1107145 - Separate TypeDescr and TypedProto

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Description

[Brian Hackett [Laid off!]]

Attachment: patch

Currently type descriptors and typed object prototypes are 1:1.  In order to support arrays of different lengths having the same prototype, this needs to be fixed.  The attached patch moves type descriptor pointers from the prototype to the typed object's type object (bleah) itself.  The actual sharing of prototypes for typed object arrays will happen in another patch.
