60// Note: The bcx usually contains the bcp; however during GC it contains the bci
61//       (changed by gc_prologue() and gc_epilogue()) to be methodOop position
62//       independent. These accessors make sure the correct value is returned
63//       by testing the range of the bcx value. bcp's are guaranteed to be above
64//       max_method_code_size, since methods are always allocated in OldSpace and
65//       Eden is allocated before OldSpace.
66//
67//       The bcp is accessed sometimes during GC for ArgumentDescriptors; than
68//       the correct translation has to be performed (was bug).
