            Bug ID: 140804
           Summary: If we inline a nested function call, we should be able
                    to do GCSE on closure variable accesses and object
                    allocation sinking on the activation
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (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

I'm pretty sure that this won't work right now because we don't reason about the activation that a NewFunction* operation references.  But we totally should do this.

This would be a poor man's way of doing single-and-loving-it analysis: http://www.cs.purdue.edu/homes/suresh/papers/popl98.ps.gz
