This one is also probably an overflow in Omega,
but the dependence problem looks pretty simple...
This occurs in gcc/gcc/omega.c on amd64-linux.
Dist vectors from the first dependence analyzer:
1 1 0
Omega dist vectors are not the same:
0 10922 10922
Data dependence relation is:
(Data Dep:
access_fn_A: {1, +, 1}_7
access_fn_B: {1, +, 1}_7
(subscript
iterations_that_access_an_element_twice_in_A: 0
last_conflict: scev_not_known;
iterations_that_access_an_element_twice_in_B: 0
last_conflict: scev_not_known;
(Subscript distance: 0
)
)
distance_vect: 0 10922 10922
direction_vect: = + +
)
