In the last chunk z900 can be used instead of zarch. The splitters are guarded with TARGET_CPU_ZARCH. This requires a zarch cpu but it does not need to run in zarch mode. z900 is the first zarch cpu. Ok with that change. Many thanks for doing the migration. We'll try to do a performance regression run soon. Bye, -Andreas-
