3d99b4a544 Fixes to SPARC syscall emulation mode.
arch/sparc/isa/base.isa:
    Added a set of abbreviations for the different condition tests.
arch/sparc/isa/decoder.isa:
    Fixes and additions to get syscall emulation closer to working.
arch/sparc/isa/formats/branch.isa:
    Fixed branches so that the immediate version actually uses the immediate value
arch/sparc/isa/formats/integerop.isa:
    Compute the condition codes -before- writing to the state of the machine.
arch/sparc/isa/formats/mem.isa:
    An attempt to fix up the output of the disassembly of loads and stores.
arch/sparc/isa/formats/trap.isa:
    Added code to disassemble a trap instruction. This probably needs to be fixed up so there are immediate and register versions.
arch/sparc/isa/operands.isa:
    Added an R1 operand, and fixed up the numbering
arch/sparc/isa_traits.hh:
    SyscallNumReg is no longer needed, the max number of sources and destinations are fixed up, and the syscall return uses xcc instead of icc.
arch/sparc/linux/process.cc:
arch/sparc/linux/process.hh:
    Added a getresuidFunc syscall implementation. This isn't actually used, but I thought it was and will leave it in.
arch/sparc/process.cc:
arch/sparc/process.hh:
    Fixed up how the initial stack frame is set up.
arch/sparc/regfile.hh:
    Changed the number of windows from 6 to 32 so we don't have to worry about spill and fill traps for now, and commented out the register file setting itself up.
cpu/cpu_exec_context.hh:
cpu/exec_context.hh:
cpu/simple/cpu.hh:
sim/process.cc:
sim/process.hh:
    Changed the syscall mechanism to pass down the syscall number directly.

9e3d79694c Move to a model with a unified request object.
Constructor takes a bool to signify that it is either a cpu_request or not a cpu_request.
When accedding variables of a cpu_request it asserts that it is a cpu_request.
It also asserts that a value being read has been written at some point in time prior (not gaurnteeing it is up to date, but it was at least written before read).

There is also a isCpuReq() function to determine if this is a cpu_request.  It should be called before accesing a cpu_request only variable.

SConscript:
    Add compilation support for request.cc

mem/request.hh:
    Remove CpuRequest, make it a unified object.  Make variables private with accessor functions.

    May want to move things from .cc file into header (usually a assert() and either returning a value, or writting two).

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.

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.

0b2deb2a88 Fixes for full system compiling.
arch/alpha/arguments.cc:
    There will not be a phys mem ptr in the XC in the newmem.  This read will have to go through something else.
arch/alpha/ev5.cc:
    Remove instantiations of these functions for the FastCPU, as the FastCPU is not really used.  Also this messed up the ability to specify which CPU models are being built.

    Include sim/system.hh, and sort the includes.
cpu/simple/cpu.cc:

8e4ec55703 Changed the floating point register file into a class with appropriate accessor functions. The width of the floating point register to access can be specified, and if not, it will be accessed at its "natural" width. That is, the width of each individual register. Also, the functions which access the bit representation of floating point registers can use the blahblahBits functions now instead of blahblahInt.
arch/alpha/arguments.cc:
    Renamed readFloatRegInt to readFloatRegBits
arch/alpha/ev5.cc:
    Removed the Double from setFloatRegDouble
arch/alpha/registerfile.hh:
    Changed the floating point register file from a union of arrays to a class with appropriate accessor functions. The interface is necessary for SPARC.
arch/alpha/types.hh:
    Changed the FloatReg type from a union of uint64_t and double to a double, and defined a new type FloatRegBits which is a uint64_t and is used to return the bits which compose a floating point register rather than the value of the register.
arch/isa_parser.py:

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.

SConscript:
    Include new file, cpu_exec_context.cc.

    Avoid directly accessing objects within the XC.
arch/alpha/ev5.cc:
    Avoid directly accessing objects within the XC.

    KernelStats have been moved to the BaseCPU instead of the XC.
arch/alpha/isa_traits.hh:
    Remove clearIprs().  It wasn't used very often and it did not work well with the proxy ExecContext.
cpu/base.cc:
    Place kernel stats within the BaseCPU instead of the ExecContext.

    For now comment out the profiling code sampling until its exact location is decided upon.
cpu/base.hh:
    Kernel stats are now in the BaseCPU instead of the ExecContext.
cpu/base_dyn_inst.cc:
cpu/base_dyn_inst.hh:
cpu/memtest/memtest.cc:
cpu/memtest/memtest.hh:
    Changes to support rename of old ExecContext to CPUExecContext.  See changeset for more details.
cpu/exetrace.cc:
    Remove unneeded include of exec_context.hh.
cpu/intr_control.hh:

kern/system_events.cc:
    Avoid accessing objects directly within the XC.  Also kernel stats are now in the BaseCPU.
sim/process.cc:
sim/process.hh:
    Avoid accessing regs directly within an ExecContext.  Instead use a CPUExecContext to initialize the registers and copy them over.
cpu/cpu_exec_context.cc:
    Rename old ExecContext to CPUExecContext.  This is used by the old CPU models to store any necessary architectural state.  Also include the ProxyExecContext, which is used to access the CPUExecContext's state in code outside of the CPU.
cpu/cpu_exec_context.hh:
    Rename old ExecContext to CPUExecContext.  This is used by the old CPU models to store any necessary architectural state.  Also include the ProxyExecContext, which is used to access the CPUExecContext's state in code outside of the CPU.

    Remove kernel stats from the ExecContext.
