            Bug ID: 213498
           Summary: We should have a JSON.parse bytecode
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: keith_miller at apple.com

If a script has a very large JSON payload we currently allocate bytecode to initialize the object proportionally to the size of the object. This is very inefficient since most JSON massive objects are only initialized once. Instead, we should have a bytecode that takes a source position to parse as JSON.
