97429d8eee Redo the FloatRegFile using unsigned integers
Edit the convert_and_round function which access FloatRegFile

arch/isa_parser.py:
    recognize when we are writing a 'uint64_t' FloatReg and set the width appropriately
arch/mips/isa/decoder.isa:
    Send a 'float' to the convert function instead of a unsigned word. Do this so we dont have to worry about the
    bit manipulation ourselves. We can just concern ourselves with values.

8a9d270f6c move code from packet.hh to packet.cc and packet_impl.hh
fix very annoying not-compiler bug

arch/sparc/regfile.hh:
    You have not included an out-of-class definition of your static members. See [9.4.2]/4 and about a billion gcc bug reports.
    If statements get around the problem through some magic, and than seems nicer that putting a definition of them in a c file
    somewhere.
cpu/simple/cpu.cc:
    get() and set() do the conversion now
dev/io_device.hh:
    need get() and set() defentions in all the devices
mem/packet.cc:
mem/packet.hh:

a8fbc4ec76 Got hello world to work!
arch/sparc/isa/decoder.isa:
    Made sure if a register was assigned to along some control path, then all paths on which no exception would block commit set a value as well. Also, Rs1 is treated as signed for bpr instructions.
arch/sparc/isa/formats/integerop.isa:
    Added an IntOpImm11 class which sign extends the SIMM11 immediate field.
arch/sparc/isa/formats/mem.isa:
    Fixed how offsets are used, and how disassembly is generated.
arch/sparc/linux/process.cc:
    Added fstat and exit_group syscalls.

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

81a735a716 fs now gets to the point where it would really like a filesystem.
Time to make the ide device work

arch/alpha/system.cc:
    write the machine type and rev in the correct place
cpu/simple/cpu.cc:
    reset the packet structure every time it's reused... wow the
    simple cpu code  for talking to memory is getting horrible.
dev/alpha_console.cc:
    move the setAlphaAccess to startup() to make sure that the console
    binary is loaded
dev/tsunami_cchip.cc:
dev/tsunami_pchip.cc:
dev/uart8250.cc:
    fix a couple of bugs injected in the newmem fixes
mem/bus.cc:
    More verbose bus tracing
mem/packet.hh:
    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

4fe89f7232 add OSFlags struct to AlphaISA/MipsISA namespace. The OS classes then use these OSFlags to access architecture-specific AND OS-specific
flags for their functions (e.g. OS::OSFlags::TG_MAP_ANONYMOUS)...

arch/alpha/tru64/process.cc:
sim/syscall_emul.hh:
    Add OSFlags to code
arch/mips/isa/decoder.isa:
    slight decoder changes (more stylistic then anything)
arch/mips/isa/formats/util.isa:
    spacing
arch/mips/isa_traits.hh:
    add OSFlags struct to MipsISA namespace. The OS classes then use these OSFlags to access architecture-specific and OS-specific
    flags for their functions
kern/linux/linux.hh:
    remove constant placement ... define OSFlags in linux.hh
kern/tru64/tru64.hh:
    define OSFlags in tru64

08d9e0ea7a change how much of the param string is copied into the kenel
Set locked flag if required
make SC always return success -- this needs to be fixed at some point
fix a couple of things

FS executes a bit of console code before dying a horrible death

arch/alpha/linux/system.cc:
    only need to copy the length of the os flags param, not 256  bytes
cpu/simple/cpu.cc:
    Set the physical flag if required
    Make LL/SC always return success
mem/bus.cc:
    add some dprintfs and change a assert to a panic
mem/port.cc:
    delete the buffer with the [] operator
mem/request.hh:
    add a function to reset a request

82815e9170 Lots of MIPS test files :
Will remove these in future merge but it is just way easier to keep all these tests in
their own repo folder so I wont have to reset these up every time I pull from bitkeeper
