10 | * Remark : |
11 | 1. This source code is modified to unify the formats of the benchmark |
12 | programs in CHStone. |
13 | 2. Test vectors are added for CHStone. |
14 | 3. If "main_result" is 0 at the end of the program, the program is |
15 | correctly executed. |
16 | 4. Please follow the copyright of each benchmark program. |
