           Summary: LLINT loadisFromInstruction doesn't need special case
                    for big endians
           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

The change introduced in r167076 was wrong. We cannot apply the offset adjustment on every loadisFromInstruction usage as the instruction (UnlinkedInstruction) is declared as an union (i.e. with the int32_t operand variable). The offset of the union members will be the same as the offset of the first one, that is 0. The behavior here is the same on little and big endian architectures us we don't need special case for big endians.
