984090 - PJS: Create parallel version of MNewDerivedTypedObject

Status: RESOLVED WONTFIX

(Core :: JavaScript Engine: JIT, defect)

Description

[Niko Matsakis [:nmatsakis]]

There is no particular reason that we can't allocate typed objects in parallel code, except that it hasn't been implemented yet. At minimum, we should implement the NewDerivedTypedObject path. This would obviate the need for a hacky solution to bug 983897.

(Still, it may be wise not to hurry. One reason though that I've held off on implementing parallel versions of these paths is that I expect to make some changes to the details of the typed object implementation, and the more optimized paths that exist the more updating that will be needed.)
