//       (changed by gc_prologue() and gc_epilogue()) to be methodOop position

//       independent. These accessors make sure the correct value is returned

//       by testing the range of the bcx value. bcp's are guaranteed to be above

//       max_method_code_size, since methods are always allocated in OldSpace and

//       Eden is allocated before OldSpace.

//

//       The bcp is accessed sometimes during GC for ArgumentDescriptors; than

//       the correct translation has to be performed (was bug).
