4d19bbeeeb MIPS is back to compiling and building now!
arch/alpha/isa_traits.hh:
    used for SimpleCPU instead of explicitly calling the namespace we declare in isa_traits.hhs
    so other archs. can use SimpleCPU
arch/mips/SConscript:
    dont include common_syscall or tru64
arch/mips/faults.cc:
arch/mips/faults.hh:
arch/mips/isa/formats/unimp.isa:
arch/mips/isa/formats/unknown.isa:
    Change Faults to new format
arch/mips/isa/decoder.isa:
    Fix readMiscReg access
    Made change so that you cant explicitly tell if a instruction nop,ehb,or ssnop... These are all variants
    of the sll instruction so I may need to make a separte class of instructions to handle thse better
arch/mips/isa/includes.isa:
    add isa_traits.hh and MipsISA included into every auto-gen file
arch/mips/isa_traits.cc:
    create copyMiscRegs function...
    delete useless code
arch/mips/isa_traits.hh:
    clean up for build
arch/mips/linux_process.cc:
    mem is now getMemPort(), linux process objects now take in a system argument
arch/mips/linux_process.hh:
    new argument for linux process
arch/mips/process.cc:
    add system
arch/mips/process.hh:
    add system variable
cpu/cpu_exec_context.cc:
    Change AlphaISA to TheISA
cpu/exec_context.hh:
    add readNextNPC and setNextNPC functions
cpu/simple/cpu.cc:
    include isa_traits for namespace declariation
cpu/simple/cpu.hh:
    PC & NPC access/modify functions
arch/mips/utility.hh:
    file needed for compile

    Sorted the switch headers, and added registerfile.hh, constants.hh, types.hh, and utility.hh.
arch/alpha/isa_traits.hh:
    Moved the register file types to registerfile.hh, small functions to utility.hh, and cleaned out alot of stuff that isn't necessary anymore.

11aead894d Updates for the quiesceEvent that was added to the XC.
Also several files need to include system.hh or symtab.hh.  This is because exec_context.hh has less #includes than before, requiring some of the files that include it to include some other files as well.

cpu/cpu_exec_context.cc:

b5f65c36c7 Corrected a mispelling of "unimplemented".
arch/sparc/stacktrace.hh:
    - Change the StackTrace code so that the class can more easily be
    cleaned out and reused to avoid extra allocations.
    - Allow trace() to accept a static instruction pointer so it can
    determine if the instruction is worth tracing.  This is moved from
    the CPU.
    - provide constants for special meaning PCs (user, console, unknown),
    instead of magic numbers
arch/sparc/stacktrace.hh:
    Added some typedefs for Addr and MachInst, and untemplatized StaticInstPtr
arch/sparc/stacktrace.hh:
    Made Addr a global type

arch/alpha/isa_traits.hh:
    Added getInstAsid and getDataAsid functions. These should be removed when the SimpleScalar cpu model is removed.
arch/sparc/isa_traits.hh:
    Added getInstAsid and getDataAsid functions. These should be removed when the SimpleScalar cpu model is removed. Also made some small fixes.
cpu/o3/alpha_cpu.hh:
    Added typedefs which are required now that there isn't a using namespace EV5.
cpu/o3/alpha_cpu_impl.hh:
    Some small changes so that ev5.hh isn't needed directly.
cpu/o3/cpu.hh:
    Removed including ev5.hh, and pushed retrieving the Asid into the MiscRegFile.
cpu/o3/regfile.hh:
    Removed the include of ev5.hh, using namespace EV5, and the now redundant ipr array.

cd62fed1a7 The a.out and ecoff object file formats will only be supported on Alpha for now.
arch/SConscript:
    aout_machdep.h and ecoff_machdep.h are no longer bridging headers, since support of these formats is limitted to alpha.
base/loader/exec_aout.h:
    Include the alpha specific version of aout_machdep.h, since only the alpha version of aout will be supported for now.
base/loader/exec_ecoff.h:
    Include the alpha specific version of ecoff_machdep.h, since only the alpha version of ecoff will be supported for now.

f15e492375 Steps towards setting up the infrastructure to allow the new CPU model to work in full system mode.
The major change is renaming the old ExecContext to CPUExecContext, and creating two new classes, ExecContext (an abstract class), and ProxyExecContext (a templated class that derives from ExecContext).

Code outside of the CPU continues to use ExecContext as normal (other than not being able to access variables within the XC).  The CPU uses the CPUExecContext, or however else it stores its own state.  It then creates a ProxyExecContext, templated on the class used to hold its state.  This proxy is passed to any code outside of the CPU that needs to access the XC.  This allows code outside of the CPU to use the ExecContext interface to access any state needed, without knowledge of how that state is laid out.

Note that these changes will not compile without the accompanying revision to automatically rename the shadow registers.

    Include new file, cpu_exec_context.cc.

e7825aab59 Changes to support automatic renaming of the shadow registers at decode time. This requires using an ExtMachInst (uint64_t) instead of the normal MachInst; the ExtMachInst is packed with extra decode context information. In the case of Alpha, the PAL mode is included.
The shadow registers are folded into the normal integer registers to ease renaming indexing.

Include the removed Opcdec class of instructions for faulting when a pal mode only instruction is decoded in non-pal mode.

arch/alpha/isa/main.isa:
    Changes for automatically using the shadow registers.  Now instructions must decode based on an ExtMachInst, which is a MachInst with any decode context information concatenated onto the higher order bits.

    The decoder (for Alpha) uses the 32nd bit in order to determine if the machine is in PAL mode.  If it is, then it refers to the reg_redir table to determine the true index of the register it is using.

    Also include the opcdec instruction definition.
arch/alpha/isa_traits.hh:
    Define ExtMachInst type that is used by the static inst in order to decode the instruction, given the context of being in pal mode or not.

    Redefine the number of Int registers, splitting it into NumIntArchRegs (32) and NumIntRegs (32 + 8 shadow registers).

    Change the dependence tags to reflect the integer registers include the 8 shadow registers.

    Define function to make an ExtMachInst.  Currently it is somewhat specific to Alpha; in the future it must be decided to make this more generic and possibly slower, or leave it specific to each architecture and ifdef it within the CPU.
arch/isa_parser.py:
    Have static insts decode on the ExtMachInst.
base/remote_gdb.cc:
    Support the automatic remapping of shadow registers.  Remote GDB must now look at the PC being read in order to tell if it should use the normal register indices or the shadow register indices.
cpu/o3/regfile.hh:
    Comment out the pal registers; they are now a part of the integer registers.
cpu/simple/cpu.cc:

26d7b5a4d1 Add quiesceNs, quiesceTime, quiesceCycles, and m5panic pseudo ops.

70b35bab57 Changes to put all the misc regs within the misc reg file. This includes the FPCR, Uniq, lock flag, lock addr, and IPRs.
They are now accessed by calling readMiscReg()/setMiscReg() on the XC.  Old IPR accesses are supported by using readMiscRegWithEffect() and setMiscRegWithEffect() (names may change in the future).

arch/alpha/alpha_memory.cc:
    Change accesses to IPR to go through the XC.
arch/alpha/ev5.cc:
    Change accesses for IPRs to go through the misc regs.
arch/alpha/isa/decoder.isa:
    Change accesses to IPRs to go through the misc regs.  readIpr() and setIpr() are now changed to calls to readMiscRegWithEffect() and setMiscRegWithEffect().
arch/alpha/isa/fp.isa:
    Change accesses to IPRs and Fpcr to go through the misc regs.
arch/alpha/isa/main.isa:
    Add support for all misc regs being accessed through readMiscReg() and setMiscReg().  Instead of readUniq and readFpcr, they are replaced by calls with Uniq_DepTag and Fpcr_DepTag passed in as the register index.
arch/alpha/isa_traits.hh:
    Change the MiscRegFile to a class that handles all accesses to MiscRegs, which in Alpha include the FPCR, Uniq, Lock Addr, Lock Flag, and IPRs.
    Two flavors of accesses are supported: normal register reads/writes, and reads/writes with effect.  The latter are basically the original read/write IPR functions, while the former are normal reads/writes.

    The lock flag and lock addr registers are added to the dependence tags in order to support being accessed through the misc regs.
arch/alpha/stacktrace.cc:
cpu/simple/cpu.cc:
dev/sinic.cc:
    Change accesses to the IPRs to go through the XC.
arch/alpha/vtophys.cc:

    For now comment out some of the accesses to the misc regs until the proxy exec context is completed.

    Have accesses to the IPRs go through the XC.
kern/tru64/tru64.hh:

51647e7bec Enable building only selected CPU models via new scons
CPU_MODELS parameter.  For example:
scons CPU_MODELS="SimpleCPU,FullCPU" ALPHA_SE/m5.debug
Unfortunately the option is not sticky due to a scons
bug with saving & restoring ListOption parameters.

SConscript:
    Separate out cpu-model-specific files so they can be conditionally
    included based on value of new CPU_MODELS parameter.
    Most of these are now handled in cpu/SConscript, except for FullCPU
    which is still in this file.
arch/SConscript:
    The set of CPU-model-specific execute files must now be
    determined from the CPU_MODELS parameter, via the new
    cpu_models.py file.
    Also pass the list of configured CPU models to isa_parser.py.
arch/isa_parser.py:
    Move CpuModel definition and objects out to a
    separate file so they can be shared with scons.
    Global list of CPU models to generate code for is now
    controlled by command-line parameters (so we can do
    only a subset of the available ones).
build/SConstruct:
    Define new CPU_MODELS ListOption.
cpu/static_inst.hh:
    Rename static_inst_impl.hh to static_inst_exec_sigs.hh.
