question: private void adjustBCIndex ( Instruction barrier ) { NormalMethod source = barrier . position ( ) . method ; if ( source . isForOsrSpecialization ( ) ) { barrier . adjustBytecodeIndex ( - source . getOsrPrologueLength ( ) ) ; } }
target:  The OsrBarrier instruction is not in IR, so the bc index was not adjusted in OSR_AdjustBCIndex.
