            Bug ID: 149823
           Summary: GC should be more aggressive about canceling plans
                    that will be DOA
    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 GC used to be able to cancel FTL plans if the profiled DFG CodeBlock was going to be jettisoned.  Then, we regressed that code and made it so that GC canceled all FTL plans.  Then we removed the code to cancel FTL plans, except in cases where the owning executable was dead.

It might be worthwhile to bring some of that code back somehow.
