            Bug ID: 232172
           Summary: Change Heap::writeBarrier() to do the cheaper check
                    first.
           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: mark.lam at apple.com

It's cheaper to do a check using incoming args (which are already loaded in registers) than to do a check which requires memory loads.
