            Bug ID: 156555
           Summary: PolymorphicAccess should try to generate a stub only
                    once
    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

Currently, we don't do any buffering of access cases prior to the first stub generation.  We only enable it after a stub has been generated.

I implemented buffering that way to be conservative.  Now we should push it further and always buffer.  The outcome ought to be that most ICs only generate a stub once.
