| aoqi@0 | 30 | // problem 1 |
| aoqi@0 | 31 | // the conversions in TernaryNode are not necessary, but they should not cause problems. They did |
| attila@962 | 32 | // this was because the result of Global.allocate(Object[])Object which returns a NativeObject. |
| attila@962 | 33 | // was tracked as an object type on our stack. The type system did not recognize this as an array. |
| aoqi@0 | 34 | // Then the explicit conversions became "convert NativeArray->Object[]" which is a checkccast Object[] |
| aoqi@0 | 35 | // which naturally failed. |
| aoqi@0 | 36 | |
| aoqi@0 | 37 | // I pushed the appropriate arraytype on the stack for Global.allocate. |
| aoqi@0 | 38 | |
| aoqi@0 | 39 | // I also removed the conversions in CodeGen, all conversions should be done in Lower, as |
| aoqi@0 | 40 | // NASHORN-706 states. |

| aoqi@0 | 46 | // and primitives. Widest(Object[], int) gave us Object[] which makes no sense. This is used |
| aoqi@0 | 47 | // by lower to type the conversions, so function b below also failed until I made a change |
