            Bug ID: 152347
           Summary: Improve JSObject::put performance
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: fpizlo at apple.com

The JSObject::put code used to be fast, and then we made it slow by incrementally adding stuff to it, like hooks for immutability inference and property type inference.

This bug is about recovering some of that lost performance.
