    • We don't expect that anybody has ever enabled one of these flags because it doesn't make sense at all.

      Summary

      Remove PPC64 platform flags "UsePower6SchedulerPPC64" and "InsertEndGroupPPC64".

      Problem

      The PPC64 platform flags "UsePower6SchedulerPPC64" and "InsertEndGroupPPC64" should never have been added to the OpenJDK. There was never any functionality behind them.

      Solution

      Remove them from globals_ppc.hpp.

      Specification

      Remove (expire) the following flags:

      product(bool, UsePower6SchedulerPPC64, false, "Use Power6 Scheduler.") product(bool, InsertEndGroupPPC64, false, "Insert EndGroup instructions to optimize for Power6.")
