            Bug ID: 251667
           Summary: Implement a more accurate currentStackPointer().
           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

currentStackPointer() was already accurate for some ports (the ones that support inline assembly), but for others and when using a Debug build, we fall back to a C runtime function that only gives an approximate value.  This patch implements a currentStackPointer() that is accurate for all currently support ports even when using a Debug build.
