      Description

      The current JVMPI specifies COMPILE_METOD_LOAD to provide PC to source
      line mapping. The actual implementation rarely generates such a mapping and
      even when it does, its quality is quite low. It is believed that the dynamic
      compiler should rather provide PC to byte-code index mapping and leave the rest
      to profiling tools, which should map available information to source lines
      using line number information from class files.
