a4b31e8f6b Enable register windows.
arch/alpha/isa_traits.hh:
arch/mips/isa_traits.cc:
    Turned the integer register file into a class instead of a typedef to an array.
arch/alpha/regfile.hh:
    Changed the integer register file into a class instead of a typedef to an array. Also put the parts of the register file, ie the int, float, and misc register files, pc, npc, and nnpc, behind accessor functions. Added a changeContext function, and ContextParam and ContextVal types, so that things like the register window can be changed through call backs.
arch/mips/isa_traits.hh:
    Turned the integer register file into a class instead of a typedef to an array. Also moved a "using namespace" into the namespace definition.
arch/sparc/isa_traits.hh:
    Turned the integer register file into a class instead of a typedef to an array. Also "fixed" the max number of src and dest regs. They may need to be even larger.
arch/sparc/regfile.hh:
    Changed the integer register file into a class instead of a typedef to an array. Also put the parts of the register file, ie the int, float, and misc register files, pc, npc, and nnpc, behind accessor functions. Added a changeContext function, and ContextParam and ContextVal types, so that things like the register window can be changed through call backs. Created setCWP and setAltGlobals functions for the IntRegFile.
cpu/cpu_exec_context.hh:
    Used the accessor functions for the register file, and added a changeRegFileContext function to call back into the RegFile. Used the RegFile clear function rather than memsetting it to 0.
cpu/exec_context.hh:
    Added the changeRegFileContext function.
cpu/exetrace.cc:
    Use the TheISA::NumIntRegs constant, and use readReg now that the integer register file is a class instead of an array.
cpu/exetrace.hh:
    Get the address of the regs object, now that it isn't an array.

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.

    Changes to automatically map the shadow registers if the instruction is in PAL mode.

arch/alpha/isa/unimp.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.
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:
    Create an ExtMachInst to decode on, based on the normal MachInst and the PC of the instructoin.
cpu/static_inst.hh:
    Change from MachInst to ExtMachInst to support shadow register renaming.

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.

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.

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

cpu/o3/commit_impl.hh:
cpu/o3/fetch_impl.hh:
dev/baddev.cc:

cpu/o3/regfile.hh:

cpu/simple/cpu.hh:

dev/ns_gige.cc:
    Changed Fault to Fault *, and removdd underscores from fault names.
dev/sinic.cc:
    Changed Fault to Fault *, and removed the underscores from fault names.
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.

82f2ae56ed Alot of changes to push towards ISA independence. Highlights are renaming of the isa_desc files, movement of byte_swap.hh into sim, and the creation of arch/isa_traits.hh
SConscript:
    Moved some files out of targetarch. The either no longer need to be there, never needed to be there, or should be referred to directly in arch/alpha due to there strictly alpha content.

368882a847 Fix timing modeling of faults: functionally the very next instruction after
a faulting instruction is the fault handler, which appears as an independent
instruction to the timing model.  New code will stall fetch and not fetch the
fault handler as long as there's a faulting instruction in the pipeline (i.e.,
the faulting inst has to commit first).

Also fix Ali's bad-address assertion that doesn't apply to full system.

Added some more debugging support in the process.  Hopefully we'll move to the new
cpu model soon and we won't need it anymore.

arch/alpha/alpha_memory.cc:
    Reorganize lookup() so we can trace the result of the lookup as well.
arch/alpha/isa_traits.hh:
    Add NoopMachInst (so we can insert them in the pipeline on ifetch faults).
base/traceflags.py:
    Replace "Dispatch" flag with "Pipeline" (since I added similar
    DPRINTFs in other pipe stages).
cpu/exetrace.cc:
    Change default for printing mis-speculated instructions to true (since
    that's often what we want, and right now you can't change it from the
    command line...).

d53c6c168a Get software prefetching to work in full-system mode.
Mostly a matter of keeping prefetches to invalid addrs
from messing up VM IPRs.  Also discovered that wh64s were
not being treated as prefetches, when they really should be
(for the most part, anyway).

arch/alpha/alpha_memory.cc:
arch/alpha/alpha_memory.hh:
    - Get rid of intrlock flag for locking VM fault regs (a la EV5);
    instead, just don't update regs on VPTE loads (a la EV6).
    - Add NO_FAULT MemReq flag to indicate references that should not
    cause page faults (i.e., prefetches).
arch/alpha/ev5.cc:
    - Get rid of intrlock flag for locking VM fault regs (a la EV5);
    instead, just don't update regs on VPTE loads (a la EV6).
    - Add Fault trace flag.
arch/alpha/isa_desc:
    - Add NO_FAULT MemReq flag to indicate references that should not
    cause page faults (i.e., prefetches).
    - Mark wh64 as a "data prefetch" instruction so it gets controlled
    properly by the FullCPU data prefetch control switch.
    - Align wh64 EA in decoder so issue stage doesn't need to worry about it.
arch/alpha/isa_traits.hh:
    - Get rid of intrlock flag for locking VM fault regs (a la EV5);

a896960cbf FastCPU model added. It's very similar to the SimpleCPU, just without a lot of the stats tracking.
Also various changes to make the CPU model less ISA dependent, which includes moving the code that checks for interrupts up to the ISA level, moving code that zeroes the zero registers up to the ISA level, and removing opcode and ra from the regfile.

arch/alpha/alpha_memory.cc:
    The regfile has been changed so it no longer has the opcode and ra.  Instead the xc holds the actual instruction, and from there the opcode and ra can be obtained with OPCODE() and RA().
arch/alpha/ev5.cc:
    Moved code that once existed within simpleCPU to ev5, and templatized it.
    This way the CPU models can call processInterrupts and the ISA specific interrupt handling is left to the ISA's code.
    Also moved ISA specific zero registers from simpleCPU to here.
arch/alpha/ev5.hh:
    Added macros for obtaining the opcode and ra from the instruction itself, as there is no longer opcode or ra in the regfile.
arch/alpha/isa_desc:
    Added in declarations for the FastCPU model.
arch/alpha/isa_traits.hh:
    Removed opcode and ra from the regfile.  The xc now holds the actual instruction, and the opcode and ra can be obtained through it.
    Also added the declaration for the templated zeroRegisters() function, which will set the zero registers to 0.
arch/isa_parser.py:
    Added in FastCPUExecContext so it will generate code for the FastCPU model as well.
cpu/exec_context.cc:
    Added in a more generic trap function so "ev5_trap" doesn't need to be called.  It currently still calls the old method, with plans for making this ISA dependent in the future.
cpu/exec_context.hh:
    Exec context now has the instruction within it.  Also added methods for exec context to read an instruction from memory, return the current instruction, and set the instruction if needed.
    Also has declaration for more generic trap() function.
cpu/simple_cpu/simple_cpu.cc:
    Removed references to opcode and ra, and instead sets the xc's instruction with the fetched instruction.
cpu/static_inst.hh:
    Added declaration for execute() using FastCPUExecContext.
