// This file holds platform-independent bodies of inline functions for frames.

// Note: The bcx usually contains the bcp; however during GC it contains the bci
//       (changed by gc_prologue() and gc_epilogue()) to be Method* 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).
