            Bug ID: 240881
           Summary: Use the Clang .alt_entry directive to allow use of
                    global labels in LLInt asm.
           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

With this, debugging LLInt code will be easier.  LLInt code will no longer all be at an offset from vmEntryToJavaScript.  They will instead be broken up into different sections under human readable labels.

Secondly, crash traces of LLInt crashes will now be able to tell us give us the nearest label, as opposed to everything being an offset from vmEntryToJavaScript.
