            Bug ID: 203942
           Summary: Remove remnants of support code for an upwards growing
                    stack.
           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

We haven't supported an upwards growing stack in years, and a lot of code has since been written specifically with only a downwards growing stack in mind (e.g. the LLInt, the JITs).  Also, all our currently supported platforms use a downward growing stack.

We should remove the remnants of support code for an upwards growing stack.  The presence of that code is deceptive in that it conveys support for an upwards growing stack where this hasn't been the case in years.
