| michael@0 | 1 | // IM has the following fastpaths: |
| michael@0 | 2 | // - constant index (constant) |
| michael@0 | 3 | // - need negative int check (neg) |
| michael@0 | 4 | // - needs hole check (hole) |
| michael@0 | 5 | // So to test everything we have to do: |
| michael@0 | 6 | // constant | neg | hole |
| michael@0 | 7 | // test 1: 0 0 0 |
| michael@0 | 8 | // test 2: 1 0 0 |
| michael@0 | 9 | // test 3: 0 1 0 |
| michael@0 | 10 | // test 4: 1 1 0 |
| michael@0 | 11 | // test 5: 0 0 1 |
| michael@0 | 12 | // test 6: 1 0 1 |
| michael@0 | 13 | // test 7: 0 1 1 |
| michael@0 | 14 | // test 8: 1 1 1 |
