98cf57fb89 CheckerCPU: Add function stubs to non-ARM ISA source to compile with CheckerCPU 
Making the CheckerCPU a runtime time option requires the code to be compatible
with ISAs other than ARM.  This patch adds the appropriate function
stubs to allow compilation.

dc0e629ea1 Implement Ali's review feedback. 
Try to decrease indentation, and remove some redundant FullSystem checks.

48b6636d01 MIPS: Consolidate TLB related faults. 
Pass in a bool to indicate if the fault is from a store instead of having two
different classes. The classes were also misleadingly named since loads are
also processed by the DTB but should return ITB faults since they aren't
stores. The TLB may be returning the wrong fault in this case, but I haven't
looked at it closely.

110c59b414 MIPS: Get rid of cruft in the fault classes. 
Get rid of Fault classes left over from when this file was copied from Alpha,
and rename ArithmeticOverflowFault to be IntegerOverflowFault and get rid of
the old IntegerOverflowFault stub. The Integer version is what's actually in
the manual, but the Arithmetic version had the implementation.

eddac53ff6 trace: reimplement the DTRACE function so it doesn't use a vector 
At the same time, rename the trace flags to debug flags since they
have broader usage than simply tracing.  This means that
--trace-flags is now --debug-flags and --trace-help is now --debug-help

b289966a78 Mem: Reclaim some request flags used by MIPS for alignment checking. 
These flags were being used to identify what alignment a request needed, but
the same information is available using the request size. This change also
eliminates the isMisaligned function. If more complicated alignment checks are
needed, they can be signaled using the ASI_BITS space in the flags vector like
is currently done with ARM.

d8a34a9745 mips-tlb-fix: check for alignment faults.\nMIPS was never updated to use TLBS correcty in SE mode. The error was forwarding translations directly to pageTable. The TLB should check for alignment faults at bare minimum here but in the long run we should be using TLBs in SE mode for MIPS. 2009-04-18 10:42:29 -04:00

54cc0053f0 params: Deprecate old-style constructors; update most SimObject constructors. 
SimObjects not yet updated:
- Process and subclasses
- BaseCPU and subclasses

The SimObject(const std::string &name) constructor was removed.  Subclasses
that still rely on that behavior must call the parent initializer as
  : SimObject(makeParams(name))
