; In this test we check how heuristics for complete unrolling work. We have
; three knobs:
; 1) -unroll-threshold
-; 2) -unroll-absolute-threshold and
-; 3) -unroll-percent-of-optimized-for-complete-unroll
+; 3) -unroll-percent-dynamic-cost-saved-threshold and
+; 2) -unroll-dynamic-cost-savings-discount
;
; They control loop-unrolling according to the following rules:
; * If size of unrolled loop exceeds the absoulte threshold, we don't unroll
; optimizations to remove ~55% of the instructions, the loop body size is 9,
; and unrolled size is 65.

; percent of instructions, we shouldn't unroll:
