48f2626eac These fixes now allow all of the 20 mips tests to work properly!
Floating Point Mips Tests still need to be added, tested, and debugged.

arch/mips/isa/decoder.isa:
    Fix mult and multu instructions. This semantic error causes the problem: <int64> = <int32> * <int32>. Although I was placing
    the output into a 64-bit integer the multiply was just doing a 32-bit multiply so the solution is to just use
    the 'sd' & 'ud' operands so that the ISA parser will use the int64_t and uint64_t types in calculation.
arch/mips/isa/formats/int.isa:
    Trace output fix. Don't print first comma unless there is a destination register for sure!

5afed24e1c Changes that get rid of the OSFlags and derive a new class of this format <architecture>-<OS>.
This class is derived from the original <OS> class and is used to define information that
is both architecure and OS specific (for example, the AlphaLinux class is derived from the
Linux class and defined in arch/alpha/linux/linux.hh).

SConscript:
    no need to compile linux.cc and tru64.cc now, since openFlagsTable has been moved
arch/alpha/SConscript:
    compile linux.cc and tru64.cc within alpha arch.
arch/alpha/linux/process.cc:
    template syscall functions on AlphaLinux instead of Linux ... AlphaLinux is derived off of Linux
arch/alpha/tru64/process.cc:
    template syscall functions on AlphaTru64 instead of Linux ... AlphaTru64 is derived off of Linux
    moved tableFunc syscall function into this file
arch/mips/SConscript:
    compile mips_linux.cc for openFlags table
arch/mips/isa_traits.hh:
    remove constants from here
arch/mips/linux_process.cc:
    template syscall functions on MipsLinux instead of Linux ... MipsLinux is derived off of Linux
kern/linux/linux.hh:

kern/tru64/tru64.hh:
    remove OSFlags def., openFlagTable, and tableFunc ...

arch/alpha/linux/linux.cc:
    defines openFlagTable
arch/alpha/linux/linux.hh:
arch/alpha/tru64/tru64.hh:
    Alpha Linux constants placed here in class derived from Linux class
arch/alpha/tru64/tru64.cc:

arch/mips/mips_linux.cc:

    binary is loaded

    Add a constructor to packet to set the result to unknown and a reset
    method in the case it's being reused
mem/vport.hh:
    don't need are own read/write methods since the base functional port
    ones call writeBlob readBlob which do the translation for us

cab1af2ee8 Clean up mmapFunc.
sim/syscall_emul.hh:
    Clean up mmapFunc: args should be aligned and PageTable::allocate
    already handles multi-page allocations, so most of thw work done here
    was unnecessary (as far as I can tell).  I didn't test this beyond
    compiling though...

arch/mips/isa/decoder.isa:
    Make unimplemented instructions Fail instead of just Warn

arch/mips/isa/formats/branch.isa:
    Fix disassembly

    Add sign extend Immediate and zero extend Immediate to Int class.

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

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.

    Fixed the assert and comment to check that the Num_Syscall_Descs is less than or equal to 284. Why does this assert need to exist anyway?
base/loader/elf_object.cc:
    Cleared out comments about resolved issues.
cpu/simple/cpu.cc:
    Use NNPC for both SPARC and MIPS, instead of just MIPS

5936c79ba0 Add a functional port that is used to load the original binaries in FS
SE mode now has a port that goes to whatever toplevel mem object the
CPU sees that does the appropriate translation for syscall emulation

    translating port is a syscall emu only source
arch/alpha/system.cc:

cpu/cpu_exec_context.cc:

    support writing to a cache

mem/translating_port.hh:

e196d20d9d Make TranslatingPort be a type of Port rather than something special
arch/alpha/arguments.cc:
    rather than returning 0, put a panic in... it will actually make us fix
    this rather than scratching our respective heads
base/loader/object_file.cc:
base/loader/object_file.hh:
    Object loader now takes a port rather than a translating port
cpu/cpu_exec_context.cc:
cpu/cpu_exec_context.hh:
sim/process.cc:
    Make translating port a type of port rather than anything special
cpu/simple/cpu.cc:
    no need to grab a port from the cpu anymore
mem/physical.cc:
    add an additional type of port to physicalmemory called "functional"
    Only used for functional accesses (loading binaries/syscall emu)
mem/port.hh:
    make readBlok/writeBlob virtual so translating port can do the
    translation first
mem/translating_port.cc:
mem/translating_port.hh:
    Make TranslatingPort inherit from Port
sim/system.cc:
    header file that doesn't exit removed

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.
cpu/exec_context.hh:
    Remove getPhysMemPtr() function.
cpu/exetrace.cc:
    Include sim/system.hh, and sort the includes.
cpu/simple/cpu.cc:
    Fixes for full system compilation.
kern/system_events.cc:
    Remove include of encumbered FullCPU.  The branch prediction will need to be fixed up in a more generic way in the future.
