           Summary: CTI refactoring: remove m_callFrame; batch JIT all
                    static trampolines.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: barraclough at apple.com


Batch compile the set of static trampolines at the point Machine is
constructed, using a single allocation.

Refactor out m_callFrame from CTI, since this is only needed to access the
global data (instead store a pointer to the global data directly, since this is
available at the point the Machine is constructed).

Add a method to align the code buffer, to allow JIT generation for multiple
trampolines in one block.
