// 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.

// 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
