           Summary: Predicted types should know about arguments

           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2

        ReportedBy: fpizlo at apple.com


And they should be able to distinguish between the arguments from the current frame and arguments from other frames.  Value profiling can't distinguish that, but prediction propagation and CFA can.

Patch forthcoming.
