Separate the stuff for SimObject from SimObject builder.
This makes testing a bit easier. arch/alpha/alpha_memory.cc: cpu/intr_control.cc: cpu/memtest/memtest.cc: cpu/simple_cpu/simple_cpu.cc: dev/alpha_console.cc: dev/console.cc: dev/disk_image.cc: dev/etherbus.cc: dev/etherdump.cc: dev/etherlink.cc: dev/ethertap.cc: dev/simple_disk.cc: kern/tru64/tru64_system.cc: sim/main.cc: sim/prog.cc: Need to include builder.hh sort #includes sim/sim_object.cc: sim/sim_object.hh: Separate the SimObjectBuilder stuff into its own file --HG-- extra : convert_revision : e8395e0cc6ae1f180f9cd6f100795a1ac44aeed5
