            Bug ID: 151531
           Summary: FTL lowering should tell B3 the right block
                    frequencies
    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

B3 would be happiest with the block frequency being just the execution count of the DFG block of the current node, and just "1" for any blocks that didn't result from lowering.
