arch/alpha/alpha_memory.cc:
arch/alpha/isa/decoder.isa:
Added news where faults are created.
arch/alpha/ev5.cc:
Changed places where a fault was compared to a fault type to use isA rather than ==
arch/alpha/faults.cc:
arch/alpha/faults.hh:
Changed Fault to be a RefCountingPtr
arch/alpha/isa/fp.isa:
Added a new where a FloatEnableFault was created.
arch/alpha/isa/unimp.isa:
arch/alpha/isa/unknown.isa:
Added a new where an UnimplementedFault is created.
base/refcnt.hh:
Added include of stddef.h for the NULL macro
cpu/base_dyn_inst.cc:
Added a new where an UnimplementedOpcodeFault is created.
cpu/o3/alpha_cpu_impl.hh:
Changed places where a fault was compared to a fault type to use isA rather than ==. Also changed fault->name to fault->name()
cpu/o3/regfile.hh:
Added new where UnimplementedOpcodeFaults are created.
cpu/simple/cpu.cc:
Changed places where a fault was compared to a fault type to use isA rather than ==. Also added a new where an Interrupt fault is created.
dev/alpha_console.cc:
Added news where MachineCheckFaults are created.
dev/pcidev.hh:
Added news where MachineCheckFaults are generated.
dev/sinic.cc:
Changed places where a fault was compared to a fault type to use isA rather than ==. Added news where MachineCheckFaults are created. Fixed a problem where m5.fast had unused variables.
kern/kernel_stats.cc:
Commented out where _faults is initialized. This statistic will probably be moved elsewhere in the future.
kern/kernel_stats.hh:
Commented out the declaration of _fault. when fault() is called, the fault increments its own stat.
sim/faults.cc:
sim/faults.hh:
Changed Fault from a FaultBase * to a RefCountingPtr.
