 ; CHECK: remark: no_fpmath.c:6:14: loop not vectorized
-; CHECK: remark: no_fpmath.c:17:14: vectorized loop (vectorization width: 2, interleaved count: 2) (hotness: 300)
+; CHECK: remark: no_fpmath.c:17:14: vectorized loop (vectorization width: 2, interleaved count: 1) (hotness: 300)
 
----------------
according to profile original loop has 99 iterations thus interleaving is disabled by short trip count heuristics controlled by tiny-trip-count-interleave-threshold
