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. --HG-- extra : convert_revision : b40ccfc42482d5a115e111dd897fa378d23c6c7d
