| 30 // problem 1 | |
| 31 // the conversions in TernaryNode are not necessary, but they should not cause problems. They did | |
| 32 // this was because the result of Global.allocate(Object[])Object which returns a NativeObject. | |
| 33 // was tracked as an object type on our stack. The type system did not recognize this as an array. | |
| 34 // Then the explicit conversions became "convert NativeArray->Object[]" which is a checkccast Object[] | |
| 35 // which naturally failed. | |
| 36 | |
| 37 // I pushed the appropriate arraytype on the stack for Global.allocate. | |
| 38 | |
| 39 // I also removed the conversions in CodeGen, all conversions should be done in Lower, as | |
| 40 // NASHORN-706 states. | |

| 45 // This made the test pass, but it's still not correct to pick widest types for array | |
| 46 // and primitives. Widest(Object[], int) gave us Object[] which makes no sense. This is used | |
| 47 // by lower to type the conversions, so function b below also failed until I made a change | |
| 48 // ty type widest to actually return the widest common denominator, if both aren't arrays | |
