Refresh the implementation of Symbols to catch up with what the specification now mandates: * The global Symbol() function manufactures new Symbol values, optionally with a string description attached. * Invoking Symbol() as a constructor will now throw. * ToString() over Symbol values still throws, and Object.prototype.toString() stringifies like before. * A Symbol value is wrapped in a Symbol object either implicitly if it is the receiver, or explicitly done via Object(symbolValue) or (new Object(symbolValue).) * The Symbol.prototype.toString() method no longer throws on Symbol wrapper objects (nor Symbol values.) Ditto for Symbol.prototype.valueOf(). * Symbol.prototype.toString() stringifies as "Symbol("<description>"), valueOf() returns the wrapper's Symbol value. * ToPrimitive() over Symbol wrapper objects now throws. Overall, this provides a stricter separation between Symbol values and wrapper objects than before, and the explicit fetching out of the description (nee name) via the "name" property is no longer supported (by the spec nor the implementation.) Adjusted existing Symbol test files to fit current, adding some extra tests for new/changed behavior.

|
|
// activations. When enough activations have been created an exception is
|
|
// thrown and we check that the right activation catches the exception and that
|
|
// no other activations do. The right activation is always the topmost one with
|
|
// a handler, regardless of whether it is in JavaScript or C.
|
|
//
|
|
// The notation used to describe a test case looks like this:
|

//
|

// *JS[4] *C[3] @JS[2] C[1] JS[0]
|

//

// level. Stars identify activations with exception handlers, the @ identifies
|
|
// the exception handler that should catch the exception.
|
|
//
|
|
// BUG(271): Some of the exception propagation does not work on the
|
|
// ARM simulator because the simulator separates the C++ stack and the
|
|
// JS stack. This test therefore fails on the simulator. The test is

|
// not threaded to allow the threading tests to run on the simulator.
