           Summary: Fix sampling counters on ARMv7, move add64
                    functionality to macro assembler
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: barraclough at apple.com


The ability to add an integer to a uint64_t in memory is poorly copied in multiple places & ifdef'ed on architecture, addWithCarry32 is also a badly designed interface since add32 is not required to set flags (we have no concept of flags in the macro assembler interface).
