fixing things, partly by ignoring CPU models
that don't currently compile.
SConscript:
Split sources for fast, simple, and o3 CPU models into
separate source lists. For now none of these are included
in the base source list, so you won't get any CPU models
at all... but we still can't compile the other stuff so
it's not an issue.
Also get rid of obsolete encumbered/mem file.
base/loader/aout_object.cc:
base/loader/aout_object.hh:
base/loader/ecoff_object.cc:
base/loader/ecoff_object.hh:
base/loader/elf_object.cc:
base/loader/elf_object.hh:
base/loader/object_file.hh:
cpu/exec_context.cc:
sim/process.cc:
sim/system.cc:
sim/system.hh:
FunctionalMemory -> Memory
cpu/pc_event.hh:
Get rid of unused badpc.
cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
Move Port functions into .cc file.
mem/port.hh:
Make recvAddressRangesQuery panic by default instead
of being abstract... do CPUs need to implement this?
mem/request.hh:
Add prefetch flags.
sim/syscall_emul.hh:
Start to fix...
