            Bug ID: 137785
           Summary: JavaScript Control Flow Profiler
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: saambarati1 at gmail.com

JavaScriptCore should know which basic blocks have executed. If it knows this information, it allows the web inspector to ask it such questions and create a UI around this feature.
This also works really nicely with type profiling because it disambiguates missing type annotations for basic blocks that haven't executed.
