Remove all of the Tru64 specific stuff from the base System object
into its own Tru64System object. Also remove the System builder stuff and create a Tru64System builder. This makes it much simpler to support more operating systems. arch/alpha/ev5.cc: Each system provides its own mechanism for doing a breakpoint. base/remote_gdb.hh: #include <map> cpu/pc_event.cc: cpu/pc_event.hh: Separate out System specific PCEvents cpu/simple_cpu/simple_cpu.cc: each system provides its own init script kern/tru64/dump_mbuf.cc: kern/tru64/printf.cc: Stick this in a namespace --HG-- extra : convert_revision : 9f74527ed2ff8010431d9aff34357aaecc1fb3f6
