           Summary: CSS JIT: remove JumpToClearAdjacentTail
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: utatane.tea at gmail.com


Since adjacent backtracking stack reference is pre-allocated
in prologue in http://trac.webkit.org/changeset/166834,
clearing stack phase is not needed. So we can drop
JumpToClearAdjacentTail from backtracking action and simplify
backtracking handling.
