           Summary: Don't try to optimize huge code blocks
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fpizlo at apple.com


Huge code blocks are expensive to optimize.  It's probably unwise for a production VM to try to do full optimizations on code blocks that are gigantic, since in the worst case this is probably more expensive than not doing any optimizations.  As well, giant code blocks are much more likely to be initializers of some kind rather than containing hot code.
