| 2776 | * if "bmap" already contains upper bounds on "div" as the newly |
| 2777 | * introduce lower bounds can then be combined with the pre-existing |
| 2778 | * upper bounds. Similarly for upper bounds. |
| 2779 | * We therefore first check if "bmap" contains any lower and/or upper bounds |
| 2780 | * on "div". |
| 2781 | * |
| 2782 | * It is interesting to note that the introduction of these constraints |
| 2783 | * can indeed lead to more accurate results, even when compared to |
| 2784 | * deriving constraints on the argument of "div" from constraints on "div". |
| 2785 | * Consider, for example, the set |
| 2786 | * |
| 2787 | * { [i,j,k] : 3 + i + 2j >= 0 and 2 * [(i+2j)/4] <= k } |
| 2788 | * |
| 2789 | * The second constraint can be rewritten as |
| 2790 | * |
| 2791 | * 2 * [(-i-2j+3)/4] + k >= 0 |
| 2792 | * |
| 2793 | * from which we can derive |
| 2794 | * |
| 2795 | * -i - 2j + 3 >= -2k |
| 2796 | * |
| 2797 | * or |
| 2798 | * |
| 2799 | * i + 2j <= 3 + 2k |
| 2800 | * |
| 2801 | * Combined with the first constraint, we obtain |
| 2802 | * |
| 2803 | * -3 <= 3 + 2k or k >= -3 |
| 2804 | * |
| 2805 | * If, on the other hand we derive a constraint on [(i+2j)/4] from |
| 2806 | * the first constraint, we obtain |
| 2807 | * |
| 2808 | * [(i + 2j)/4] >= [-3/4] = -1 |
| 2809 | * |
| 2810 | * Combining this constraint with the second constraint, we obtain |
| 2811 | * |
| 2812 | * k >= -2 |
