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:
    Change access to the IPR to go through the XC.
arch/isa_parser.py:
    Change generation of code for control registers to use the readMiscReg and setMiscReg functions.
base/remote_gdb.cc:
    Change accesses to the IPR to go through the XC.
cpu/exec_context.hh:
    Use the miscRegs to access the lock addr, lock flag, and other misc registers.
cpu/o3/alpha_cpu.hh:
cpu/simple/cpu.hh:
    Support interface for reading and writing misc registers, which replaces readUniq, readFpcr, readIpr, and their set functions.
cpu/o3/alpha_cpu_impl.hh:
    Change accesses to the IPRs to go through the miscRegs.
    For now comment out some of the accesses to the misc regs until the proxy exec context is completed.
cpu/o3/alpha_dyn_inst.hh:
    Change accesses to misc regs to use readMiscReg and setMiscReg.
cpu/o3/alpha_dyn_inst_impl.hh:
    Remove old misc reg accessors.
cpu/o3/cpu.cc:
    Comment out old misc reg accesses until the proxy exec context is completed.
cpu/o3/cpu.hh:
    Change accesses to the misc regs.
cpu/o3/regfile.hh:
    Remove old access methods for the misc regs, replace them with readMiscReg and setMiscReg.  They are dummy functions for now until the proxy exec context is completed.
kern/kernel_stats.cc:
kern/system_events.cc:
    Have accesses to the IPRs go through the XC.
kern/tru64/tru64.hh:
    Have accesses to the misc regs use the new access methods.

63db9860cf Make sure cpu/static_inst_exec_sigs.hh get rebuilt when
CPU_MODELS parameter changes.

arch/SConscript:
    Fix typo in comment.
cpu/SConscript:
    Convert exec signature generator to Action so we can add dependency
    on CPU_MODELS environment var.
    Print nicer string while we're at it.
    Also add some comments.

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.

1166d4f0bf Get rid of the xc from the alphaAccess/alphaConsole backdoor device.
Now allocate an array of stacks indexed by cpu number which specify
cpu stacks and are initialized by cpu 0. Othe cpus spin waiting for
their stacks before continuing. This change *REQUIRES* a the new
console code to operate correctly.

cpu/o3/cpu.cc:
cpu/simple/cpu.cc:
cpu/simple/cpu.hh:

    instead of the bootstrap variables, add space for 64 cpu stacks in the

99484cfae8 Create a Builder object for .isa files in arch/SConscript.
Start using SCons File objects to avoid fixed paths in
subordinate SConscripts.

SConscript:
    Push isa_parser stuff (including .isa scanner) down into
    arch/SConscript.
arch/SConscript:
    Create a Builder object for .isa files, including existing scanner.
    Return file objects generated by isa-specific SConscript
    back up to parent.
arch/alpha/SConscript:
arch/mips/SConscript:
arch/sparc/SConscript:
    Convert sources to scons File objects, so file names can be specified
    relative to the current directory.
    Invoke new builder for isa description, and get generated sources from
    there (instead of listing them explicitly).
arch/isa_parser.py:
    Get rid of third argument ("include_path").
    It was a pain to generate this from scons, and it turned out
    it's not needed anyway, since the only included file
    (decoder.hh) will be in the same directory as the sources.

485568efa9 Fixes to handle generating the initiateAcc and completeAcc functions a little more cleanly.
arch/alpha/isa/mem.isa:
    Avoid explicitly declaring the Mem variable.  Instead break up the code blocks used to generate the initiate and complete functions.  The templates reflect which operands need to be declared for each function (src, dest, or both).

    Loads use both the EA code and mem acc code for the initiate, and memacc code and postacc code for the complete.
    Stores use both the EA code and mem acc code for the initiate, and only post acc code for the complete.
arch/isa_parser.py:
    Remove hack for mem ops.

10c79efe55 Changed the fault enum into a class, and fixed everything up to work with it. Next, the faults need to be pulled out of all the other code so that they are only used to communicate between the CPU and the ISA.
SConscript:
    The new faults.cc file in sim allocates the system wide faults. When these faults are generated through a function interface in the ISA, this file may go away.
arch/alpha/alpha_memory.cc:
    Changed Fault to Fault * and took the underscores out of fault names.
arch/alpha/alpha_memory.hh:
    Changed Fault to Fault *. Also, added an include for the alpha faults.
arch/alpha/ev5.cc:
    Changed the fault_addr array into a fault_addr function. Once all of the faults can be expected to have the same type, fault_addr can go away completely and the info it provided will come from the fault itself. Also, Fault was changed to Fault *, and underscores were taken out of fault names.
arch/alpha/isa/decoder.isa:
    Changed Fault to Fault * and took the underscores out fault names.
arch/alpha/isa/fp.isa:
    Changed Fault to Fault *, and took the underscores out of fault names.
arch/alpha/isa/main.isa:
    Changed Fault to Fault *, removed underscores from fault names, and made an include of the alpha faults show up in all the generated files.
arch/alpha/isa/mem.isa:
    Changed Fault to Fault * and removed underscores from fault names.

    Changed Fault to Fault *, and removed underscores from fault names. This file probably shouldn't use the Unimplemented Opcode fault.

cpu/o3/fetch_impl.hh:
dev/baddev.cc:
    Changed Fault to Fault *, and removed underscores from the fault names.
cpu/o3/regfile.hh:

dev/ns_gige.cc:

dev/sinic.cc:

dev/uart8250.cc:
    Chanted Fault to Fault *, and removed underscores from fault names.
kern/kernel_stats.cc:
    Removed underscores from fault names, and from NumFaults.
kern/kernel_stats.hh:
    Changed the predeclaration of Fault from an enum to a class, and changd the "fault" function to work with the classes instead of the enum. Once there are no system wide faults anymore, this code will simplify back to something like it was originally.
sim/faults.cc:
    This allocates the system wide faults.
sim/faults.hh:
    This declares the system wide faults.
sim/syscall_emul.cc:
sim/syscall_emul.hh:
    Removed the underscores from fault names.

2d04f18674 Gives separate methods for initiating and completing a memory access, which will be helpful for the merged memory model.
arch/alpha/isa/mem.isa:
    Include methods that allow a memory operation to be split between the part that initiates the access, and the part that completes the access.  In these functions the Mem variable is explicitly declared; in the default execute functions, the Mem variable is still handled through %(op_decl)s.
arch/isa_parser.py:
    Include recording the type of the memory access variable so that it can be used if it needs to be explicitly declared in a template.

    Have memory operands consider themselves neither a source nor a destination to avoid including themselves on the op_src_decl list or the op_dest_decl list.

    Record op_src_decl and op_dest_decl lists to allow for declaring only source or destination operands.  This is needed for the split memory access methods.
