805b9cf1d5 Found and fixed 3 decoder.isa bugs!!! Now the hello_world program runs for a while
before getting in a infinite loop. It actually "tries" to syscall too, but syscalls
aren't implemented just yet

arch/mips/faults.cc:
    more descriptive names for faults (will help future users as well as me!)
arch/mips/isa/base.isa:
    make sure we are printing out "BasicOp" format disassembly instructions as dest,src,src instead of src,src,dest
arch/mips/isa/decoder.isa:
    FIX LW/SW Bug!!!! I was actually loading a byte instead of a word
    FIX JALR Bug!!!! I was not saving the link address in R31 for this instruction
    FIX SLL/NOP Bug!!! We now recognize the varying flavors of sll,nop,ehb,& ssnop correctly
base/loader/elf_object.cc:
    change back to original way
base/loader/elf_object.hh:
    change back to original!

31a20c88c5 Add warning for ignored loadable ELF segments.
base/loader/elf_object.cc:
    Print warning if there are more than two loadable segments.
    We currently assume there are at most two (text & data), and that's
    held so far, but it would be nice not to silently ignore others.

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:
    Adjusted the makeRead and makeWrite functions to generate the new versions of readFloatReg and setFloatReg.
base/remote_gdb.cc:
kern/tru64/tru64.hh:
    Replaced setFloatRegInt with setFloatRegBits

f045b110cf Have a copyRegs function defined in the ISA that copies registers from one ExecContext to another ExecContext. This makes it easier for anything that needs to copy architected registers to do so in an ISA independent fashion.

1141610a01 Bump up NFS wait time in qdo (since this has been causing
problems in pool regressions).

util/qdo:
    Bump up hardcoded NFS wait time from 45 sec to 90 sec (and
    print threshold from 10 sec to 30 sec).  Would be even
    nicer to make these cmd-line params, but nobody would use
    them anyway.

3ed62ad025 Work towards factoring isa_traits.hh into smaller, more specialized files.
arch/SConscript:
    Sorted the switch headers, and added registerfile.hh, constants.hh, types.hh, and utility.hh.
arch/alpha/isa_traits.hh:
    Moved the register file types to registerfile.hh, small functions to utility.hh, and cleaned out alot of stuff that isn't necessary anymore.
base/loader/ecoff_object.cc:
base/loader/elf_object.cc:
cpu/pc_event.hh:
cpu/static_inst.hh:
mem/port.hh:
sim/faults.cc:
sim/system.hh:
    base/misc.hh isn't included through isa_traits.hh anymore.
cpu/simple/cpu.cc:
    Added include for arch/utility.hh

e3651fde0b Moved MaxAddr.
sim/host.hh:
    Moved MaxAddr from arch to here, since it depends only on the Addr type.
