           Summary: Move call linking / repatching down from
                    AbstractMacroAssembler into MacroAssemblerARCH
                    classes.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        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


This allows the implementation to be defined per architecture.  Specifically
this addresses the fact that x86-64 MacroAssembler implements far calls as a
load to register, followed by a call to register.  Patching the call actually
requires the pointer load to be patched, rather than the call to be patched. 
This is implementation detail specific to MacroAssemblerX86_64, and as such is
best handled there.
