            Bug ID: 176868
           Summary: [JSC] Investigate DFG inlining for six-speed
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: utatane.tea at gmail.com

Basically this test is super slow because the target function is not inlined.
But, this should be somewhat inlined by poly inlining / simple inlining with cleared stub.

It seems that our CallSiteInfo is cleared. And non-poly function is set for that.
But it has badFunction in exit site data, and poly stub is already cleared.
So it always has couldTakeSlowPath = true.

I'm not sure this is the right behavior for this case. I think we should have a good story to handle the above case well.
