 1}_1}_1))
)
(chrec_apply
(varying_loop = 1
)
(chrec = {0, +, {1, +, 1}_1}_1)
(x = (unsigned int) max_value_4(D) + 4294967295)
(res = scev_not_known))
not replacing:
sum_1 = PHI <sum_7(3)>
because it doesn't know this (IIRC there's a duplicate bug where I tried some
things to handle this).
