| // problem 1 |
| // the conversions in TernaryNode are not necessary, but they should not cause problems. They did |
| // this was because the result of Global.allocate(Object[])Object which returns a NativeObject. |
| // was tracked as an object type on our stack. The type system did not recognize this as an array. |
| // Then the explicit conversions became "convert NativeArray->Object[]" which is a checkccast Object[] |
| // which naturally failed. |
| |
| // I pushed the appropriate arraytype on the stack for Global.allocate. |
| |
| // I also removed the conversions in CodeGen, all conversions should be done in Lower, as |
| // NASHORN-706 states. |
| |
| var silent = false; |
| var stdio = silent ? ['pipe', 'pipe', 'pipe', 'ipc'] : [0, 1, 2, 'ipc']; |
| |
| // This made the test pass, but it's still not correct to pick widest types for array |
| // and primitives. Widest(Object[], int) gave us Object[] which makes no sense. This is used |
| // by lower to type the conversions, so function b below also failed until I made a change |
| // ty type widest to actually return the widest common denominator, if both aren't arrays |
